A few weeks ago, I came across a press release from Philips announcing the first entry for the Department of Energy's Bright Tomorrow Lighting Prize (L Prize) -- full details on the rules can be found at http://www.lightingprize.org. The entry criteria for this competition is a replacement for the standard 60W incandescent light bulb that consumes less than 10W, provides a lifetime of 25,000 Hrs, and can work with dimmers down to 20% of full illumination.
This is a significant milestone, and will help to reduce energy consumption for general lighting in our homes and offices. Of course, one motivating factor is an award of $10 million, but more importantly there is the anticipation of huge government contracts not too far behind.
Why am I writing about this achievement?
Well, it is something that can really help most of us take a responsible approach to reducing our consumption of energy (electricity costs), while replacing the standard incandescent with something that has similar brightness, color rendering, and color temperature. In addition, this will be great for those who are sensitive to the subtle flicker of compact fluorescent light bulbs, CFLs, and others who simply enjoy the perceived warmth of the dependable incandescent.
However, what really caught my attention today is the realization that prize money is not yet allocated! Apparently, congress has not got around to setting aside the funding, so perhaps Philips, and the other companies expecting some reward, could be out a fair chunk of change. One estimate is that just the cost of the light bulbs submitted for evaluation by the DOE was as much as $0.5 million. This does not include all the years of research and development.
On another point, because the L prize rules require each entrant to commit to manufacturing the product, what is the expected retail price for the consumer? No doubt the LED light bulb will cost more to produce, compared to an incandescent, but I believe it should be priced less than a CFL once economies of scale are reached. The cost of the internal electronics are probably very similar, plus there is no need for a gas-filled glass tube to be used.
The only downside that I see is for residents of our colder regions. Many have come to accept, and embrace, the heating and comfort benefits of incandescent light bulbs. With the reduction in energy consumption for lighting, there will clearly be an incremental increase in energy consumption required for heating.
I guess it is all "swings and roundabouts" as usual.
