EagleLight LED Candelabra Light for LED Chandelier Light Bulbs

EagleLight LED Candelabra Light Bulb

Eaglelight.com has released a new LED light bulb with ‘filament’ like shine from an energy-efficient LED source.  The bulb places the LEDs on a ribbon of circuit board that is twisted inside a glass enclosure to create an incandescent like lighting source.  These bulbs have a warm white look and have a far greater beam angle than traditional LED bulbs, as the LEDs are up off the base and shine in many directions.  Visit EagleLight.com to see the LED Candelabra bulb.

This bulb is available in both LED Candelabra bulb shape and in a traditional incandescent, house hold bulb shape, technically known as an A19.  The candelabra bulb shape has a E12 base type, typical of most US made chandeliers.  E12 is the smaller of the two typical candelabra bases, the bulb is also available in the larger E14 base on special order.  The A19, traditional house hold bulb shape comes with a medium screw base also know as a E26.

These bulbs are available in a warm white, like the one shown to the right as well as natural white that has a bit less yellow.

The U.S. Department of Energy (DOE) has released analysis findings for markets where light-emitting diodes (LEDs) compete with traditional lighting sources (e.g., incandescent and fluorescent). The January 2011 report provides estimates of current energy savings, plus potential savings if these markets switched to LEDs overnight.

DOE analyzed the following markets:

  1. Four general-illumination applications
    1. PAR, BR, and R replacement lamps;
    2. MR16 replacement lamps;
    3. 2-foot by 2-foot troffer fixtures; and
    4. general service A-type replacement lamps
    5. Four outdoor applications
      1. roadway,
      2. parking,
      3. area and flood, and
      4. residential
      5. Four applications for consumer electronic displays
        1. televisions,
        2. laptops,
        3. monitors, and
        4. mobile handsets.

LEDs in these markets saved approximately 3.9 terawatt-hours in 2010, equivalent to the electricity needed to power more than a quarter-million average U.S. households.

If these markets switched to LEDs overnight, the energy savings would be the equivalent of taking 21 million residential households off the grid based on 2010 performance level.

If LED replacements within each market improve according to DOE’s predictions for 2020, the energy savings would be equivalent to taking nearly 32 million households off the grid.

California passes a new law that takes effect January 1, 2011 requiring improved energy efficiency in all light bulbs in the State.

California consumers also will save money buying LED lighting.  Eaglelight.com has the best in energy efficient LED lights and now there is much more reason than ever before to change your lighting to LEDs.

A new federal law will start saving consumers money by improving the energy efficiency standard for incandescent light bulbs sold in California on or after January 1, 2011.

The standard – Energy Independence and Security Act of 2007 (EISA) – will save California consumers money with new bulbs that offer the same amount of light while using less power. Passed by Congress and signed by President George W. Bush, EISA created new energy efficiency standards for light bulbs. The law is designed to reduce energy use and associated pollution and make the United States less dependent on foreign sources of energy. While the country will adopt this standard on January 1, 2012, California was given authority to implement the national standards one year earlier to avoid the sale of 10.5 million inefficient 100-watt bulbs in 2011 which would cost consumers $35.6 million in higher electricity bills*.

Reducing energy use in California also results in improved environmental quality by avoiding the construction of new power plants and air pollution from burning fossil fuels.

The standard in California states that a 100-watt bulb manufactured on or after January 1, 2011 must use 28 percent less energy (i.e. a 100-watt bulb may not use more than 72 watts). The new 72-watt replacement bulb will provide the same amount of light (i.e. lumens), use less power, and cost less to operate.

New lighting technology has become more efficient than old-fashioned incandescent bulbs. Approximately 90% of the electricity used by traditional incandescent bulbs is wasted as heat instead of visible light. Replacing traditional incandescent light bulbs with more efficient halogen, compact fluorescent bulbs (CFL) or light-emitting diode (LED) bulbs will save consumers money while still offering same amount of light.

