This 4' LED strip light retrofit kit replaces the ballast and tubes of fluorescent strip fixtures. The 40-watt integrated LED light emits 5,200 lumens of natural white light—equivalent to the output of 2 32-watt fluorescent T8 tubes. It operates on 100-277 VAC and lasts 5 times longer than fluorescent fixtures. Installation brackets and a 0-10V dimmable constant-current driver are included. Brightness can be controlled with a 0-10V dimmer. This LED strip light retrofit kit is perfect for warehouses, supermarkets, workshops, basements, garages, and more!

natural light color, decent amount of light

I like the natural light color, decent amount of light and good uniform light distribution for ceiling mount applications.
Makes a slight humming noise from the transformer.
