LED lighting is finally reaching mainstream. As the years have gone by, the prices have dropped and more appropriate bulbs for home use have started popping up. Now that GE is releasing 60W, 75W and 100W replacement LED bulbs within the next 18 months, there's no more saying that LED bulbs aren't ready to replace incandescents yet.
The new bulbs follow GE's release of a 40W replacement bulb last year. All models are dimmable and will have a lifespan of over 20 years based on three hours a day of use. The 13W bulb (60W replacement) will be available this November, while the 18W (75W replacement) and 27W (100W replacement) bulbs will follow by the end of 2012. The 60W bulb is the most popular incandescent bulb, so having an LED replacement ready for that brightness level is key to consumers making the switch.
All of the GE LED bulbs will come in a range of colors and shapes including bulbs suited for spot and flood lights, ceiling fans, candle and night lights and small and medium globes for lamps and other fixtures.

What's interesting to me is that the efficiency of these bulbs is far below what we'd once hoped. While they are dimmable, long-lived, and instant-on, it seems that this first generation of standard bulb replacements is no more efficient than the typical CFL.

i agree, very disappointing. I have a 23watt dimmable cfl that's 100watt equivalent. it cost 6$

What these press releases don't tell you is that these devices have substantial heat-sinks to dissipate the heat generated by the diode. A lot of electrical energy is still being converted into waste heat.

Don't be so negative guys, like any new product line these LED bulbs will get better and cheaper over the next few years. They already have one important advantage over CFLs in their lack of poison mercury.

The elimination of mercury is just by itself the reason to make the switch. Never mind the huge room for energy efficiency improvement!

This generation of LEDs might dissipate heat, but how is that relative to other light sources such as Halogen, Incandescent, CFL, etc at a 100w incandescent equivalent? Anybody want to make a chart comparing lifespan (hours), energy efficiency per lumen, toxicity of materials used, volume of typical product, and price (compare this in relation to history, 5-10 year increments).
provide links too, please.
I'd do this myself tonight, but I gotta get the kids to sleep. And the wife is ill.
I am just trying to get a clear picture of how things seem to be changing over time.

Yah!!! For LED lights!!! About time GE introduced more of their innovative products to the public. LED awesome and more durable than incandescent bulbs. If you work up the math, LEDS lights will not only last longer it will also save so much money in lighting your home.
I can only talk about my personal experience and I'm tired of turning on an incandescent bulb and it popping.... waste of money and energy hogs. Read an interesting article on www.solartown.com/learning/sol...they-shine that showed me more design possibilities with solar lights.
Rock on GE and LED Lights

Still they have to get better if the environmentis going to profit from it. Many of this bulb are turned into bulb waste on our landfils and not recykled.

I know most folks have their lights on for more then 3 hours per day...so the 20 year 'life span' is really closer to 5-8 years. Still, not bad. AND, if one goes out, you do not have to call in a haz-mat crew to dispose of the bulb like you do for CFLs.

I agree that they have to get a lot more efficient before I buy them regularly. The one place they would have a big advantage for me in in the outside front porch light which is the only place I don't get 7 to 9 years of life from my CFL'S. As far as the mercury, all bulbs in my house are CFL's and I have more mercury in my teeth than I have in all the bulbs combined.

Another advantage of LED Bulbs is that they do not suffer a reduced life span when switched on/off frequently. Lights in bathrooms/toilets may not be on as long but will be switched on/off more often. This also the same for PIR activated lights, which will be switched frequently. How many times can you switch a CFL on/off before it fails?
50W, 60W and 70W bulb replacements available from www.ledpolar.com/led-light-bulbs/ efficiency for these is about 54lm/W. Also the above bulb will give a beam angle of around 150deg to 120deg, but traditional filament light bulbs give a much wider beam angle of at least 270degrees. Though only a matter of time before LED bulb beam angle available similar to a traditional bulb.
