The 4’ LED strip light fixture is a long-lasting and low-maintenance solution for retrofitting existing fluorescent fixtures. Easily install into existing fluorescent strip fixtures with the included brackets, replacing two 32-watt T8 tubes. Hinged brackets allow the fixture to hang during wiring to simplify installation. Construction is both durable and lightweight, with a white steel body rated for use in damp locations. The curved lens diffuses light, producing a uniform 120° beam angle. Ideal for retrofit applications, such as basements, workshops, and garages.

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.
