I use two 450's and they work great. Zero problems, and I grow some big buds. I guess your mileage may vary.
After hearing all of the Hopla over LEDs I decided to give them a try....
I took out my 600w HPS and put a Vipraspectra 600 and a 90w RED LED in my flower box... (350 actual watts)..
I gave it 3 good tries (6 months).... My best yield was 42 grams cut and dried...
I really gave it a solid try as I have been flowering in that box for ten years.
In order to be fair I used a 400 watt HPS in the exact configuration, soup to nuts.
It wasn't the best run but yielded 95.1 grams cut and dried. The buds were bigger and harder.
I'm sure someone is doing well with LEDs, but I will stick with the HPS.
