Well I received my Trustfire F20 yesterday. It's a 5 mode! AND it has the "good" 14500 compatible driver! (Tested and verified.) The driver actually has very nicely spaced modes. The strobe is actually one of the best I've seen. It's a "medium" speed flash rather than the heart-attack super fast flash.
On AA NiMh (Energizer 2300mAh LSD @ 1.35v) it pulls:
High: 2.40A (settling down from about 2.55A)
Med: 1.16A
Low: 0.26A
(100%-50%-10% spacing)
I didn't test current draw with the 14500, but the light was way brighter! (The tailcap is AWFUL, and once it's back on you don't want to take it off again! I remove the head and change the battery from the front end.) This will make a nice pocket rocket with my XM-L U2 emitter swap!
Looking at the head of the light, it appears that I need to unscrew the pill out the back end of the head since I don't any way for the bezel to unscrew. Anyone confirm this?
Yeah I was surprised! Remember, this is a boost circuit, so that's not 2.4A to the XM-L. When I do the emitter swap I might measure the current to the LED.
I would sell the one Erik made me , it's time that someone else gets to enjoy this beauty. It has a five mode driver that goes from moonlight to 3.55 amps and has an XML T6 3C emitter . Due to the current draw it requires an 14500 LMR cell . It's in great condition .
$30 shipped (US) . $30 + shipping for international .
I have one I EDC also, it’s great for walking the dog. Mines a 1A tint U2 with a 2.8amp max powered by an Efest IMR 14500. My brother took my Nichia 219 one but I do have 5 more empty shells to build if I can get the trembling in my hands under control long enough to solder the pills together. I have to admit mines holding up a lot better than I thought it would considering the amount of use it has and the small switch. They really belt out a lot of light, easily equal to the UF-2100s I built.
Hey E1320! Long time no see. I built one with a T6 3C emitter and the KD 3A driver with moonlight low. It’s my most used light now. Love that moonlight low.
