Red Sofirn SP10 Pro w 660nm Red LED

[jon_slider]

I bought an AA/14500 Anduril 2 light.
Preparing for camping season, dont want to attract bugs or ruin other peoples night vision, so I decided to swap in a red LED..

The Ramping UI works really well w Red LEDs..
Firefly low of less than 0.01 lumens

the lights are on sale (not affiliated)

Does red or other colors take a special driver?

> take a special driver?

no, Im just replacing the LH351d and reusing the mcpcb. No issues.

if I put a red LED in a 3 mode light, the modes dont stay the same at all

the red light mods Im doing to the SC21 Pro and SP10 Pro, retain the low modes and turbo too.. though I set a ceiling to about 130 lumens on AA (100/150).. for reasonable battery life, and thermally sustainable output.
