I just picked up 2 hortilux 315 cmh bulbs, they are bigger in size. I will give them a shot. More UV ?? I will leave 1 of the three lights a philips 3k and run this batch of clones.
I just switched from cheap led's to cmh, both 630w and 315w, I now use these for both veg, and flower. I couldn't be happier with these lights. Best money I have ever spent.
