✌ FREEME - ASTROLUX FT03 Mini OSRAM NM.1 510lm WRGB LED options USB-C 18650/ 18350 Flashlight - ALIVE

Ordered three with green light.
Thanks for this GB, freeme !

I wonder if this will start shipping now? Says 22nd on BG

Let double check with them this week.

6th of October now.

Green/green is Oct 16th

So much for dates. Mine has been sterilized and shipped this morn

Mine is now processing so that’s good.

Green beam shipped.

can I still get in on this price? green / green
Nevermind, green beam is GONE. wish I saw this before today, my fault.

tried out 3 beam colors:

Astrolux FT03-Mini Osram white

Astrolux FT03-Mini Osram green

Astrolux FT03-Mini Osram red

d_t_a, I hope your bedroom is not next to that street, with engines revving all the time. :-D

The nearer building on the right side is a business-process outsourcing “BPO” (ie. call center that caters to calls from around the world), so it’s basically awake 24 hours… (not seen in the video, upper floors are lighted at night)

Thank you! I was on the fence about the red, but now know im buying it! appreciate the video :+1:

Interested, thanks.

I actually wrote some comments in the Youtube description link for each.

Anyway, here are some comments:

Turbo and High mode differ, depending on which beam flashlight (I only had White, Green, Red).

Tailcap current on High ~3.3A ; Turbo ~4.3A (may not be that accurate: I didn’t use full-charged battery, because based on an initial test, the white one turns bluish on Turbo — see below)

FT03-Mini Osram green = the green beam looks quite bright, I would think a wee bit brighter than Osram white when on max.
(also has a noticeable green spill area)

FT03-Mini Osram white = if I use a full charged high-drain battery, then set to Turbo, the beam will turn bluish and actually decrease in brightness (ceiling bounce with lux meter). This means, Turbo is overheating the LED. I need to use a not-high-drain battery, and I didn’t use full charge battery so Turbo will be brighter than High.

[maybe someone can comment if 4.3A is too high tailcap current for the Osram NM1, at least on the FT03-Mini? I have tested a Manker U22 II, with the same Osram NM1 LED, and measured around 5A tailcap current on Max, but the Manker U22 II’s Osram NM1 LED does not turn bluish on Turbo; at least not like the FT03-Mini which obviously became bluish)

FT03-Mini Osram red = I didn’t detect brightness difference visually (or with lux meter) when set to High and Turbo. However, tailcap current does show that Turbo uses a higher current than High, and Turbo will notably get the flashlight a bit hotter. Looks like the ~4.3A vs ~3.3A on Osram Red does not give a noticeable brightness difference? (I didn’t notice it turn “bluish”, unlike on the Osram white.

(Osram red doesn’t seem to have a noticeable “red” spill area, unlike the “green” beam. (visually observing)

Sure.

Ooops, posted on the other FT03 mini - forgot this one exist for just the NM1's. Got the green on green in today.

Guess totally forgot it's a Astrolux/Mateminco UI with press&hold to turn OFF, no ramping..

I measured 5.2 amps at the tail on a older VapCell VTC5D, but only 4.2 amps on a 35E at 4.06V, so looks like amps will depend on the battery resistance but they probably have some amp limiting built in. The loss of the AUX LED's around the main LED is a big time disappointment. I'm glad a got a mini SST-4 with Anduril and the AUX LED's.

For some reason they put in a bigger spring in the NM1 version. Dunno why - it's squeezing the flat top 18650 pretty good because it's stiff.

Did some measurements of the green NM1 version. On a Samsung 25S at 4.17V, measured 5.4 amps at the tail, calibrated lumens: 840 at start, 798 at 30 secs. Throw taken at 5m: 201 kcd (897 meters).

Throw does a bit better than rated, plus the lumens is higher, as expected for a green. There was a couple fine threads/fibers near the LED - took them out, cleaned up the LED/MCPCB and inside the head area - has some dirt/dust in there. There's a small scratch inside the reflector near the base, but don't think that effects anything.

Overall it's pretty decent - UI works as documented on BG here. There's no mode/level memory, and you can only click output+, can't go down. But still it's got a decent moon, 4 levels, and a slightly brighter turbo.

The driver is different from the SST-40 version - at least the exposed pogo pin pads are aligned differently on the spring side. Haven't taken it apart yet - would want to run Anduril on it eventually.

Just reviewing the White NM1 now, I have no low drain batteries so I get the blue turbo that has less lumens than the high mode. Even with a 9A 18350.

Banggood recommend 30Q but they are no good for this light plus hold for off is a terrible UI decision.

I agree with the hold for off - wut a PITA. For the green LED version: 5.4 amps on a 25S at 4.17V, and 4.2 amps on a 35E at 4.06V. But the green LED has a higher Vf than the white NM1, so if they used the same driver and circuitry, not good.
