I know you dont have a SP, when this post was started, they did not exist. I was merely providing additional feedback, and experience as I had a very difficult time finding any actual grow results or photos in regards to any of the lights mentioned.
The TS have a nice coverage footprint as well and a bit better ease of use for a tent as you only have to adjust 1 fixture.
Personally I would avoid any cob lights as they dont tend to have a very consistent or even spread. They have very bright hotspots followed by sudden dropoffs. This is why QBs tend to perform better across the footprint... they offer a more consistent and even coverage.
@VILEPLUME nice work thus far, i am hoping to run my sf4000 against the 2 sp250s and see which is better. AS stated above I think 3 sp250s would murder, but thats cheating as its nearly 750watts. So for testing to be fair, 2 it is since the sf4000 is also 480watts.
