FB40T12 Fluorescent Light Bulbs

FB40T12 fluorescent light bulbs are the u-shaped lamps that have been used for many, many years in a variety of applications including 2 x 2 fixtures and places where a tight area needs to be lit. There is a 6 inch spacing on center between the legs of this lamp and it fits into the same sockets that a normal T12 lamp fits into. There are a couple of color choices including cool white and warm light and even daylight although daylight is not considered a true full spectrum lamp like many of the color corrected ones are. These are not interchangeable with T8 u-bend lamps. The T8 operate on an electronic ballast and the FB40T12 fluorescent light bulbs typically run off of a magnetic ballast.
