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