If the light is far enough away it would be ok, but it seems like a waste of electricity. I use 600W for flowering, but prefer my T5 (8 blub 200 or 400 watt) for veg and CFL for seedlings. Just my 2c.completed 7 grows
what I have learned so far:
environment maters more than nutrients
at least a dab of nutrients in every watering
effective flushing before harvest is critical to quality

Some light ballasts come with the ability to reduce the light to 75% and 50% to lower the intensity. My iGrow does this. Have a look at yours. If it doesn't, the next time you buy one look for that feature. It really helps if you're limited on funds to have multiple lights. It also saves from have to switch out lights if you only have one tent to grow with.Fast Buds GSC & Green Crack Auto's

My veg 600w is dimable as well. At the lowest (300w) setting the plants almost have to touch the bulb to get burnt.
The switch gets used often- to slow down or speed up growth,
Small seedlings stay down on the floor in the early days- get raised up later, or just left to grow up. There's a constant juggling act going on to speed up and slow down different plants at different times.

Thanks Weasel....Green I have some pics that I put up yesterday.....tent is 4x8x7....I have 2- 600watt vivosun in the tent. They have a dimmable ballast...After reading some of GWE...it is possible to have to high of lux......or to much light....it was not a temp issue. I had the 600watt MH bulds in and had them about 24" away.....I was able to keep my hand there without any problem for minutes....I now have them set at 250watt.....I am going to address the RH......

I guess what I was trying to offer is that a 4K MH bulb seems pretty close (in light spectrum) to a 2K HPS bulb, theoretically. Just wondering if anyone has used a 4K MH for flowering; the manufacturer states the 4K MH bulb can be used start to finish.Agromax XL tent, Sun System lo-pro Mag XXXL, SolisTek Matrix ballast, SolisTek MH/HPS bulbs, GH Flora Trio, CO2 bag, 3 gal Air-Pots.
