I did not buy my LEDs or drivers from them, but I bought their 12" heatsink kit and it is excellent. Very well put together and very complete with every screw, nut, bolt, washer, etc. From the special fan shroud to the plastic endcaps to the cool hanging kit, all of it is well designed and makes for a very clean looking fixture. I highly recommend the Makersled kit. Buying from LEDsupply.com was a pleasure as well. Quick shipping and good communications.
Good luck with the build. Post pics for all of us to see your handy work.
