Good day DGC. I recently purchased a light from a local used site. It is a Quantum board with two drivers at 240w each. I know everyone says use Samsung lm301h or lm301b diodes and meanwell drivers. This light does have Samsung diodes but the drivers are just a generic Chinese driver. Is it possible to tell what diodes these are or is there a big difference between the 301h and 301b? Lastly if I have driver failure is it fairly simple to swap out the driver? Thanks guys, Bringing myself into the new age of Technology and I made need a little help along the way.
