Can you upgrade mine that you modded with the new XPG2-S4?
This is not a simple LED upgrade. It's a complete new mod that involves all of the same work even if its just a LED swapped.
The incredibly complicated driver must come out before the LED can. The LED is on a LED copper base and then its solder bonded onto a huge HS. There are like several layers with separate switches, adapter plug and a couple of driver layers hold together with like 6 washers, screws and retainer that must all be dissemble just to get to the LED.
Must reverse the process to get everything back in. Check for beam and if its not good everything must be redo again. The XPG2 dedome is a tiny LED in relatively huge reflector. A tiny shift ruins the lux, and focus.
The driver is a pain to mod too. The driver was designed to drive the much more current demanding SBT70 where there ar emore or less flexibilty with the drive. We don't have this flexibility as we are pushing the LED and heat-sinking to the very limit. Turning down the current is a must and is tricky. A bit to high pops the LED or tint shift and we loose efficiency. A bit too low and we might not hit out 1M lux goal or even 900K for that matter. A lux meter need to be used to check progress along the way. Numbers jump all over the place too. Another problem is all drivers are a little different. This is what happens when you have complicated electronics with too many parts. Too many components could builds up greater uncertainties/tolerances so every driver has to be treated independently from one another. Cant use the same exact mods for all the drivers.
To me this light mod is like a chemistry balance equation. Beam optical physics must integrate seamlessly and balance correctly with its electronics to reach our goal.
DriverVNX2 can be used and our problems would be greatly mitigated. However, I want the factory driver as it has great current regulation, works well with the dual stage switch design and retain the useless LCD that I kinda like. LOL
So...Yah changing the LED in your light + driver tweaks is like a brand new mod...Tough for me to do and to charge. Therefor for this light I will only mod a brand new one. Sorry.
