This is untested yet besides the low resistor was tested. Guessing from what I have seen from other drivers with this 3 parallel different value resistor stack
.
The Low resistor measures 200 ohms, a higher value will make a lower low. I tried 470 ohms and thats to high a value with a shaved 3500k LH351D 90cri.
I have several different values of resistors on order to try to find my perfect low. I prefer a firefly low, just enough to see in pitch black darkness without tripping on stuff.
I took pics this time when I modded one of these Ti3’s to a cree XPG3 in photo red 645nm. XPGDPR-L1-0000-00F01

NW factory Ti3 on the left, shaved LH351D 3500k 90cri on the right. White balance set at 5000k.
The factory NW Ti3 has noticeable green around the cornea in person that doesn’t show so much in the pic.

White balance set to 4500k.

My pic doesn’t look anything like it does in person. The hotspot is a deep red fading into the spill which is less intense. The beam pattern looks just like original but the color is a deep red with a very intense deep red hotspot. My lumen tube reported 30 lumens using a eneloop pro but it looks way brighter than that. I was surpprised at just how bright it is using a 1.5v battery, maybe it has something to with the color and my eyes. I dont think anyone has tested a XPG3 photo red yet to know what its capable of. I purchased 3 red leds to try LH351H, XP-E2, and XP-G3. The XP-G3 has a larger die than the other two with a higher max current of 1.5 amps, so thats the one I decided to go with. Using a Li-ion in this light should be interesting with the right setup.
All the pics above where taken in low mode with the factory 200 ohm resistor.

These pics are just a reference, for one I’m no photographer, for two what you actually see in person can vary alot from a phone pic.
