I have the Haikelite MT41, which seems basically the same as the newer HT50, just with CSLPM1 LEDs instead of the yinding 5050’s.
It’s an awesome light. Haikelite claimed 6000+ lumens and 1400m on it but according to tests I found it was ~5600 lumens and 1160-1200m throw. I totally believe the throw from my experience using it, but I suspect it’s closer to 5000 lumens as I don’t see 4x W2’s making over 5200. Still, around the same throw and as bright/brighter than an SBT-90.2 would do in a similar sized bezel, and with much better W2 tint and a bit less heat. I think I paid$50 for it used, and it was maybe ~$60-65 new.
The HT50 claims about the same as the MT41 - 6000 lumens and 1400m. Same 4x 18650 body. It probably similarly throws below that. If I remember right, I don’t think the yinding 5050’s out-throw W2, they just throw similarly with more lumens. So I’d expect it to be very similar to the MT41 but with significantly more lumens and a bigger hotspot.
The Haikelite lumen claims seem to be theoretical values calculated from the LEDs, and not OTF.
This HT50 Pro (which I can’t find for sale anywhere) seems like the same thing, but apparently moves to 3x 21700 which maybe provides the yinding 5050’s with more power? And that’s how they get those higher figures? According to this test which I know is of the “different” yinding 5050 without the metal plate (and I think the metal plate one performs better), I guess you could assume they’re thinking ~2000 lumens per LED which seems reasonable theoretically. I still doubt it will hit those higher spec, but maybe a bit more if they’re getting more power from the 3x21700s. I suspect the higher throw claim is coming almost entirely from the larger 76mm head.
I will note that the convoy 4x18650 flat top to button top adapter works perfectly in my MT41, so I’d assume it will work in the HT50, and there’s a good chance that the convoy 3x21700 adapter will work in the HT50 Pro.
I don’t know, but they do. The same could be said of Convoy, and some other brands like JinHeng.
My MT41 has great build quality, and performs very well. The switch is a little cheap feeling, the usb-c rubber flap isn’t the best I’ve seen but has never failed and works well, and there’s no electronic lockout, but overall it’s really nice. The rose gold color is nice.
The Yinding 5050 LED’s aren’t very expensive, which likely keeps costs down, and they’re clearly using a LOT of the same parts on a lot of their lights, so the only new component for this HT50 pro might be the reflector. Of course it’s just a FET driver too I’m sure.
