So last night I tried to change LED on my stock BC40’s XM-L U2 to a XM-L2 T6 4C on 16mm Noctigon for better tint. However, the reflector base was too close to the wires so I ended up RE soldering a few times and I notice the head of the light was very warm/hot (I can still hold it). But the max is less than 50 lumens now vs 830 stock.
I put the stock LED back in, but still the same. Did the driver get damaged from the heat or the short when the reflector was touching the wires?
I can’t seem to get access to the driver either. No idea how it is being held in the head. Any ideas?
I hope not, when tighten the head i get around 50 lumen, when I loosen it only around 10 lumen. So the high low setting seems to work. Just that both high and low is no where near as bright as before.
Edit: If some know how to get the driver out is fine too. Anyone know?
Yeah, I was finally able to open the head using a pair of strap wrenches. Turns out I heated the wire a little too much and the other end of the wire that connect to the driver almost came off. It was barely connected. So I guess problem was that a small connection cannot handle higher current. I pull the wire a little and it came off.
Since I got the head apart, I figure I wanted to put a XHP70 in it using a buck driver. However, the pill is only around 18 mm, so I will have to cut the sinkpad a bit.
It won’t come out voluntarily, they used generous amount of glue, same with BC40SE, have one with destroyed LED (I didnt get the driver out, yet, not sure if I will).
