Crap I guess vipar only has a 2.5x2.5 led flower that doesnt have that lenz tech. Weak edges like the mars. Only would be getting it for reduced fire hazard. I guess no rush to upgrade those.
They do give the same ppfd at 3-4 less inches height so thats good but ya. I decided to buy the light when I should. Was just expressing Im starting to be more geeked than usual buying a light.
I guess starting to really like growing on another level.
