I have a 400w hps running on an 600w hps ballast. enclosed reflector box with glass. can i run this with out air cooling it and for how long? please help
Thanks abunch dude. so should i take the glass out?Regardless of the higher wattage ballast you will still produce a large amount of heat from your bulb, I have run a 150w hps bulb from a 400w ballast without cooling but not enclosed under glass for many crops without too many problems, thats not to say it was ideal. If its possible i would recommend some sort of cooling
Good question, but soon i will purchase a hortilux 600w. i bought the system from a friend wit the bulb.does running a 400w bulb on 600w ballast only draw 400w of power from the ballast? or are you wasting 200w on heat. seems like you would be better off buying a 600w and a fan than using a 400w which will not last as long with extra power and may burst.
