The ESL looks promising - at least it doesn’t look like a dairy queen cone ;-)

I’ve noet read a good description of how it works - the conventional approach to making enough of an electron beam to excite phosphors is with several KV of high voltage, and that would seem to imply a potentially noisy (EMI-noisy) switching power supply. Anyone know?

5K volts are generated. The claims are that there are no X-Rays or EM interference generated.

Electron Stimulated Luminescence

I don't see how the light quality could be 'better' than CFLs, since both use phosphor stimulation to generate visible light. It all depends on the phosphor mix used.

Watching the lumen output of LED flashlights grow and grow over the last few years, my money is still on an affordable LED bulb coming out one day.
