Pls. check Arcadia D3 + 12% uvb.....see what you think.The fs+UV has more red and other colors but less overall UVA/UVB. These really are designed to supplement white light led such as QBs and be Cobs. If you look at the spectrum above you will notice no spike past 545nm meaning we didn't use red phosphorus. Around 40% of the light is in UVA/UVB. These have a spike at 285nm which is right where you want it as far as UVB.
