The ts-600 is a little over 31 cm wide. So they will likely touch the sides of that little side part. But as far a s the lights go the work great for me in veg. I used a dedicated light and went thru to harvest with em.
I'm not sure how well they performed for flower, my yields weren't the greatest...but I stressed the hell out of her... and she an auto...but they did fine for veg. Ran pretty cool as well. I dropped like $80 on mine and am probly gonna buy a few more if they are on sale. Where are you finding them for $68?
