A company called Vu1 looks to have done the needful and taken a fresh look at energy-efficient lighting with a technology called ESL, or Electro-Stimulated Luminescence. This technology works by sending electricity through a phosphor coating on the inside of a seemingly normal glass bulb.
The merits of this new bulb (supposedly available in September) are as follows:
- Light quality similar to halogen or incandescent
- Turn on instantly (no warm-up) and work with dimmers
- Do not use Mercury (as in CFLs)
- Manufacturing requires less energy than LED
- Produce 40 Lumens per Watt (Incandescent = 15L/w < ESL = 40L/w < CFL = 50L/w)

Very cool that there is another green light technology out there. Is there any information out about when and where these will be available for sale?
Thank you for the great post!

Honestly, I have not seen anything about this techology since writing this post, and I most definitely have not seen this product on store shelves. Here in California, there’s been a big push on CFLs, which are also available at my local grocery store 4/$1.99 (100w eq)…If they don’t hurry up with production/marketing, their opportunity may pass.
