Can i use a 400w bulb in a 250w ballast.

Lamp 400 ballast 400 etc. Attaching a weaker light shouldn t hurt anything. The 400 will light but not any brighter than a 250 would. The 250w lamp will burn hotter and a little brighter than normal but will use almost as much power as a 400w lamp.

I don t think it would work the light is only capable of using 250w. This shortens the. Don t put a stronger light on it though. The ballast is able to provide 400w.

If someone has experimented with a light meter and temps proving this is safe i would like to hear the results. The 250w lamp will burn hotter and a little brighter than normal but will use almost as much power as a 400w lamp. On the other hand in breakdown service if a lamp roasts and during a few days before the new purchase one can without risk use 1 ballast 400 per 1 lamp 600 the ballast does not put has the lamp badly to in no case. You will eventually burn out the ballast or worse burn down your house.

The ballast is trying to push that 400w into the 250w lamp. Use the proper setup. If you look at a 400 and 250 ballast side by side the 400 is bigger. I would think that the ballast is rated for a max 400w.

From all that i have read about mh s you can t run 250 watt bulbs on a 400 watt ballast. Two grows seems a little soon to replace the bulb. Same applies with the ordinary lamps in your house.
