Yeah, once they realize that GaAs contains arsenic, we'll be sitting in 
the dark here in the EU in a few years. Lightbulbs banned, Fluorescent 
Lamps contain dangerous mercury, and LEDs contain arsenic. I guess 
candles are bad due to CO2...

I think we could maybe replace vactrols by NTCs driven by Peltier 
elements. :-P

Cheers,
