I've found an answer to my own question. 2-3 lumens per watt. But it is spread out over a large area. Does any one know of a photometric measurement which can predict the lumen output compared to an incandescent bulb? I understand that the self-induced phosphoresence is at a difference wavelength and frequency...I have noticed in personal experiments that the acquisition of EL at long ranges is much better than incandescent(almost 5 times better). Even with smoke, debris(dust), and fog it can be acquired as much as 3 times earlier than incandescent. Maybe the EL light is perceived(by the eye) differently than incandescent so the lumens do not ever matter!?!? Thanks...
My company has been looking into this product and a possibility of being a printing media for us to use. Thanks for the info it will be helpful in the future.
