I like the concept, for me, I categorize this kind of light as “What was that noise outside” sorta light. It would sit at home or maybe go on a camping or fishing trip. A little too much size to be carrying around for extended periods, although the mass helps with the heat. I’m fine with a single cell, medium size reflector, side switch light. My wish list appears to have been answered with the Astrolux FT03 SBT90.2 that’s coming out. I just cancelled my Nightwatch NI40 because of the ongoing issues with the clicky/mode switching. The reflector of the Astrolux is about the size limit I would carry around in my pockets. (Cargo shorts) The 26650 size body calls to me because I really liked the feel/grip size of a C cell Maglight.

Doing what?

Lux_perpetua is Haikelite?? Or it look more alike ? Nevermind…

Have anyone try put this sbt90.2 to convoy L2? Does is fit? Just for a try with convoy driver…who know it will be much so low heat? Idk.

I’m just curious how the 20+ amp passing and where the heat will dissipated. I think most about current flow should be regulated constantly with rise with temperature. Or is there any better regulator out there for sbt90.2?


No no,haikelite is making almostly the same as Lux_perpetua showed us, 85mm head, 3*21700 batterry, type-c, fast charging and Andùril UI, pic below is raw material what the new light will be made from.

That all sounds real good, bout perfect actually, and HL tends to overuse alum in their lights which is a good thing for this LED. Just hope the finning is aggressive and the pill area beefed up.

HL host is super robust and good heat shedding with their fins. Looking forward to this especially considering it will have USB-C recharge instead of a proprietary charger.

Should blow away the FT03 in beefiness, runtime, throw. No comparison really - look'n forward to more details. I got an original MT07 engraved with my BLF name, from doing the original review. Now has a sliced XHP70.2, custom driver - it's a beast! This new SBT-90.2 sounds like it will be a very similar form factor - bout same head diameter, 4x18650 vs. 3x21700, etc.

HL just might produce the most exciting thrower since the GT. Fingers crossed that they can produce a reliable/stable driver at the +20A power levels, while incorporating large cooling fins where they are most needed.

Haikelite, if you’re reading, we want HUGE cooling fins around the shelf/pill area that extend up the length of the head. Don’t taper the fins to follow the head contour… leave them huge and deeply finned. A 1 piece head would help facilitate heat management. Id pay more for the added cost of the larger diameter aluminum and cost to machine the head from solid round stock, just as Olight once did with their large SR series lights.

I’ll second that!

Continued from post #31, I got the SBT90.2 working in the 1504. Results are not bad - I was able to do over 500 kcd, hitting a peak of about 540 kcd measured at 5 meters indoors. Measured 21.6 A max on a GOLISI but I'm using only 22 AWG LED wires on a SIR800DP based driver. Lumens was under 3,000 - low but expected low on a aspheric lens.

For comparison, in the same light with an old good dedomed XPG2 S4 2B I got 510 kcd.

I'm still not sure though the SBT90.2 is fully focused. When I hit the max at mechanical focus, the beam is still shrinking. It could be at max or close, just not sure. The light is staying fairly cool considering, but it's in a brass pill, and being a zoomie of course, the heat is somewhat hidden inside.

On a new Shockli 5500 from Neal, it hit 20 amps max - actually it seems to work as well, maybe better than the GOLISI, since the GOLISI seems to drop off fast. The Shockli tested at ~5800 mAh.

What are the advantages/drawbacks of an aspheric lens vs a smooth reflector?

Aspherics:

  • way less spill, really no spill if done right. This could be a big advantage for some uses, like in tactical situations, not blinding animals/people out of the hot spot AOI (Area Of Interest), not bothering neighbors, etc.
  • for me, way easier to mount a non-standard size LED - no worry bout the LED retainer ring fitted to the reflector, etc.
  • if it's an adjustable zoom, when the lens is drawn in, they tend to have a real nice consistent spill/flood, way better than TIR, reflectors, multi-LED's, etc.
  • of course there's a price: much less lumens in either full zoom out for throw, zoom in for flood. The flood setting is higher lumens.
  • Adjustable zoom aspherics are really two lights in one - a flooder and thrower
  • hot spot tends to mimic the shape of the LED, so hot spot is typically a square

I'm not sure what throws further given same head diameter - this 1504 is a 70 mm head diam and getting 500+ kcd - not sure how that compare with true thrower reflector lights. An FT03 is rated at 69.5 mm head diam, 875 meters, 190 kcd throw for the SST-40 model. Dedomed SST-40 should be close to 400 kcd, if these numbers are legit. I assume the throw #'s between aspherics and reflectors are close, depending on the quality of the lens or reflector.

Were the measurements taken at turn on or 30s?
Either way 500Kcd is pretty impressive. Hopefully the FT03 can hit those numbers. SST40 FT03 goes from 235 to 367 after dedome according to tm07. If it’s possible for Luminus to make an LED which outthrows the XHP35 HI/SST40 whilst putting out more than twice the light, I wonder what kind of performance they could get from a smaller version with half the output.

Lumens I'll do at turn on and 30s, but throw, 540 kcd is probably taken aggressively. I did do amps measurements first, and didn't take the highest reading asap - it's all about finding that peak, so sometimes it takes a few secs. This aspheric hot spot is like other aspherics - you got to hunt for it. For this LED/light at 5 m, the brightest spot seemed to be on the edge of the square - you can actually see it change. Like at 1-2 meters, it seems the hot spot is center, but then as you go further away, the edges get hot. Probably best to take it at 10+ meters. I still don't have a clear focused image of the LED surface so I don't think it's fully focused for the best #.

I purchased the Acebeam K30 GT from Andrew-Amanda.com
This torch is beautiful and I recommend it.
