[♛ FreemeGB] ASTROLUX FT03 XHP50.2 (3V) 4300lm 735m 26650/ 21700/ 18650 Flashlight - SHIPPED!

You can’t really compare a Boost driver to a FET driver. The Boost drivers in those 70.2 really don’t get up 4300 lumens, they are typically closer to 3500-3600 lumen at most due to the limits of the Boost driver. I have not seen the M3 tested, but about 45 to 50 watts seems to be the drivers limiting factor (for a high quality boost driver design). Not all manufacturers build the highest quality drivers or max out the output.

This 3v 50.2 is only limited by the led and battery (basically). Bare 50.2’s powered by power supplies have been measured at 5,000 and even close to 6,000 lumen. Once you put it in a flashlight with all it’s optical losses in the reflector and lens plus electrical losses in the springs, driver and battery I think 4,300 lumen is definitely possible. Output will vary with the battery you choose, so an older model 26650 might not produce the highest output, but a high drain unit should.

It will probably need to pull around 16+ amps. It might hit 4300 lumen at a bit less amps, but there are a lot of variables specific to the FT03 design. We would need to wait for it to be tested and measured by a few BLF members to know it’s true output for sure.

It’l need about 14A to put out 4300 lumen

Running an xhp70.2 at lower currents is just cheaper/easier driver wise, they can still claim it’s an xhp70.2 (china likes bigger numbers) and the increase in visual brightness to running it at higher amps isn’t that big compared to the extra heat.

They’ll probably have a different corona but the FT03 (at least the first batch) has a smooth but not really smooth reflector which might help get rid of it

Thanks pal!

I need hot spot and/or beem shot for CW and how well it use black littokalla battery. I have bought too many so now I need more flashlights :partying_face: :person_facepalming:

Interested in the xhp50 version
Thankyou
