do ballest and lights have to have the same watt rating? i understand you cant install a 1000w light in a 400w ballest and expect it to work, but can you reverse that without any damage? say a 600w ballast and a 400w light.
also is it worth the extra money for a digital ballast rather then a normal mag switchable one?
