Rivalries. Controversy. Government intervention. The life of a light bulb isn't easy these days, and it looks like things are about to get even more complicated. While CFLs and LEDs may now be fighting it out to replace traditional incandescent light bulbs, Seattle-based Vu1 Corporation says it has developed a new type of bulb that's better than either of 'em, and could hit the market by mid-2010. Making use of ESL technology (or electron stimulated luminescence), the new bulbs seem to be the cure-all many folks have been looking for, with them promising to provide a more natural light than CFLs or LEDs, turn on as quickly as an incandescent bulb, and eliminate some of the pesky problems associated with CFLs (like their use of mercury). According to the company, they'll also be about as efficient as CFLs, although they will cost about $20 a pop to begin with, which Vu1 says is comparable to a dimmable CFL reflector bulb. Some bold claims to be sure -- claims made even bolder by the must-see "documentary" after the break.
