Retrofit tube lights are a type of LED lighting that can be used to replace traditional fluorescent tube lights. They are designed to be compatible with the existing fixtures, without the need for a complete fixture replacement. Retrofit tube lights are energy-efficient and can provide a brighter, more natural light than fluorescent tubes.

Typically come in two forms: ballast-compatible and ballast-bypass. Ballast-compatible tube lights are designed to work with the existing ballast, while ballast-bypass tube lights require the ballast to be removed and rewiring of the fixture to direct power to the LED tubes.

Are often preferred over traditional fluorescent tubes because they are more energy-efficient, have a longer lifespan, and are environmentally friendly. They also offer a better quality of light, with a high colour rendering index (CRI), which means that colours appear more vibrant and true to life.
