                Comments about Bulbrite 13 Watt, 21 Inch T5 Warm White Fluorescent Bulb:

                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.

                  this light is used as under cabinet lighting in my kitchen. It provides a great light and also keeps my electrical draw down.

                          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
