[Review] Astrolux FT02 2250 Lumen Thrower

I strongly suggest you use the best discount code you can find. This is just the one I’m passing along, if you don’t have another.

Would output benefit from say a 21700 30T or is that overkill?

No, it wouldn’t.

GREAT review! :+1:

What is the measured intensity of this FT02 ?

Was your light in CW or NW ? Nice review. Oooops never mind I do see it was CW now. Thanks

How many amps does it pull on max?

Which 21700 battery do you suggest, maybe Samsung INR21700-40T 4000mAh - 35A

With Samsung INR21700-50E 5000mAh - 10A probably will not get a maximum output?

It should be able to get maximum output with 50E as well.

I’d go with the 40T. It will pull more than 10A on turbo. You might get away with the 50E for short periods of time, but since this uses a boost driver, the voltage sag of the 50E will cause it to draw even more current.

Mine pulls 10 amps at tail cap with 50E and 9.5 amps with 40T. Drops out of turbo at about 70 seconds to 3.5 amps at tail cap. (cheap meter with 14 gauge wires). I would like to have a lower turbo mode. Catapult V6 runs for 3 min. on turbo at lower amps.

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.
