    WOW! What a buy! And subsidized by American taxpayers to the tune of $10million. We should all run out and stock up to re-bulb our houses and ???save mother earth??? so they say.

    Prices will come down as they always do when new technologies begin to mature. When they do, I certainly won't be pining for the days when our light bulbs wasted most of their energy in the form of heat. LED light bulbs all the way, though I'm not going to be an early adopter.

    Somehow I think the era of the compact fluorescent will be short. We'll all have LED bulbs in a few years, and they won't be outrageously expensive. I just bought some 1W LEDs on eBay, and I paid $28 for 50 of them. Here's one LED shining on 3 others sitting on the all-the-way-from-China package:

    Each of these LEDs is attached to a "star" heatsink, and they can be operated at full brightness for a while with just air cooling, but I think for sustained operation I'll need to put them on a larger piece of metal.

    This is essentially a blue LED array that converts the blue to yellow via the phosphor coating--it provides a pleasing warm color--also the phosphor emits in all directions so that it acts more like an incandescent lamp.

    White LEDs use the same technique--if you look through the lens, you can see the yellow phosphor.

    Phillips LED bulb (1 for 50$):
    • Estimated Yearly Energy Cost: $1.20 (Based on 3 hrs/day, 11¢/kWh. Costs depend on rates and use.)
    • Life: 27.4 years (Based on 3 hrs/day)
    versus
    Phillips 60w incandescent 16 pack (16 for 4$)

    • Estimated yearly energy cost: $7.23 (Based on 3 hrs/day, 11c/kwh. Cost depends on rates and use.)
    • Life hours: 1,000 hours
    So the incandescents work for .91 years. That will get you 14.6 years with all 16, working out to 105.64$ in energy cost, plus 4$ for the bulbs, so 110$.

    The LED bulb, in 14.6 years, will burn 17.52$ worth of energy, plus 50$ for the bulb, so 67.52$. Almost half the cost, then you get 13 more years out of it.

    Looks like a good investment to me. I would be interested to see the same math done, if the whole price of the bulb was passed to the consumer (minus subsidy), and also the math showing projected inflation & increase in energy costs over the next 27 years.
