FlashPilot, I’ve heard about the resister mod for the TN31, is there any detailed information on how to do the modd? And how much is gained by adding the resister? I just did my first dedomeing in gasoline and it worked perfect, so with the resister more and dedomeing the emitter I’ve heard will make it a beast, sounds great to me.
Resister modding the tn31 is beyond easy. Just take off the driver cover (3 screws) and place a solder blob in place of the below indicated resistors. The below pic is from this thread.
If you're lucky, you will get around 7 amps to the emitter. More likely you will get less due to resistance in various places in the light. I would advise that you check the place where the emitter base sits for flatness. My xml2 tn31 had a nipple lifting my base up in the center and no compensating thermal paste. It's a great time to do a dedome anyway. No reason to change the emitter base. You can't get one that good in the market.
