Judging by pics - definitely not Carclo, likely the one in the other Mankers.
XHP35 HI is much more efficient than XP-L HI. Especially at high currents. I expect such mod to turn this light from a good flooder to a great flooder (while it remains OK thrower at the same time).
Okay, so I’m assuming Vinh does not want to change the mcpcb or optics so hes just going to swap emitters and drivers.
I assumed he would swap more parts to get a really big output. He’s usually pretty extreme like that. He seems to be using a conservative approach here.
I’m a big fan of Manker TIR.
4 LEDs in a 22 mm diameter is a lot. But more importantly - it can actually reasonably collimate them, competing with 20% larger Carclo. If I’m not mistaken, Manker actually wins that competition.
I’m a big fan of XHP35 HI.
Lots of output in a tiny space. And good efficiency. And good tints. And good throw as well. I do have some gripes, I believe it could be significantly improved, but it is great as it is already.
I find the combination of both awesome.
Actually the first time I saw them together was in a mock-up of Vinh’s BLF GT. Which had more than 2 TIRs. I fell in love immediately….not in that GT, but in the TIR+LED set.
It would be hard to fit anything more powerful in that space, regardless of how extreme you are. Unless one was to make a mule.
So yes, it may not be a hard mod (depending on the driver). But I believe it will be a well-working one.
