Hey mate it sounds good. How many lumens are hoping to get?
Do you already have the host can it handle the heat?
You could get the same performance out of a triple XHP-70 setup.
Are you going to run the LEDs in series or parallel?
Yea it’s a boost driver so you will have to make up 16 volts difference if used in series configuration . If you can make at least 2500 lumens each led it would be worth it. If you kept these LEDs are they xml2? You could get 7500 lumen from the light running direct drive.
Stock at 3amp each they will be able to do 5250 lumens but driven harder they can do much more. So if you want to build the xhp50 aim for high figures.
