    Comments about Bulbrite 13W 21in T5 Warm White Fluorescent Tube:

    This is a low cost little bulb, but historically has always given me long life. In this cost range the main thing that I am concerned with is not having to reorder/replace bulbs frequently. This product has fit this requirement perfectly.

            I bought these along with some 8W 12-inch bulbs for under cabinet light fixtures that came with cool white bulbs, & looked out of place compared with the warm white lighting in the kitchen. These make the overall lighting in the kitchen look "balanced", & have performed just fine so far (about a month). I highly recommend them.

                      Satisfactory brightness and color. BUT, original GE lamps lasted approximately six years, and 4 out of 6 of these have failed in less than six months (same fixtures and operating conditions).

                      Not a good buy at all
