I'm doing this for research purpose.

If one is to have a ballast that is rated for 430watt hps, do you HAVE to use 430watt light? or can you down grade slightly to a 400watt light on that ballast?

thank you

yep you can even use a 360 watt ive used a 400 watt bulb on a 1000 watt metal halide ballast, it fucking worked but i didnt run it for too long as i feared a fire but was kool though ran for 2 weeks before i switched it.

hmm i was wondering this my self.... We know it works but can anyone confirm it's safe to run 400watt on 430watt ballast?

Slightly different question, but would a 430w bulb be safe on a 400w ballast?

yes and its confirmed u can get an agro 430w for a 400watt ballast

BUT

430 watt ballasts are cheaper and because a 430w bulb can go in a 400w ballast we want to know if a 400w bulb can go in a 430w ballast?
