That’s a bit long (26mm longer), but otherwise pretty similar dimensions to the Lumintop GT3. Certainly much more compact than competitors. Quite heavy though.
10k+ lumens and 1400m throw in something pretty close to jacket-pocketable (if my GT3 is anything to go by) seems like it could be a really compelling light!
Another interesting competitor/comparison to this light will be actually carrying 2 lights. Like, you could carry a Emisar D18, and Lumintops own thor 1 or 2, and it would probably be less weight, and possibly less bulk than this light. Of course you don’t have both available at the same time like you do with this.
I think more like the proportions of this Fenix would be good.
If it was more like the Acebeam X80-GT or Manker MK34 II with lots of floody XHP50.2 LEDs with a LEP diameter more like the Thor II (or even bigger) then it could get more flood and throw.
It’d be less balanced though. Another possibility is having throwy LEDs (W2 or SFT40), so the switch from LED to LEP is less significant.
W2 and SST20W for the ‘flood’ emitters, maybe 12 of them, and smaller optics. ~45mm optic for the LEP. Specs would be much more impressive in my estimation.
I’ll probably buy this however the leds are configured because any combo like this will be useful for boating.
But, I wish it had narrow TIRs for the ‘flood’ LEDs and at least neutral tint (high CRI not required). Use the LEP from 1.4km to 600m, and then the LEDs from 600m to 200m.
I’ll keep dreaming! Or maybe, if the sizes are right I can mod for that.
TIRs are almost always preferred by me these days, so I’ll agree. Also, I did some very quick and dirty layout measurements, and a ~32mm LEP and 12* ~13mm LED optic with 5mm emitter hole could yield ~170kcd and 12k lumens with the W2 running 50A total (Vf would be ~3.2V). The same LEP with the bigger optic should yield ~750kcd.
I don’t know if the driver (resistance wise) can deliver that much more amperage. The prototype on your cells is only pushing ~20A it appears with an emitter Vf of ~3.25V.
I estimate then about 32A total, 4 per emitter. Vf around 3.4V. This would suggest a circuit resistance of 20mOhm assuming each vtc5a is about 15mOhm. Not bad, but maybe could be improved some. Are springs bypassed? What FET (s) does this driver use?
According to these assumptions, 8 * 50.2 should put out about 17k otf and 48A
This looks like an awesome light but with two separate light sources, I would expect to control them using two separate switches. Going through multiple click hoops to get what you want seems really cumbersome. The Fenix LR40R got it right in this regard.
