Last EL panel I designed a supply for was three panels 30 inches BY 120 inches.
They are going strong and haven't lost much light yet, But is has only been a
year and they are only on for 6 hours a day. That is about 2,000 hours.


A good alternative to an EL panel would be an LED back light. I've
seen ones which were made of a woven plastic fiber optic sheet that
was illuminated by an LED. Life should be virtually unlimited.
Something like this might be a good replacement

White LED lifetime is not unlimited.

I probably wouldn't have come up with this, but yes, now that you
mention it, when I looked at ebay, they all seemed to give lifetime
figures, although ISTR something like 100,000 hours, which seems
like a lot. :-)
