Deep - Nice to see another screw in LED fan. Great grow so far. The corn cob lights would work well for ultra low wattage small vertical setups, but I like the standard lights with the globes removed so you can direct the light where you want it.
I'm going to make enemies with every LED lighting manufacturer in the biz when I say this but - I honestly can't see any reason to purchase pro LEDs anymore - unless the color pink really turns your crank.
OldToker - 14w/16w screw in LEDs are 5 bucks each at any home store, so your cost per watt is roughly 0.30-0.35 cents. My 250w/16 light panel covers a 3x3.5 to the point I have to back the lights off cause the plants are bleaching. You could build two of these for $150 and call it a day. I know other users are seeing similar results, Blynx routinely pulls .8-.9gpw and ScrogFrog just pulled 1.13gpw on his third run with screw in LEDs:
Yes, I know pink lights offer the "correct" spectrum for plants, but how much more do you actually get? I would assume terpene and trich density improve a little with the pro lights - but at 3-4x the cost, is it worth it? Now granted, the panels have better penetration than the screw in bulbs, so if you're dead set on not topping extreme sativas and you hate side lighting plants, go get a 600/1000w LED panel. Someone is going to have to run a side by side (screw in led vs pro led) one of these days...

Welp boys we finally did it. We finally broke the 1gpw barrier. I can't believe it TBH.
My last run was 107.6G dry with 4 plants in 2gal grow bags under 94.5w of screw-in LED's.
This is only my 3rd run with them, and it's enough to say they destroy any 150w HPS or any combination of CFL's.
Didn't take any pics due to my chaotic traveling lifestyle, but I can assure you this was the best yield I have ever had, CFL, HPS, anything in the past 8+ years.
Also have my 51w tent drying and it looks to be around 2oz as well.
Very impressed.
