Lighting

Can you put 600 watt MH lights in a 400 watt lighting system

i have ran a 600 watt bulb in a 1000 watt ballast and it was fine.

mind you i didnt buy this equipment it was given to me.

i would definetly not recomment using a bulb with more watts than the ballast is built to handle.

you could start a fire or wreck your bulb and ballast.

No, No and uhhh, No.

You can put a lower watt bulb in a higher watt ballast, but it does not work with a higher bulb than ballast.
granted puting lower watt bulb in higher ballast normally shortens life of the bulb.
