HO bulbs & VHO bulbs are fluorescents with "High Output" or "Very High Output" - meaning much more intense than NO (normal output) bulbs. HO bulbs & VHO bulbs are sufficient for most aquariums up to 20" deep, and most freshwater planted tanks (recommended tank size/depth varies by brand and number of bulbs). If you already have a ballast (it may be built into your hood or fluorescent fixture) rated for NO bulbs, it may not support your VHO bulbs, so check first.
