Diamond DS XML 150 Mods

I was given a DS XML 150 with the 10 watt cobs not working. Since all 4 cobs aren't working I have a suspicion that the driver is fried.

So what I'm looking for Suggestions on a chip and driver upgrade for the 4 cobs on the board. Maybe a revamp on the 3 watt diodes and drivers also.

Driver is definitely fried. Cheap Chinese Well-Lit driver.
So any suggestions on a driver to run 4 Cree XML's , or XML2's , maybe XP-E's.

Bump, Would this HLG 40h-12B work for 4 XML2 diodes ?
