Attaching a weaker light shouldn t hurt anything.
Can i use a 400w bulb in a 250w ballast.
The ballast is trying to push that 400w into the 250w lamp.

The 400 will light but not any brighter than a 250 would.
This shortens the.
Lamp 400 ballast 400 etc.
You will eventually burn out the ballast or worse burn down your house.
I was considering changing the bulb as it has done 2 grows so should i buy a 250w or 400w bulb.
If someone has experimented with a light meter and temps proving this is safe i would like to hear the results.
If you look at a 400 and 250 ballast side by side the 400 is bigger.
The ballast is able to provide 400w.
Two grows seems a little soon to replace the bulb.
The 250w lamp will burn hotter and a little brighter than normal but will use almost as much power as a 400w lamp.
Don t put a stronger light on it though.
I would think that the ballast is rated for a max 400w.
The 250w lamp will burn hotter and a little brighter than normal but will use almost as much power as a 400w lamp.
Lamp 250 ballast 250.
This shortens the life.
From all that i have read about mh s you can t run 250 watt bulbs on a 400 watt ballast.
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.
