LED tube lights are direct replacements for linear fluorescent lamps. They are designed specifically to retrofit existing fluorescent fixtures that can take the form of troffers, shop lights, wraparounds, linear strips, linear high bays, and vapor tight fixtures. Throughout the world, luminaires that incorporate linear fluorescent lamps had been ubiquitous in commercial facilities and industrial spaces which include shopping centers, retail buildings, office buildings, educational facilities, hospitals, logistics centers, warehouses, etc. High energy and maintenance costs are a particular burden to facilities with their lighting infrastructure based on legacy technologies. As energy codes are prescribing ever lower allowances for power consumption and the global call for carbon reduction grows ever louder, technology upgrading is seen as a prime mechanism to address challenges. Tubular LED (TLED) lights are products designed to facilitate a rapid and safe conversion from fluorescent to LED technology, allowing for immediate energy savings and performance improvements.
There is a fundamental tradeoff between the labor cost and ease of installation when it comes to the choice of a TLED retrofit solution. Furthermore, this choice may result in safety concerns and has a profound impact on the product efficiency and lifespan. These complications have to do with the ballast, which regulates AC mains power to achieve suitable voltage, current and waveform for starting and operating the lamp. In retrofitting fluorescent fixtures with LED tubes, it is important to weigh benefits against costs of different options. Depending on the configuration, LED tube lights can be classified into four types: Type A (Ballast Compatible), Type B (Ballast Bypass), Type C (External Driver), and Dual Mode (Type A + Type B).
