4 foot T8 ballast bypass LED tube light for replacement of fluorescent tubes. This tube is single end powered and requires a non-shunted socket at the powered end. Direct wire LED tubes can replace T8 or T12 since without a fluorescent ballast in place tube diameter and wattage is no longer a factor. 5000k bright white is a crisp clean white light with little blues or yellow tones and may also be referred to as daylight in some cases. Only 14 watts of consumption saves over 50% in energy compared to comparable fluorescent tubes.