The new standard is technology neutral and allows consumers to choose among a variety of high-performance products for their replacement lighting. Additionally, it does not affect the existing supply of incandescent light bulbs stocked in retail stores or incandescent light bulbs already in use.

This standard builds on the California Energy Commission’s long and successful reputation of saving consumers money though energy efficiency standards. Since 1978, California’s appliance and building efficiency standards have saved more than $56 billion in electricity and natural gas costs.

“A straightforward guide to understanding, buying, installing and benefiting from energy saving LED home lighting. ht: kulekat

Domestic LED lighting is still seen as something of a novelty and many people don’t really understand what’s involved, where to use energy saving LED lighting, how to use domestic LED lights or what the issues are regarding installing low energy light bulbs.

For a start there is the cost, which puts many people off straight away because what they almost certainly don’t yet understand about low energy lighting is that when comparing an ultra low energy LED light bulb with a normal incandescent bulb or even an “energy saving” CFL light bulb they are not comparing like with like.

It’s hard to see how a domestic LED replacement light that costs many times more than the ordinary light bulbs you’ve always bought before could possibly save you money. But believe it – it will save a fortune and sooner than you might think.

Part of the reason is not only the energy saving that home LED lighting brings, but that word “replacement” – replacing conventional, halogen and so-called low-energy CFL bulbs with genuinely ultra low energy domestic LED lamps means quite simply you don’t have to replace light bulbs all the time because the lifespan of most LED lamps on sale today is a staggering 50,000 (or more) times that of a regular incandescent light bulb.

The fact is that even at today’s fuel prices you will save (yes, that is “will save” not “may save”) substantial sums of money by replacing existing domestic lighting systems with low energy LED home lighting alternatives. The following table gives a clue as to how much saving is possible from LED compared to CFL and incandescent lighting.

Type Wattage Total Lumens Lifespan Hours Annual Energy Cost Cost Over 5 Years
Incandescent 60W 840 1,000 8.00 1200.00
CFL 11W 770 8,000 1.45 217.50
LED 5W 625 50,000 0.40 60.00

Energy costs are based on the standard approximation of 10p per kWh, with average usage of 4 hours per day for a modest family home with 30 light bulbs.

Regardless of how closely the actual costs match your own circumstances, you can clearly see that LED light bulbs are nearly 4 times cheaper to run than CFLs and a massive 20 times cheaper than incandescent light bulbs.

That’s without factoring in the increased lifespan which means that even when comparing purchase prices, any LED that is less than 50 times more expensive than its incandescent counterpart actually works out cheaper in terms of purchase costs too.

As the future brings ever rising energy and thus electricity prices, due to the remorseless effects of supply and demand, the arguments for switching to energy saving domestic LED lighting become ever more compelling.

Not only are domestic LED lights becoming rapidly ever more powerful and versatile, they are also dropping massively in price. That’s for a simple reason, namely that domestic LED is the future of lighting. The major corporations in the lighting industry are all betting their businesses on LED home lighting and moving away from both regular incandescent and CFL “low energy” or “energy saving” light bulbs.

The reason is very simple: economics and survival in a new age of global warming and energy crises – the lighting industry is being forced to adopt effective energy saving lighting solutions, which means that you, me and everyone else is also about to be forced to adopt energy saving lighting – namely domestic LED lighting.

Not only that, but many governments are also actively engaged in phasing out conventional light bulbs, some as soon as only a couple of years hence. The energy (and hence real money) costs of both manufacturing and, quite literally, burning traditional light bulbs is becoming prohibitive to all concerned.

This is even before you factor in the environmental cost in terms of waste heat, CO2 output and disposal. The lifespan of incandescent bulbs is less than 2% that of LED lamps and in the case of CFLs (Compact Fluorescent Lamps), which still last only about 10% as long, there is the added problem that they contain highly toxic mercury vapour and must be disposed of in a controlled manner. Between legislative push and technological pull, the conclusion is inescapable: domestic LED lighting is coming to a home near you, real soon.

