(pictures at end)
I have a 2x cr123 K2 luxeon lamp called palmblaze. 1 month ago I bought rechargable 3.7v batteries. They worked fine but lately there was a small problem that yesterday came again and wont go away.
This lamp has 3 operation modes, 1 is full power and 2 is half power and third is blinking. The problem is this: Total output of the lamp on full power is now only about 1/10th of what it should be. I have tested this with 2 different fully charged rechargables and with new normal cr123´s. There is a problem somewhere in the lamp and its not as bright as it used to be.
I had this problem for some time 1 week ago and this lamp went sometimes on full power and then it flickered. It was turned on that whole time. Then when I put normal cr 123's and after I let the lamp rest for 5 minutes, it worked normally. I first thought that this is a contact problem and the back screw was loose, and the batteries didnt give good contact. But just a few days ago I was in the forest with my friend and I used this with no problem with rcr123's. I used 4 batteries and there was no problem
My theory is that the DC DC converter is broken somehow because it couldn't handle the higher voltage. I know the lamp itself isnt broken because I taped 2x cr123 and took wires outta them (plus and minus) and I put them directly to the lamp and it flashed very brightly.
I was thiking if I remove the whole circuitry thing from the aluminium case, I could make it so that it bypasses the DCDC thing and goes like normally when I press the on switch.
Someone who knows how these things have usually been made, can you tell from what end should I try to push the circuitry out from the tube? Do you think its glued somehow in some factory?
This lamp still works but its like as bright as a normal 1 piece of 50mw led.... And its not a low battery problem:<< Help someone please if you know.:candle:

lamp head removed:
thanks if someone knows
