I don’t see it as being a problem. there is a smooth transition from PCB to the stud and the nipples of protected cells have no square edges or sharp corners.

will anyone be so kind as to mod it to death to unravel its full potential? :smiley:

I'll try. Hoping to max it out for throw. Once I get it and measure the lens, I'll probably order a custom UCLp. Thinking of a de-domed XP-L, but I'm working on de-domed XP-G2's. Unfortunately, I don't have the capability to do much in a custom heat sink, but we'll see. I'd rather keep the cells 4P - easier to works thing out with a stock driver. I'm thinking this is between a COURUI D01 and TK61 in reflector diameter. Of course a lot depends on the quality/shape of the reflector to get top #'s.

Great for something this big at a decent price though.


When you have it, please share the measures of lens and reflector :wink:

Many thanks

<—- willing to help in the heatsink department. Feel free to give me a holler. :wink:

I have 1”, 1 3/8”, 1 1/2” copper and a piece of 2 1/2” that’s 1 1/2” long in Tellurium if that helps. The big piece was for something that didn’t pan out. :wink:

Edit: Also got a couple of XP-G2 S2 OD if that helps…

Be prepared for the fight as Palight has habit of gluing their lights.

<—- got large strap wrenches, can help with that too. :slight_smile:

Yikes - maybe I'll just send it to Dale Smile. Hopefully I can get it Monday, work on it asap to find out - hoping....

I just bought one at TaoBao @ US$73. This light is very heavy! With 4 CaroNite 26650, it weight 1.464kg. Luckily it has no glue anywhere, hand removal is applicable. Compared to TK61, the reflector has the same diameter and depth, but the base seat on LED side has larger diameter. They have similar spot appearance, but due to bigger hole, larger gasket and LED sit lower, the BOSS1 has the ring shapes around the hot spot.

Stock Flashlight is around 700-800 lumens. TK61 is far brighter. May be due to the thin silver coated springs high resistant contact point. And the LED is aluminium base.

Will modify this to MT-G2 using 18x7135-350mah driver which designed for 3x xml by the brand of HONDS.

Excellent! Post some pics for us!

Thanks CWK, interesting news. The TK61 throw #'s are a bit all over the place, from maybe 550 kcd, 620 kcd, to as high as 740 kcd from vinh here. Hard to say what can be accomplished with this, but has many possibilities.

How about shaved XHP70? or maybe even XHP35-HI as an alternative to XPL-HI, for thighter beam!

I am using iPhone and could not find the appropriate link to set into this forum, but you can see some of the BOSS1 photos here:

Good pics, thanks. Any chance it could take any pictures with other common lights to compare size?

Nice collection of lights wkchin. B-)

Inset 20 mm for the star looks like, almost flat reflector - slight flare up at the hole. Looks like that big pill top may be a screw-in, like a COURUI.

That driver does not inspire confidence!
Presumably, center point contact on a driver pcb is if you want to use one 26650 cell in the center of the battery tube which is a bit strange since all cell are in parallel so you could use 1 or 2 or 3 or 4 cells anyway…

Driver is pretty simplistic - those 0 resistors are basically jumpers, so no restrictions coming out of the two FET's. Makes you wonder why there's no decent amps, if output is 700-800 lumens.

+1 nice taste in throwers :beer:

I like your throwers!

That driver was obviously designed to be simply a contact board for us to do driver mods. :slight_smile:
