A little mod to a Trustfire TR-J10 - Finished. Beam shots in Post #1

Whoa, you turned a tame light into a monster. very nice mods.

I’d perhaps suggest more a monster fire breathing dragon.

looking forward to the beamshots

Finished, last shots in the OP and beam shots in post #1.

I’m sort of opposed to de-doming anything any more. Only because I have ruined every one I have tried. I will leave it to better modders.

Great thread man. Read every bit of it and enjoyed it!

I must say that after you went li-ion your mods are becoming quite insane. I love it :-D

Great work O-L.

Nice. Tail current of 8.6A x 4V x 2 cells = 68 watts - small wonder it gets warm. 8)
What kind of run time do you get on high?

I know the feeling :frowning: I’m 0 for 4 trying to de-dome MT-G2s. Mind you if the 90s are easy might have a go with one

Sunglasses are required! 8)

Awesome mod OL!

About 2 minutes before it gets so hot you can’t hold it. Don’t know the run time on high, since I feel it gets so hot, it needs to be lowered.

Nice!

Missed this one until now. Thanks for sharing this mod OL, the SST-90 on copper was not done yet, and in a great performing light, nice!

I just got a pretty good deal on one ($41), so I’m gonna try and mess with it a little and I’ll report back on how it goes!

I don’t find it too bad, the head gets really hot on high for a few minutes but the handle is not too bad. I run it mostly on medium and find that sufficient anyway, with high as a turbo mode. I love the big hotspot, and it throws like hell. Wonder how many lumens its putting out. I’m getting over 8 amps on 2 kk’s. It’s a beast. Glad I bought it. Thanks O-L.

I just picked up a TR-J10 and I’d like to soup it up like you did. How did you get the driver out? Mine has a brass ring holding down a white nylon disk which I presume is pressed up against the driver. There is a brass cap screwed into the center of the disk which covers (and compresses) a spring. There are no slots in the brass ring to unscrew it, so I assume it is press fitted. The ring does have a lip around the inside which I can slip a screwdriver under, but it doesn’t want to budge. Do I need to cut it out? Or is there at better way?

I couldn't get that darned brass ring out at all. I finally used a small chisel and broke the brass ring, so it would relieve pressure and then I pried it out. I replaced it with a home made copper ring.

EDIT: I could have beaten the driver out after taking out the led, but I didn't want to hurt the driver.

Dang! I wish I had your mad skills to make the replacement ring!

I don’t want to damage the driver either.

I’m wondering if I could just use a 1-1/4 retaining ring ilo a press-fit ring. Hmmm. Home Depot says I can buy one for a buck, I may have to try that.

OK, I ended up using a dremel and a chisel to cut through that brass ring. It wasn’t pretty. My driver has that same tiny R300 resistor that you have, so it must be factory. Do you remember what size resistor(s) you ended up adding?
