It is strange, as carbon arcs, used to be very strong. But this is still produces a lot of dangerous UV radiation.

When I was much younger then I am now in the 50s these 'health ' lamps were common, now you may be lucky to see one at a boot sale and would not want to try it out without checking the electrics, I remember these would have an element like an old electric fire to give out IR while the arc gave UV you would of been advised to wear dark glasses, arc lighting goes back to Humphrey Davy and the Royal Institute where he installed a gigantic battery to run his arc lights. Sorry if spelling is bad this is due to the fact I can hardly see due to cataract which I have the op later this month.....peter.....nice to see that Y/Tube
