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.
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.
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.
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…
Those 2 little mosfets should deliver more power than that, I’ve used them on 10mm drivers and had at least 3A even from a 10440 cell, up to 5A from an 18650…. and that’s just one of those FET’s. Surely we can easily piggyback a better driver onto that big board and get some serious output out of the thing… Should be able to get a real 1600 lumens from an XP-L pretty easily. Even a de-domed XP-G2 in the 5-5.5A range should rock in that big reflector. Hate seeing that massive flat bottom though. Sure poses issues, surmountable but unnecessary if it was made a little different to begin with.
