[Review] Astrolux FT02 2250 Lumen Thrower

Okay, that’s good to know it can take the 50E.

Did you test the amp draw at lower battery voltage levels? It might go up, since it uses a boost driver.

are you sure its not the other way around? how does a lower Amp rating battery (50E) give more Amps then a higher Amp rating battery(40T)

Since the 50E has higher internal resistance than the 40T, at start up, the voltage under load will be lower.

Therefore, to keep 2250 lumens, the boost driver will pull more current from the 50E than the 40T.

so between 50E and 40T, which will have longer battery life in turbo?

Just tested 40T on turbo. Ran for 1 min. 30 sec. before ramping down. 20 seconds longer than 50E. I will use the 40T.

@scr79423, the 40T will have longer turbo battery life.

Swapped led and driver in mine. Did not like the short runtime in turbo or the dim output when it steps down. Posted info in 3v XHP50 thread.

I am experiencing what I would consider very high parasitic drain on this light, after about 1 week battery is dead, anyone else experiencing this ?

Never mind just read that this is normal for this light, checked with my vom and got 4.16 ma drain, so normal.

Nice review and beamshots!

A refreshing change to see a boost driver instead of a FET one. I personally don’t care much for 21700 batteries/lights. I hope astrolux integrates this design in 18650 and 26650 single cell lights soon.
