Even without this development, we're already there for small lighting uses. LED Christmas light prices were pretty close to incandescent this year. I suspect in 2009 or 2010 they will reach parity, and incandescent Christmas lights will disappear. For general lighting however we still have a way to go. Even if the LEDs cost nothing, it is necessary to convert 120 VAC into something the LEDs can use, and also to heat sink them so they reach their rated lifetimes of 50,000 to 100,000 hours. Both of these things right now drive up the prices of LED lighting well past the point of incandescent or even CFLs. Granted, when looked at from a total life cycle point of view a $25 LED bulb easily pays for itself, but many consumers only buy based on initial purchase price. Still, I feel once we get the price of LED bulbs under $20, perhaps even under $10, and educate consumers about the money they'll save long term, then LED can compete with the alternatives. However, we're going to have to make a quality lamp for this price-one which is dimmable, available is the common color temperatures, lasts as long as advertised, and has little variation in tint between bulbs. Right now I see too many LED screw-in lamps which are cheap junk. I hope this doesn't give a bad name to LED. Note however that LED screw-in bulbs are only an interim solution. Longer term, it'll make more sense to sell purpose-built LED fixtures which are designed to last a lifetime without replacing lamps. For many reasons, screw-in lamps are a poor form factor which requires too many design compromises in terms of space, heat dissipation, etc.It would be very nice if LED lighting became cost effective for general use (i.e. cheaper than all the alternatives).
