i know what you mean about the specs, i was told by one place it was a 85-240v.. 10 volts was enough lolol...hmmm?
i'm finding as with most led stuff to back off a touch with the power and the heat problems half. like with the little one wat stuff, full power it wow! that singes, touch back a bit with the amps and you can touch them bare fingered..only 5-10 percent.(less light..obviously but getting that least bit of full bright seems the problem)
and i was thinking to use it as a torch at some time, think i payed 8 dollers with postage for the 30wat, and 2 quid for a 10wat that is warm white,3200k range, its very gentle to the eye at that, maybe not a good reading light though, unless closer to it, no serious white blaire back from it.
