Baked / Heat Colored Convoy Pictures

Ok, it is not my convoy light, but that was with a reason, i was afraid that i might destroy it. so after reading all this i thought, Lets do it!

I disassembled some unbranded cree Q5 led light and put it in the oven @275 deg. C. For approx 30 minutes

Look at the result! Beautiful! Nice gold/copper color.
Assembling went ok, everything went smooth, until i tried to remove the batteries…
Ahh, the horror!

Lucky me, that i did not try out my convoy!

What did i do wrong? I forgot to lubricate because i was to enthousiastic! Would that be the only thing?

Since all threads felt smooth during assembly i did feel confident that it would be perfect!

Well, now i know how to do it and not to do it, lets call it gathering experience
