Are there any differences in the driver compared to SST-40?

It should be the same driver since they are both 3v leds. There is no need for a change, but it would be nice to get confirmation from the factory.

Just curious, the Convoy M3 with XHP70.2 is rated at 4300 lumens. Many compact sized flashlights with XHP70.2 have something like 3500-4000 lumens only.

Does the 3v XHP50.2 really go up to 4300 lumens? How many Amps will it need to pull to reach that 4300 lumens?


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.

Based on the Convoy L6 70.2 smooth reflector is it safe to assume the FT03 70.2 should be around 2200-2400 lumens with 400-500 meters of throw?

I’m also assuming we’re looking at an extremely fast turbo step down due to the very small amount of heat sinking/thermal mass?

The SST-40 already does that amount of lumens with significantly more throw than the XHP70.2 would have so that would be rather pointless.

I’m guessing 3800-4200 lumen, which again is kinda pointless unless you want a larger hotspot in my opinion since the 3v XHP50.2 can reach the same output with the original driver and will have more throw due to being a smaller emitter.

Should be a TA design driver, so I would expect high oerf FET.

Just curious, the Convoy M3 with XHP70.2 is rated at 4300 lumens. Many compact sized flashlights with XHP70.2 have something like 3500-4000 lumens only.

Does the 3v XHP50.2 really go up to 4300 lumens? How many Amps will it need to pull to reach that 4300 lumens?

Also, 5700K and 6500K tints for XHP50.2 = I wonder if they will have the same characteristic of cool hotspot and warmer corona (although the reflector head of the FT03 is big, so it may not be that noticeable for this size flashlight?)

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

Freeme can you please send me a code i want a XHP50.2 FT03

I put a XHP50.2 into my FT03 its so much fun i got 4200 startup lumens and it sat at like 3950 for a bit it does heat up heaps quick. My lux reading was 174kcd that was teken from an average of 3 test at 5m and my LED isn’t even centered that great. Slice the dome you will be laughing!
Such a fun light.

Ill return this one to my stock SST40 with the sliced dome cause that has its place also.