How And Where To Use Energy Saving Domestic LED Lighting

Then there is the question of where and how to use LED lighting in and around the home. Again, lack of familiarity with LED technology means that many people have only encountered domestic LED lighting in limited areas such as novelty lamps, high powered LED torches and solar powered LED garden lighting.

The availability of domestic LED lighting solutions is increasing at a phenomenal rate, but right now it is still fair to say that the best way to use LEDs in your own household is in the applications where LED lights excel.

Unlike a conventional incandescent lamp that scatters (mostly heat and some) light in all directions, an LED emits a very bright, pure light that is highly directional. This makes them absolutely ideal as replacement spot lights, particularly for replacing halogen lightswhich seem to be everywhere in the home these days, wasting heat and money in equal measure.

LED lamps also remain cool to the touch, since they convert nearly all their input electricity into light and don’t waste heat, and are therefore far safer than extremely hot halogen bulbs that can present a serious fire risk in some situations.

Although spot lights are commonly used as down lighters in a domestic setting, they are also perfect as display lighting, but can be difficult to install in some areas due to the very high temperatures associated with conventional incandescent spot lights.

Again, LED spot lights are ideal for illuminating display shelving, installing underneath shelves and kitchen units, and lighting the insides of cabinets and even wardrobes. They can be placed right next to delicate surfaces and other objects without the slightest risk of harm due to heat. This also open up new display lighting techniques since LED spot lights can be placed adjacent to even in among the feature on display.

Another area where you might consider using LED lights is mood lighting. This is an area that home LED lighting really opens up since many of the effects achievable with LED lighting are simply not possible using existing lighting technology. LED lights can emit and mix all manner of rich, vibrant colors and even change color dynamically. These can be directed against wall, floors and ceilings to alter the ambience of a room or can be concentrated as a focal point to draw attention.

In fact, some modern TV’s already incorporate LED mood lighting by back projecting colors according to the mood of the programme being shown, but you don’t need to spend out on an expensive new HDTV to get this effect. You can install LED mood lighting anywhere you like. Imagine being able to subtly alter the color scheme in your bedroom for example according to how you happen to be feeling at the time!

And of course, all these techniques can be readily exported to provide outdoor lighting where low-heat, low-energy LED lights make them safe and easy to install in the garden to provide courtesy lighting, illuminate particular features, or whatever takes your fancy really.

How To Begin Installing Low Energy LED Home Lighting

Installing LED replacement lamps throughout your home should be seen as an investment as well as an opportunity to introduce new, innovative and cost-efficient lighting ideas into your home. The upfront costs can be quite significant (even though the savings are equally as impressive and surprisingly quick to kick in) so it is sensible to tackle the conversion in several phases.

When you review which light bulbs to replace with low energy lighting, initially consider lights that you leave on a lot and/or don’t need to be very bright (night lights spring to mind). Old first generation LED lights are easily up to the job here, providing suitable light levels and able to be left running more or less permanently at almost no cost. They are also quite cheap since by modern domestic LED standards they are old technology.

Other obvious domestic applications to consider for initial replacement are those halogen spot lights, since most people have them installed in light clusters (say 10 or more down lighters in a kitchen or 4 or 5 spot lights on a rack in a bathroom). Kitchen lighting tends to be left on a lot and you will obviously get the best savings from those lights you normally use the most. The great thing about installing LED kitchen lighting using retrofit replacements for halogen lamps (MR16, GU10 and ES formats are all available) is that you get low power consumption and low heat output, so no more issues with being fire-rated. There are now hi power GU10 LED energy saving bulbs equal in power to GU10 50w halogen output but running at 9 watts that deliver the holy grail of full spectrum light, low power and long life.

If you already have display lighting, this again is a great area to tackle for all those reasons mentioned above. If you don’t as yet use display lighting then you should consider the opportunities that LED strip lights and spots provide. If you have any open or glazed display cabinets, shelves, recesses or features/ornaments then you can easily turn these effectively into light sources that add interest to a space by bouncing LED lights off reflective surfaces or using LED color wash effects.

