When I asked about that (here or in another thread?) distilling down the responses, the consensus was that without the lenses the lights are only marginally useful... but since its a scrog, maybe I'll try it. Lights come on at 10pm, I can take a look then. I even contacted Optic about this, and they strongly recommended keeping the lenses on, but referenced it for penetration reasons primarily.
But the bottom line, its not enough light for the space I'm expecting it to cover, my bad for not doing more research before purchasing. If you were to start a DIY thread and ask how many Vero 18's would be recommended (with or without lenses) for a 4x2, I would bet the answer would be minimally 6, with several people recommending 8 (and then of course the other end of the bell curve recommending 10+).
It probably looks like I'm trying to dis the Optics, but I'm only mad at myself. I'm a newbie, and I did not understand that no matter the light company, you can not rely on their recommended footprints. You need to ask impartial experts, and luckily this site has a lot of them, so future buyers can spec their spaces more realistically using this better information. Using two 120's within their recommended footprint -- "Coverage Area: 36″ x 24″ @ 16″ above canopy" -- the lights are not going to kill my plants... they are just going to give me a very imbalanced scrog, with decent growth in the middle and significantly less around the edges.
Jimmy has one light over one plant, maybe he could measure the plant's width for us, but I'd guess that its canopy is within about an 18"x18" area -- which seems to be a reachable footprint from a 12(?)"-16" height during flower. In my humble opinion, that is a footprint that this light can do justice at. I am asking each of my two to light a 24"x24" area, that in my opinion is outside of their optimal reach.
