Philips' LED Lightbulb Uses 17-watts as 75-watt Replacement

As much as we love the warm glow of incandescent lightbulbs, their days are numbered as we have more energy-efficient methods of creating light. CFL may be the popular solution now, but the real future may be in light-emitting diodes.

Royal Philips Electronics is showing EnduraLED A21 17-watt light bulb at the Lightfair International tradeshow this week, which is designed to replace a 75-watt incandescent bulb.

Thanks to LED's properties, this 17-watt can replace the output of a 75-watt while reducing energy consumption by 80 percent and lasting 25 times longer.

The EnduraLED A21 17-watt, which uses the company's high-power, next-generation Luxeon LEDs, has a color temperature of 2700k, a color rendering index (CRI) of 80, and a rated life of 25,000 hours. The new bulb will be submitted to ENERGY STAR in the coming months for qualification testing.

Philips estimates that about 90 million 75-watt incandescent light bulbs are sold annually in the United States. Switching to this LED replacement has the potential to reduce energy use by 5,220 megawatts of electricity, a cost savings of approximately $630,000,000 annually. According to Philips estimates, switching to the EnduraLED 21 17-watt could also eliminate 3,255,205 million metric tons of carbon emissions annually, or the equivalent of removing nearly one million cars from the road.

Over its lifespan, the EnduraLED A21 17-watt could save a business or household about $160 per bulb. The real barrier to this cool lighting technology to really gain any acceptance in the household is the price, which is expected to be in the range of $40 - $45 when it goes on sale in the fourth quarter of 2011.

    The always problematic, "Why get this when there's a cheaper priced model for me?"
    It's a great step down in wattage consumption, but when you spend 500$+ just to replace 10 lightbulbs it'll seem to be a hard hit on most people.

    That's always the catch; it always costs more than what they're replacing, so only very few people would bother buying it. I'm also willing to bet that you'll need a special socket, or socket wattage to safely hold the bulb.

    I like these far better:

    $30 each, sometimes one day sales less than that.
    only 7 watts. I have five so far in the house.

    In theory, the price is not that bad for a light that stands a chance of outliving its owner. However, prices on these will drop as production, sales, and efficiency go up. This is not much more efficient than a CFL that costs far less. Its primary advantage over CFL is its lifetime.

    That said, I would not run out and buy a bunch of these for my home. Most of my lights are already daylight CFLs, and they last a long time.

    No. To all of your points.

    - Cost? If you take into account energy saving and the longer lifespan, the total cost of ownership is lower for LED's. Besides, they keep dropping in price. If you have half a brain, you look at what a product will cost you per year rather than upfront.

    - Special socket? Not anymore, modern LED's use the same screw-in design that outdated lightbulbs use. Several brand offer drop-in replacement LED's already. On the other hand, I don't see why they should maintain that design for new homes: LED's can use smaller, prettier sockets too if needed.

    Gotta wait a few years, just like when CFL bulbs came around.

    Anyone knows whatever happened to VU1 ESL lights? Anyone actually tried it or reviews etc? It sounded pretty good on paper : http://www.vu1corporation.com/about/

    I hate that warm yellow glow of light bulbs. i much prefer the cold white light.

    OK, so how many people know that when CFL's fail, they EXPLODE. It's all in the mercury and stepping up the voltage yadda yadaa...Yeah... I don't like them much. In fact, many major home insurance policies have a part that say if you have cfl's installed, they won't cover your house being burned down. Lots of local agents don't know this until they do paperwork and there's a simple question for it, and tada! not covered. I'm being honest and not out to bash CFL's since I love lower electric bills, but they are honestly dangerous and very specific to where you should use them(it requires venting at the base where they get hot, unlike typical bulbs where the heat is in the filiment near typical openings), just google it.

    Anyways. I use the bulb pictured above and two other LED bulbs in my house. They are in the fixtures that are turned on the most. My wife loves lamps, so her favorite lamp to just have turned on all day (I try... honest) has one, as well as two overheads that have a tendancy to get left on..(rolls eyes). LED bulbs are worth it, just be reasonable and pick your most used lights.