Feature lighting – that is, a light source that is itself intended to be the focus of attention – can also be wonderfully enhanced with domestic LED lighting technology. Colored or color changing LEDs are an obvious example with the beautiful rich depth of colors available. But also, certain materials such as polished metal and cut glass are a match made in heaven for the bright, sparkling light that is unique to tiny, low heat, low energy domestic LED lighting clusters.

The next targets to pick on are any other areas around the house that use or would benefit from very bright directional light. Desk lamps and other reading lights are clear candidates since that is the whole point of a reading light – clean, bright light aimed where you actually want it.

Also worthy of consideration are any domestic light fittings that “throw” light – up lighters for example – where you could achieve a similar effect by bouncing light from an LED light source so that it is diffused over a wall or ceiling.

Last to consider are fittings that use the common or garden lampshade. These are actually designed to scatter light in all directions and although this effect can be achieved by replacement LED light bulbs, current technology does not yet provide as effective a substitute as for those applications that require bright directional light. This is set to change in the very near future though, so watch this space!

But in the mean time, you could consider halogen based replacements for ordinary light bulbs as an effective interim solution since these have very similar characteristics to GLS (General Lighting Service) light bulbs in terms of range of fittings and light quality and intensity, but bring the added benefits of lasting at least twice as long while using about one third less energy.

What To Look For When Buying Energy Saving LED Lights For The Home

So, which domestic low energy light bulbs should you buy? There are a number of points to review, the first being aesthetics. It’s all very well saving money with LED home lighting but the operative word here is “home”.

It’s your home and you have to live there, so make sure you like what you buy. Not least, because unlike an ordinary light bulb which is a) cheap and b) won’t last long, a domestic energy saving LED lamp is an investment that you will own for at least a decade or three.

Until you become more familiar with the bewildering variety of domestic LED lights available, the best way to find out what you like is to actually see some in action. Specialist lighting and home furnishings stores frequently have home LED lighting on display as do many larger DIY and department stores.

Don’t be confused either by the low wattage rating for energy saving domestic LED lamps. A 7w incandescent bulb would give scarcely any light at all, but a 7w LED bulb is extremely bright. You should become accustomed to these different rating values so you know what level brightness you want (but of course, if you actually visit a store you can see for yourself anyway). As a rough guide a ratio of 1:10 works well – in other words a 5w LED would be a good match for a 50w incandescent bulb.

The next thing you will be confronted by after power rating is “color”. This is a value such 4700K (where K indicates Kelvins – a temperature scale where 0 degrees is “absolute zero”).

All you need to know about color temperatures is that the lower the value, 2100K for example, the warmer and more yellow the light and conversely the higher the value, such as 5100K the colder and bluer the light will appear.

There is no hard and fast rule as to what color temperature is “best”. It depends on personal taste and what you require the light for – bright, closer to daylight color or a softer more gentle ambience. This color scale example gives an idea.

You get what you pay for. Be wary of buying energy saving LED lightbulbs direct from websites that are not clear about the origins of their products. There are many cheap and frankly nasty products out there (eBay sellers advertising stock shipped from China for example). The simple and safe advice when looking to buy LED lightbulbs direct is stick with top quality brands.

Unless you are simply purchasing more of a type of domestic LED light you have previously bought and were pleased with, always try to see an example of how it performs for your intended application. You don’t have to jump in with both feet – start by replacing just a few lights with LED substitutes and gradually learn how and where to use home LED lighting to best effect in a domestic setting. Very much the same techniques and guidelines apply as for designing regular home lighting, and as ever, the best way of understanding any new technology is by playing with it.

For a more in depth look at buying and installing energy saving LED home lighting check out this simple guide to buying LED home lighting and also this review of how to set about replacing halogen with LED.

An energy saving domestic LED lamp is not like an ordinary light bulb – you are not going to be replacing it after a year. LED Home Lighting – it really is the future, in more ways than you might have imagined.”

