Well, you can still resistor mod it without going full direct drive. Although you will be “limited” to around ~7-8A, which is about perfect for most situations honestly.
The XHP70.2 should give a bit more output all else being the same and quite a bit more efficient wile doing it vs the last gen xhp70.
Interesting, high price and sad it is a 3B instead of a 3D but interesting for sure. What is the obsession with the B and C tints? It seems to be way to hard to find the A and D tints.
Correct. I have the XHP-50 Armytek Viking Pro and you almost can’t see the donut hole. With proper focus, this should be easy to correct—much more now with the .2 versions of these powerhouses!!!
Got a XHP70.2 today - 5000K P2 3B. Has anyone else rcv'd one yet? Debating where to put it. I'd like to try it in the Convoy L6 I have the TA driver in with the SMI reflector, or would also like to try it the MT07, but don't have a custom driver in it, but do have it resistor modded.
A member sent it to me from overseas, along with a SinkPAD. I'll post some pics.
We don’t have a test of the 70.2 to know for sure but we can assume it is at least the same improvement as the 50.2. In which case we can figure it has a Vf of over 1V lower then the old 70.
Seeing as the old 70 could pull 12A a full 1V lower Vf could easily see these 70.2’s pulling upwards of 15-20A+ depending on the cells used. Even if that didn’t pop it you can bet it won’t be making peak lumens up there. I figure it should be around 10A for max lumens, so you want a fair amount of resistance to drop the power that much.
End point is that it running it in DD with low resistance is not a wise idea.
