i have been told by a local shop that is is safe to use a 600w ballast to run 400w hps ?
is this correct? obviously im no sparky but it sounds a bit dodgy

I was gonna say that, lol, but i wasnt sure on the name. I just knew they made ballasts like that.those are cal;led switchable ballast. i have a quantum that does a 250...400 and a 600 with a flick of a swicth......................http://www.quantumhort.com/images/content/ads/greyback_v1.jpg
thanks for my lessonLesson for you Moash ! The lamp determines the load . a 600 watt ballast with a 400 watt lamp doest mean 600w is being run to it .The ballast only draws what you load it with based off the wattage of the bulb.
By the way a 400 w ballast will not light a 600w bulb
Medi1 yes you can do that but thats not how it has to be the lamp has to have a lower wattage and it doent work with allof them anyways because of different sized capaciters on differnt wattage ballasts
thanks for my lesson
i suppose ill just call it human error when my 400w bulb burnt out on a 1000w ballast
also for someone that is so electricly inclined,why dont u know if it will work for a hps
thats is what the o.p. has
