SingFire SF-348

singfire sf 348


SingFire SF-348 is a must have light, it is tiny, lightweight, good quality stainless steel body, I have the this one for over a year it has only a few tiny scratches and thats it, still shiny and no deterioration at all. It has a real glass lens, perfect aluminum reflector, quality leds inside, stable reliable driver (have had over 10 of this light gifted some to friends, and never heard a driver failure) and a SS clip. For all these feautures it's price is amazing. It will also work with 10440 Li-Ion but I do not suggest Li-Ion with this light, single / high mode only.

Current measurements:

I measured different current draws with AAA NiMH battery, the switch is limiting current to ~ 0.9 - 0.85 Amps, without switch it draws ~ 1.35 1.4 A.

10440 Liion at 3.86V without switch it draws 0.75 A

  • Single mode (For me, if it had a low mode 1 - 3 lumens and no PWM, it would be the best light ever.)
