Alright Hudson, you've pretty much eased all my nerves regarding heating and lights, thanks. But, I have one more question..... Do you know how hot mini-ballast systems (ballast included in the lighting hood) get in relation to a remote ballast? I know it will be hotter with a mini-ballast system but they're so much cheaper than getting a seperate ballast, reflector, bulb, etc... Thoughts? Hopefully answers? Thanks alot, all of your information has been helpful.
