can you buy a heat sync for your ballast if it didn't come with one, I have made one but it still heats up to around 45c after 18 hours but without goes 65+c in 4hours without, i wondered if you could get one that cooled it to around 20-25c, have googled it but can only find ballasts that come with them already, or has anyone got any tips for cooling it.
cheers

well if your not scared of electronics, you can move your ballast internals to another ballast body "fairly" easily. Look for a broken ballast or something you can use. I assume you have a fan on the ballast already? Just having air move over the ballast should be good for a 10 degree lowering. Is your ballast outside the growroom? It should be. My friend cut holes in his ballasts and installed little computer fans so there is air running through them as well as over them. They sit at about 25-35 degrees C (1000 watts) depending on weather.Quote:
