Very interesting light but with 3 or 4 accus much to big for my hands and to heavy.
This Head with one 21700 would be cool.

The good thing about the LR40R is that flood LEDs and long-range LEDs can be lit simultaneously or independently, Marauder 2 could only select one side alone lighting The size is a little larger than X10, but I think that it is suitable as EDC

The LR40R is 4*18650 too, right? I think this Lumintop will be about the same size as the Fenix and the Marauder.

Should be able to have them on independently or together too.

I like the idea of a single 21700 version of this, though it’d probably have to be quite big to be effective and worthwhile.

I do wonder how watertight it will be, the USB ports look like they are open to the environment. No flaps etc..
But maybe thats because it’s a prototype? Can’t imagine them making this light not watertight

Wow!
8x xhp50?! That is a lot of potential lumen in flood!

If they get into the Anduril 2-train on this, I’m hooked!
A properitairy UI could break this light.

The prototype has arrived! Charging some button tops now... I'll share initial impressions and info in a bit and a more thorough review soon. Let me know if you have any specific questions or things to test.

Wow!

UI and type of flood LEDs is interesting to know. Button tops only? No adapter plate for flats?

The LEP, like a Thor 3 or like an antman?… Smile

I think I’ve worked out the UI. I’ve started a review with details on the second post https://budgetlightforum.com/comment/1826242#comment-1826242

This one has XP-G3 LEDs but I’ve heard second hand that others may have XP-L or XHP50.2.

Yes to button tops only. There was no adaptor plate (like Convoy sell) in the box, though this is a pre-production prototype.

The LEP is somewhere between the Thor 3 and Ant man :-). I’ll take measurements later.

I’ve done some very quick and rough measurements. The XP-G3’s are hitting over 7000 lm and throw is around 500kcd (1400m). More details at the start of the thread.

The lens is glass!

The prototype is Lumintop’s own UI, which seems to work well. At least it’s not hold for off Smile

That’s what I thought too. You have to unscrew the tail cap to get to the ports, which are on the main body tube.

I’m not saying this is an ugly light per se, well maybe I am a little. But it does strike me as uninspired when compared to all the bolder and pretty slick looking bigger lights we’ve seen released lately. Seems interesting for sure, but the emitter options also seem to be uninspired considering they’re only looking to pump 7000 lumen. Not necessarily a huge fan of the LH351D’s or 219C, but I think those would be a great option for one of these. 4000k especially, regardless if there is a slight loss of output. Or maybe even the 219F Acebeam is using in the Rider RX.

I guess I’m just looking for ways to make this light more appealing, because right now it’s appealing to me, but not really.

To clarify, the 7000 lm was from 8A cells, so it may do more with high drain ones.

I should be getting some high drain cells early next week to test with.

I recorded 2 quick videos of the Lumintop Thor Pro:

I’ve also added a few more photos that Neal sent to the first post.

Can we get some rough measurements? How wide is the bezel?

That seems to me to be a crucial/very interesting bit of info for a light like this. The whole point/advantage of an LEP is that you get the same throw with something like the 40mm bezel of the thor 2 as you get with the 72mm bezel of the Noctigon K1 W1.

So putting an LEP module in the middle of a floodlight should mean it’s able to be smaller than competitors like the Fenix LR40R and Olight Marauder 2, while also throwing MUCH further. The Fenix and Olight both have ~80mm bezels, and in my mind for this to be a truly neat competitor, it should have closer to a ~65mm bezel.

The XP-G3 is a bit of a weird choice. XP-L HI or HD would definitely be better. 8x XHP50.2 or 8x SFT-40 would be truly awesome, and could put up super compelling flood numbers along with that sweet 1400m of LEP throw.

Here’s what the prototype measures:

  • Head diameter 67.0mm
  • Body diameter 51.1mm
  • Length 157mm

Rough numbers for the optic diameters:

  • LED 15mm
  • LEP 26mm

Weights

  • Without cells 644g
  • With cells 830g

I want this light! Ideally it would use 3 or 4 21700’s (no 18650’s ever again please, 21700’s are so much better and only slightly larger).

I think the options should be sft40 and xhp50, not xpg3 or xpl

Thanks for the measurements, dave1010!

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.

The LEP to LED optic ratio seems off.

The floody LED optics should be smaller and the LEP larger, imo

Yeah, I agree.

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.

Do you mean combining W2 and SST20 or triple channel?

It would be cool to switch between

  • High CRI warm flood light
  • Throw LED
  • LEP

Though that’d make 6 combinations if you could use them in pairs, which would be a complex UI.

No. Dual channel. Just giving the emitter options. High lumen or high cri, but both options giving best cd/lm in their class

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’ve re-tested with 4 high drain Sony VTC5A cells, which should push it to its limit.

It now hits 8375 lumens with the XP-G3 LEDs and the LEP, up from 7238 lumens, which is a 16% increase. A few more numbers on the second post.

I haven’t tested throw again but the LEP-only lumens didn’t change much.

Remember that this is still a prototype. The final version might be identical or could push 8 XHP50.2s over 20,000 lumens.

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 does this driver use?

According to these assumptions, 8 * 50.2 should put out about 17k otf and 48A

Mostly I use my lights in manners that need lots of juice, 4×21700 would be great.
Also, NW or 4000k would be great.

Thanks for the numbers. I’m trying to follow along, so I can work it out for other lights…

  • 8400 lm over 8 LEDs is 1050 lm each
  • 1050 lm plus a bit for losses takes 4A with a Vf of about 3.4V, according to https://budgetlightforum.com/node/48222
  • Resistance is Volts over Current, so total resistance is 3.4V/32A = 106mOhm
  • VTC5A is specced at 13mOhm (Mooch measured 18.6), so 15mOhm each is reasonable
  • 4 cells makes 60mOhm from the cells, leaving 46mOhm for the circuit.

Where have I gone wrong?

The springs aren’t bypassed with wire but there are smaller springs inside too.

I’ll take some more photos before trying to take it apart. I think the charging circuit needs to be removed to get to the springs.
