When there's articles about Gallium arsenide (GaAs) semiconductors, you get the same comments. "Arsenic is a poison!" Yes, we know. Are you cracking the chips open an licking the semiconductor wafers inside for their flavour? No? Then you have nothing to worry about. This is the same category of thing. There's micrograms of carbon nanotubes in these lights as a thin-film inside a very strong ceramic casing. Unless you're smashing the thing open and then scraping the surface so you can snort it with a straw like it's cocaine, you'll be fine.
