Ye gods, man. I just want to check my text messages, not melt the skin off my face.

#2 I was talking to a rep for Dual-Lite emergency lights the other day. They are not quite there yet for minimum ft-candles for LED emergency lights. LED emergency lights could allow emergency illumination in building spaces for many more hours on the same batteries that run incandescent emergency lights for 90 minutes now.

#3 Wake me up when they announce a production cost breakthrough. And $50 a bulb isn't what I consider a production cost breakthrough.

#4 Sorry for the silly question, but how long do these things last? Maybe $50 isn't too bad!

Existing incandescents have a lifetime of about 1000- 3000 hours of use. The high pressure sodium vapor lights go up to 40,000 hours. In theory an LED light ought to last practically forever but the company is aiming for lifetimes of 100,000 hours.

Regarding cost, the cost will probably be initially set as the maximum price that will enable the company to sell everything it produces - so it will start rather high - say $50. However, as they add more production capacity and their R&D costs are spread over more revenue, the price would go down.

I have my emergency light right on my keychain. :)
