You're not paranoid...just not realizing that the glass of the bulb filters damaging UV rays. Most manufactures take it a step further in their agriculture grow lights by applying an additional coating on the inside of the bulb.

Add a another piece of glass ala a cool tube or hood if its that much a of concern to you.
