I followed Ma Sah1 to cut down my itp and pop in a 10280 from my Draco using these instructions https://www.candlepowerforums.com/threads/250746

and it looks to me like the light is brighter and wider beam than the Draco. Astounding.

Here's the pic btw. I did a purple version.

My question....
Is it safe to use this on high? Thermal runaway likely? Will it damage the battery? -is the C value to high for a 10280? will it damage the LED or my hand? I can live with the LED going poof (but would prefer it didn't ;-) but don't want a safety issue with the battery going poof.

I've ran it for about 5 mins on high and it does get hot.

I'm asking as I guess I don't fundamentally see how this is much different than a draco . As you can see its slightly larger.

FYI the mod took me about an hour.

Any thoughts?
The 10280 is rated at 180mah I believe. Not sure what the A3 current draw is on max. Is direct drive (which I assume it must be) too high for this little battery?

It should be fine.
I've let mine run for 10 minutes non stop in my hand just to test it out. It does get really hot. I have made several XPE key chain lights using 10280 direct drive. One has been on my keychain for 6 month now. The direct drive may get even more current than the regulated cut-down light & I haven't seen any of my 10280 light burn out yet.

Just curious, why did you grind off the ano on the tail? Started as an accident?

LOL, yes, I don't really have any tools to narrow one end, and widen the other. Believe it not but I used an angle grinder (10mm spinning disk used to cut metal / stone etc) to slim down the spring end. Once I had marked the end I figured best to make the rest match. LOL.

Have to say, its an amazing bright light and useful. Only drawback was getting the tail to stay in. I ended up using plumbers putty which seems to have done the trick now.

Thanks for the feedback, and original instructions.

If anyone else has any experience driving a 10280 hard I'd appreciate it.
