i do not have experience with running a legal grow room, but from a misspent youth working in the service industry, i can tell you that in any kind of commercial setting, bulbs have to either be coated or behind some kind of shield. the florescents in coolers are in plastic tubes, light bulbs in walk in coolers have to be in shields of some kind, older ones are tempered glass jars, newer ones are plastic.
i'd check with the local inspectors, tell them what you want to do, and ask them whether its legal or not. they may require a fire suppression system to be installed, if they allow it at all.
