Hey guys, I stumbled across these light covers that fit over CFL bulbs to change the color of the light. I was looking for a cost effective way to change the light on my regular grow CFLs to red without having to buy weak or expensive bulbs. I was wondering if anybody has used these, or if you guys think they might reduce the amount of lumen output to much? https://www.amazon.com/gp/aw/d/B014...id=1457936869&sr=8-5&keywords=moodies
