Most growers care a lot about UV , that's why they either supplement UV with a T5 or use a lighting solution that has enough UV. The only reason you don't care about it is because you are new to growing and don't know what you are doing yet. Good luck .But speaking from a €€€ perspective (I pay 18c per kwh) lights I can attest (not sure till this grows over for comparative reasons and I wanna lollypop n shit. Who gives a fuck about UV anyways I want par n drop some photon bombs.
No reply about sending off the new lenses n reflectors shame
