IE: is it a major change over from LED types? Cost is comparable, and usually not a driving issue considering= other factors, like: Bad: EL is about 4000 to 5000 hours to half brightness Good: EL is very even Good: EL is much lower power (best for battery operation) Good: EL can be very thin EL does not emit as much light, so you may not be able to tell if= it is on in a brightly lit room, but it will still be very= viewable in a dark location. The 5K hours can go a long way if you turn the EL off after a few= seconds of inactivity--this will also help on power= consumption. There are good, small EL inverters, check Sipex and SuperTex. Summary: for very compact low power applications, EL should be= considered, pretty much everything else ends up with LED= backlight.
