Can I Use A 400w Bulb In A 250w Ballast

The ballast is trying to push that 400w into the 250w lamp.

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

This shortens the life. I was considering changing the bulb as it has done 2 grows so should i buy a 250w or 400w bulb. From all that i have read about mh s you can t run 250 watt bulbs on a 400 watt ballast. The ballast is trying to push that 400w into the 250w lamp.

The ballast is able to provide 400w. I don t think it would work the light is only capable of using 250w. The 250w lamp will burn hotter and a little brighter than normal but will use almost as much power as a 400w lamp. Lamp 400 ballast 400 etc.

The 400 will light but not any brighter than a 250 would. If you look at a 400 and 250 ballast side by side the 400 is bigger. If someone has experimented with a light meter and temps proving this is safe i would like to hear the results. 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.

This shortens the. You will eventually burn out the ballast or worse burn down your house. I would think that the ballast is rated for a max 400w. Use the proper setup.

The 250w lamp will burn hotter and a little brighter than normal but will use almost as much power as a 400w lamp. Same applies with the ordinary lamps in your house. Don t put a stronger light on it though.
