Convoy L2/L6 modding thread

Maybe I’m wrong about the XHP70.2 having less throw than the XHP70 at the same current. Anyone want to give some measured numbers? And this is not to say that I think the XHP70.2 will have bad throw; it will work fine in your L6.

Assuming my “26650 KeepPower 5200mAh Protected High Discharge” batteries regulate the amps to roughly 9.5A (going off the advertised max discharge rate) with the FET driver, would the XHP70.2 be reasonable in direct drive mode? I guess even if it isn’t, I can always just dim it some to get to a sustainable temperature.

What about the XHP70.2 causes less beam intensity? Seems like it is the same other than the smaller gap between “cells”. On the CREE data sheets I see 120 degrees for the viewing angle on the 70 compared to 125 degrees on the 70.2 . Is that what would cause the reduced intensity? What about if they are both dedomed?

Seems like for the same voltage I should get much better performance out of the 70.2 based off of the forward voltage charts in the data sheets.

I’ve got some experience in electronics, but a bunch of this is new to me, so I apologize for the more basic questions.

The reason I’m saying the XHP70.2 will have less beam intensity is because it is a new type of LED architecture from Cree which we have observed to have less throw in other LEDs. See here.
