I found a new one here (well new to me)
http://www.backlight4you.com/product_info.php/info/p849_EL-Panel-- blue-green--43mm-x-155mm--laminated.html
Anyone in europe, this may be your source for backlights, hope this
is useful to you with fading backlights, I've just ordered some
backlights here, will let you know how well these work.
