I modded mine with a dedomed xpl and a amc7135 running about 3 amps. Didn’t really want to have any heat issues. I’m sure it would really throw at about 7 amps. I like it better with the xpl dedome than the xr-e, not enough lumens with xr-e. It will throw with a xr-e but the beam is so small it’s hard to spot any critters unless you shine it right at them. It’s laser like. With the xpl the beam increases in size compared to the xr-e but the xpl beam seems way more intense. 230 lumens versus 1200 lumens. You might try a xpl hi v3 or a dedomed xpl v6 in about the 5500k to 6500k range to allow for tint shift. I had tried a xpg in this light several years ago and didn’t like it, I guess it’s because the beam size increased with out a lot of lumen increase. I had changed it back to the xr-e until about a month ago when I tried the dedomed xpl and I like it the best.
