So i think im to the point that i need to change bulbs in my 315w cmh fixtures, pretty expensive bulbs to be changing every year or so, my last run yeilds were way lower than expected, i also run 260 w leds from hlg as supplemental lighting to the 2 315's in a 4x4, so should i go all led or change bulbs in 315s? I was looking at a timber fixture or perhaps buying a few more 260 w hlgs
