am i the only one who noticed,that after watching this video? you can click on OLD LUMENS video? I dont wanna reflow the way OL does in the vid… just nice to hear his voice and see his hands again…

Never tried it… some day I’ll give a de-dome mod a go.

Its a Samsung 18650 in a spring carrier with alligator clips… Is this needed for the circuit resistance? Would a lower resistance setup cook the LED?

Afaik, several members use the “hot dedome” method since it’s a much faster and chemical free way to do it.
