40 Percent Cheaper LED Light Bulbs Developed

Quanta-18-2TEternaleds, Inc., a company located in Los Angeles, which specialized in LED technology has developed a new set of LED light bulbs, the first of their kind to use a cooling technology which makes them 40 percent cheaper and that can be paid back in less than 2 years.

Although the advantages of LED lightning over the conventional incandescent light bulbs are very obvious and clear for most, the LED lights are still too expensive to fully replace the old system. And with the recent ban from the European Union on the manufacture and import of 100 Watt incandescent light, a more effective and environmentally-friendly solution is needed. LED lights have an efficiency of 80%, meaning that 80% of the energy used is transformed into light, in comparison with only 20% for the incandescent light.

But LED are very heat sensitive and they aren’t so good at spreading the light in all directions, as the common light bulb does. They also don’t pay themselves in less than 3 or 4 years of time. This is where Eternaleds made some improvement. The models from the Quanta Series, more specifically the -9 (it needs 9W to operate as a 50W incandescent light)  and Quanta-18 (18W for a 100W light bulb) have been designed in such a way that it increases the surface area and air flow, in the same time operating with 40% less metal, making them much lighter, performing overall better and remaining cooler. Because of its narrow angle at which it casts light, it is important to know where LED are most efficient, for example when used as spot lights.

With a much greater lifespan than the old fashion incandescent light, over 35,000 hours (that is almost 4 years) and now with a price cut to half, it is clear signal that this technology has a bright future.

    Except, 35,000 hours is about 4 years……

    You are right sir, thanks for the remark. It also seemed to me that the number was to high, but i didnt bother checking the calculation twice. I made the correction.

    I have switched most of my home lighting over to led bulbs.I use bulbs with a total of 48bright white leds purchased from http://www.dealextreme.com/products.dx/category.907~r.30061725
    The 48led bulb costs about 5$ (w/free shipping too) in quantities of 3 or more and has a rated lifespan of 50,000 hours. They run cool to the touch and give out a good bit of light.Though to be honest they work best as a reading lamp or spotlight rather than as general flood type lighting.But 3 or 4 of these WILL produce enough spread to simulate the light produced by a 100Watt incandescent.Singly they provide sufficient light for comfortable reading as a directed light source.And they use less than 2 1/2 watts to put out this much light.The 9led bulb is perfect as a refrigerator light and also has a 50,000 hour lifespan for a bit over 3$ each.I highly recommend switching to leds for anyone whose electric bill is getting out of hand and also for those hard to reach sockets such as in cathedral type ceilings where you would need a full size ladder to reach them.Put one of these babies in there and let your GRANDCHILDREN replace it when it finally burns out.

    Generally I’d just like to say that what is needed is a new outlook on lighting. We tend to build out houses around few lightsources, and they are mostly floodlights. We need to change that to accomodate spot lighting, as it is simply so much more energy efficient.

    Decorating with light is a stunning art, and this gives us all the perfect excuse to implement it. Sure, every room might need high power office lights in the ceiling for those times when you drop a needle or a contact lense, but for every day use what should be active is a series of spotlights lighting up just selected parts of the room, such as your reading chair and various decorative things that you wish to accent. I also recommend having a soft lighting on the wall behind the tv to make your eyes less tired when you watch movies, but that’s up to taste.

    This will save us lots of money and maybe encourage a lot of people to start going green.

    One glaring error I see in this design is the stupidity of manufacturing and selling only whole assemblies. If only the LEDs burn out, why toss and repurchase the significant amount of technical metal in the form of the highly designed and manufactured heat dissipator? Replace just the LEDs, please, in a manner similar to car stop lamps (socket). Treat the heat dissipator and associated electronics as adapters, and just replace the LEDs. I’ve spent a career in power electronics, the heat dissipator contains power conversion devices, a function that can live much longer than 4 years. So, add a 75 cent socket to the whole assembly, and then add 75 cents to apply a mating base to an LED only capsule. This post constitutes public display of my invention.
