dusty neurons seem to say that they wear out in several years? Is that
the case?
I think one site I saw was claiming 250 days of "useful" life at continuous
use and "normal" conditions. Lower power (and hence less glow) will improve
lifespan, and the stuff never actually burns out but does become dimmer over time.
(in other words for the application I had in mind I'd probably be looking at 7
hours per day use, so with some fiddling with the power [1] could expect about
3 years of life)
[1] I'm not sure whether running at lower voltage is key, or if it's changing
the frequency which changes the lifespan (or rather, how those two relate).
