Hello,
my name is Benjamin and I'm interested in flashlights for a long time. I'm a member in a few forums about these for years and have a few and help friends to find a good solution for their needs to "fight" the darkness. Until now, I use only white LEDs (I prefer NW like the Nichia 219 or a "classic" XM-L2 T6 3B, copper base, 3,5 Ampere(for the XM-L2, the Nichia with 1,5A), powered by 1 x 18650 (for me the best combination between output and size). Of course I use also bigger flashlights powered by 3-4 x 18650, 3x XM-L2 LEDs, but they are to heavy for a edc.

2 months ago a friend asked for a nice flashlihgt and I ordered a usually T20 for him. Now come back and asked, if I could transform it into a 940NM IR flashlight, and the change shouldn't be exensive. This is the main reason, why I entered the forum, because I have never used a IR LED and at the moment I find only information, that they need much less voltage as a usaully LED.
For each LED I use a linear Nanjg 105 driver and with the numbers of 7135 chips I can control the max. Ampere. But each Cree LED I use can handle 3,5v and more. The IR LEDs I found have often only DC Forward Voltage (VF) 1,4-1,7V and I think, the Nanjg driver will harm those.