Did you know…

A 60 watt LED light-emitting diode light lasts over 30,000 hours and higher wattage LED lights often last over 100,000 hours.

LED lights burn a small fraction of the energy a regular or CFL light bulb uses to produce the same amount of light.

LED lights aren’t hot to the touch. Incandescent and CFL bulbs retain more heat due to the fact they aren’t transferring energy as efficiently and waste a lot of your electric bill making heat.

Old light bulbs pollute with dangerous mercury which can get into landfills and water supplies, and can harm you directly if the bulb breaks in front of you.

LED lights are a clean pure energy light source.

March 19, 2010… A visit to any stage production or concert makes it quickly apparent that computers have been involved in lighting for a long while, and in LED lighting since it first appeared in all its color-controlled glory. On-off-intensity-hue all get sent from the programmable controller to the individual receiver modules, that either contain or control the drivers that turn on and off the individual or banks of LEDs. For general purpose white lighting, we haven’t seen much of that yet. It makes sense, given that a) lighting already exists (I have some in both rooms!), b) doesn’t normally have much intelligence in most installations, and c) solid state lighting has pretty much been working to slot-in to ceilings or light poles where a light already was. You could make the LED luminaire smarter if you wanted, but then what? Nice to be able to talk, but only if you have someone to talk to.

Don’t get me wrong; I’m not implying that the current generation of LED lighting isn’t sophisticated, as many of them have microcontrollers built in. Basically, they are very dedicated little computers, like the ones that oversee a car’s convertible top operating in its proper sequence, and only when the driver door is closed and the speed is less then 5 MPH, or which differentiate between an underpass and a tunnel in figuring out to turn the headlights on or off. In some cases, especially for parking or street lights, manufacturers integrate-in the obvious daylight sensor, as well as motion sensors that may provide an off/dim/full capability. We saw an example of Beta LED’s motion-activated bi-level parking area versions in a tour at the last Raleigh DOE conference and it showed their clear-thinking design approach. See what you need to see, when you need to see it. You can see to the other end of the parking garage, and as you approach, up come the lights and you can see the details you need to miss the hubcaps while collecting the spare change in your direct path. If there was another car or pedestrian there, it would have already been on, so the safety “buffer zone” is pretty intuitive. Motion sensing makes sense in a lot of areas, from refrigerator cases to offices, and has been a challenge in the past as fluorescents really didn’t like the whole on and off thing, and required fairly long minimum cycle times to keep they, or their power sections, from burning out very prematurely. We’ve been told that a new generation of sensors and supplies, geared towards the capabilities of the LEDs, is a necessary answer.

In another intelligent approach, discussed at the November 2009 NY SSL Summit (visit www.SSLsummit.com for 2010/2011 plans), we heard from Elumen Lighting on the smarts built into their streetlights that provide for constant light output (lumen compensation), as well as timer- or sensor-based dimming. Since no one is really sure yet what precise behavior individual LED models will have over 50,000 to 100,000+ hours, they took the approach of whether they lose 5% or 10%, or later 20% or more of their output (or gain output for a period as has been observed for some types of LEDs), the intelligence in their units will dial the current up or down as needed to keep the light output in a target range. At the Summit, we also discussed the options that such an approach suggests for end of life issues. Turning up the juice leads to a predictable “shuts off when too much power is needed”, similar to what’s happening in current HID streetlights, but that’s 60,000 hours down the road, and without the annoying re-strike “feature” that keeps the cheaper ones running on a X minutes on, Y minutes off kind of cycle that drove us nutty in a previous house (had it not been quite as populated a street, or maybe if I just had a powerful enough pellet gun instead of just the 30-30, the nighttime torture may have ended more quickly). With the information the compensation controller has at its disposal, it’s a small step to a variety of other end of life options, including shutting off at a set number of operating hours, going to an obviously dim mode that signals the need for replacement, but still keeps people from stumbling over a curb, or simply “phoning home” to advise that failure is imminent, and replacement needs to happen while the lights are still on (hmmm… wondering if it can monitor the capital budgets or inventory to choose the most convenient time for the notification?).

