Have a couple x5/x6 drivers from BG, and a couple lighted switches. Been waiting to find a host that will accept the lighted switch PCB, but no luck and got tired of waiting.
Went through my parts bin and found a few 219b’s a few Noctigon boards, a bunch of p60 pills and an OP p60 reflector. Soldered the Noctigon to the pill, reflowed the 219b to the Noctigon, and installed the driver. Did not work, not one bit. Visually, I could not find nothing wrong with it. Maybe 219b dont like the DTP pad on the noctigon, or maybe bad reflow? I dont know.
Took the driver out and looked at my shelf… Saw an old XinTD X3 sitting there, unloved. It had a decent driver in it, think it was the 4 mode qlite. Nice tint emitter. Put the X5 driver in it, and fired right up in moonlite.
I ignored doing an emitter or driver swap in the X3 because it just seemed like it would be a pain in the arse to work inside the head, but was surprisingly easy.
I had put a royal blue switch boot in it as soon as I got it, like all my lights that will take it. The switch boots have a shorter nub that the X3 came with. With the new UI, I felt the slop in the switch felt wrong, so set out to fix it. I found a mechanical pencil eraser that fit in the switch spacer hole perfect, kept trimming it down until it was a solid responsive feel. But at that time it was too short and didnt stay in the spacers hole securely. So I chopped up a black boot to fit, was too tight, so chopped just the nub out and same result as the eraser. Finally I tried the switch with out the plastic spacer ring, and perfection. Nice responsive feel with out being too sensitive to touch.
Another problem I had and fixed a while ago with this light was issues with using a 26650. I thought the 26650 was too long and pushing on the driver and causing shorts. turned out it was contacting the metal switch assembly. I had cut out a washer of sorts to fit around the brass negative contact, but isolate the switch assembly. Never had a problem with any of my 26650s again in it.
Love the options with this new driver. I have been sitting here for 30 mins or so trying to set thermal regulation. Just shut the light off and decided with the XML2, it does not need it in this host.
