... and this was my reply:

"Typical "cool white" and "warm white" bulbs have very low output in the UV range. Daylight bulbs have more, but are not commonly used except for aquarium lighting and some commercial applications. To get signigicant UV from a fluorescent light (such as for lighting saltwater reef aquariums) requires specialized bulbs designed for that purpose (actinic bulbs)."

Bottom line. Don't worry about it.