The idea of “phoning home” provides the entree to the whole idea of the lighting network, where two way communication is taking place. We recently had a chance to meet the folks from Synapse Wireless who have developed a very flexible, self-configuring wireless communications network that allows individual elements to communicate back to “home base”, either directly up to 2 miles for a simple node, or over extended distances by passing the communications seamlessly from one node to the next. The added cost of the communications chips and transceivers can currently get to about $5-10 per node, which in the context of several hundred dollars for a streetlight isn’t all that much. And as we know, the cost of technology is on a steadily decreasing curve for that kind of thing, so the idea should definitely have some legs. Transmission line communications are part of the current “smart grid” type of capabilities that are starting to be deployed, and while they have some major limitations when it comes to individual lighting nodes, there is always work being done to get around the next obstacle. I know I was amazed when my local electric cooperative (Texan for “power company when you’re not in a big enough city”) let me know that I could monitor my power consumption on a day to day basis online. Oh look, must have used the dryer a lot yesterday… it cost how much?

And the ideas certainly aren’t limited to the streets or refrigerator cases. In the last week, two new players aiming at the “intelligent facility lighting” arena made their presence known. Redwood Systems introduced their company and technology approach, which in its simplest form, removes the AC-to-DC and certain control components from the luminaires, and moves them back upstream to provide centralized power conversion, command and control. The idea is that it will enable data gathering about all aspects of the luminaires and the usage patterns and allow more economy of scale by eliminating redundant power and control componentry, as well as provide almost limitless flexibility in the integration of the facility lighting as part of a fully intelligent building-wide, energy management “system”. They are not providing the luminaires, but are instead working on establishing key partnerships with luminaire providers and lighting companies who would offer the DC-only luminaires. Their technology overview describes the ability to control 64 fixtures on a single DC power feed, which admittedly creates a little head scratching. One would expect a standard office luminaire to produce something around 1000 lumens, which currently requires at least 10 watts. Dividing the LEDs up to allow something like a 12V DC input, you’re looking at around 1A per fixture (or .5A for a 24V input), which can add up to a lot of amperage on a wire. Even at 48V, 64 fixtures would represent 15 or so amps, which doesn’t add up to cheap wire. (We’re giving them a call to clarify this morning, so keep an eye on a subsequent headline “Updated” note if I missed something). Assuming that the wire-cost challenges are overcome, using power rail systems for instance, the idea of treating the lighting as a network is a really interesting one.

The other new arrival in the arena is a company called Digital Lumens, who made their actual product announcement. They combine a ZigBee wireless protocol with motion sensors and other data to precisely manage the building wide network of high- or mid-bay luminaires that they offer. We’ve always been proponents of finding the best niches that really take advantage of the technology, and they have done exactly that by making the refrigerated warehouse their poster-child application. Cold environment, high shelves, narrow aisles. It applies nearly equally to more conventional warehousing, but LEDs do love cooler environments and have plenty of lumens to do the job when you can narrow their beam angle to hit those aisles spot on. No one needs to light the top of the shelving, just the sides, and in a warehouse, you don’t need to light it when no one is there. The incumbent technologies had a hard time being both efficient, and quick to turn on and off, so Digital Lumens’ claim for their pilot customers are a credible 90% energy savings. And it’s not because of an efficiency advantage at the source (LED vs. fluorescent or HID bulb), but rather due to being able to better control where the photons go, and when they go there.

All the ideas are good, and I believe this is just the beginning of the next wave in LED lighting: Make solid state lighting smarter so that the currently-higher acquisition costs are easily offset by the real-world, facility-wide energy savings by using a little less energy to make the light, and a lot less to get it where it needs to be, when it needs to be there.

Rubio’s, the San Diego healthy fast food chain that popularized fish tacos, is introducing a new restaurant design in its fifth outlet in San Francisco that includes eco-friendly features such as counter tops and panels made from a recycled material called marmoleum, an open kitchen, and LED lighting that uses less energy.
