[sdiy] In the Dark

[Amos]

This is true... the half-life of EL brightness is on the order of 10k or 20k
hours if driven at maximum power, from what I remember. An unfortunate
limitation.

Perhaps there will one day come to be some sort of bioluminescent panel
lighting technology or "thin-plasma" display that will overcome this
obstacle & be available in lots of pretty colours...
