Thanks Bob
The flashlight was from Ebay, perhaps there was a translation problem. At the advertised 13000 lumen rate, it is the brightest flashlight I have seen, whatever the actual rating. If you look into the light, you have spots for quite a while!
At any rate, I left the LED connected to the 12v ups battery and the 1w 100 ohm resistor in series for 3 hours. For extra measure, I put a strip of paper towel on the resistor.
After 3 hours, no scorching on the paper towel. and the LED was cool and very bright.
I suspect the LED may have had a voltage rating of 3v or so. At 100ohms and 1w, I think I'm ok.
Thanks for all of your insight.
