I’m really frustrated right now.
I’m finally getting to work on my L2, and the driver build went so smoothly I was practically dancing in my office. I tried dedoming and XM-L2 U3 by mixing a few methods, and the emitter came out incredibly clean. I get it all built turn it on, and it works perfectly. I pull the tail off and hook up my clamp meter to get a reading, tap the button to get to turbo, measure 5.25A and… pop. :rage:
So I assume the bond wires must have been invisibly damaged with my special dedome method. A bit annoying, but whatever. I reflow a new emitter, and just drop it in gas to let it go the old fashioned way. It comes out not perfect, but good enough. Work s great on the power supply, so I get to rebuilding the L2. I have a short somewhere and I can’t figure it out. 45min later it seems it’s finally good. I fire it up, it works great. Turbo is even brighter than before :laughing: So I take the tail off to see what I’m getting with the clamp, tap the button to get to turbo, measure 5.4A and… pop. :rage: :rage: :zipper_mouth_face:
I’ve never had this happen. Never. :weary:
I’m using a Basen cell with a Sir800dp for the first time. I haven’t bypassed the tail spring yet. I can only assume that the resistance of the tail spring kept it from popping in the light, then my thick wire I use with the clamp was just too much.
