Added a Nichia 219C D240 4000K 90CRI to my Utorch UT01. It was purchased with an XP-L 1A 6500K which is way too cool white for me.
Mod was fairly easy too:
- Unscrew the bezel and you have loose front glass/oring
- Unscrew the reflector which is threaded to the inside of the body tube
- Take the centering ring and set it aside so you dont lose it (itâs important)
- You can either unsolder the LED wires now or lift the pcb from its base and do it while the pcb is suspended
- The LED pcb is not screwed down or anything it only had some thermal paste under it, you can work it out with tweezers from the flat edges and/or the wire holes if you are careful
- I cleaned off the paste and reflowed on the stove top. The pcb isnt clearly marked but the anode/positive side is the same side as the positive LED wire mark and the solder they used seemed to be some leaded low(er) heat stuff so it wasnât too hard to work with
- Resolder LED wires and
tryto stuff them back through the holes. I only got one side completely back in. The other side I folded over and ran the extra along the edge of the PCB leaving room for the centering ring since there is a good size gap between the reflector base and the pcb/body tube. - Centering ring back on > screw reflector back and re-center everything with the last half turn since the pcb is floating on thermal goo > oring > glass > bezel
