Hey I thought I might chip in my two cents here since I often deploy these LED/CMH light combinations into lighting arrays that I design. For CMH, I love the RA Reflector from Sunlight Supply. Like the Cycloptics that @cschubert recommended (great choice, BTW), the RA has a vertically-hung bulb, and they are fairly inexpensive. I found one on Growers House in case you wanted to check it out. I often integrate them into my study formats as well because they run cooler than HPS but consistently produce deep-penetrating light; I thus get consistent results. Check out my Harvest Gold Study to see some of the results I got off one light in a 3x3. I almost always pull at least one pound per each 315 watt light.
I like to mix these lights with a variety of LED’s. I like the broad spectrum LED’s produce and the tunability of many fixtures. I have tested many brands. I like the combo of CMH/LED because I get light penetration, broad spectrum, and lower energy bills from light/HVAC power consumption. On another LED note, I have recently started The GrowFlux Bloom Study and will have results coming soon. Stay tuned!
I’m always available to chat about LED’s and CMH lights; just reach out!
