            Comments about Bulbrite 6W 9 3, 4in T4 Cool White Fluorescent Tube:

            I ordered the wrong size bulbs. Bulbs.com sent my order quickly, and well packed. When I had to return (due to my error) the customer service agent was polite, and helpful. Will keep you in mind for future bulb orders (around the house), and for recommendations to friends.
            Thanks!

              Are all F6T4 fluorescent bulbs 9 3/4 inches long?

              • CUSTOMER CARE

                A:

                The length of an F6T4 fluorescent can vary depending on manufacturer. It is best to measure either an old bulb or the fixture to make sure the correct length is purchased.
