Correct, the wire makes it go direct drive, there is no sense resistor in your case. If you instead go with an actual sense resistor then it will regulate the current instead of direct driving the LED.
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.
