T5 LED lights are intended to replace traditional T5 fluorescent light tubes and are installed in the same manner as existing tubes. There is generally no need to modify the existing socket or light enclosure to install a T5 LED tube.
LED lights such as T5 replacement tubes consume less power than traditional fluorescent lighting and do not contain mercury, so they are safer to handle and better for the environment. LED lights are also free of the buzzing noise that plagues some fluorescent lighting. LED-based T5 replacements are also sometimes more expensive than traditional fluorescent tubes, but long-term savings from energy efficiency gains and the long lifetime of LED lighting can offset the initial cost over time.
