An apparatus for retrofitting a HID lighting system includes using existing components of previously installed HID lighting systems such as its ballasts while replacing some capacitors to adjust the power supplied to a retrofit LED luminaire. Unused ballast drivers are removed, and a self-contained ballast driver assembly is mounted into the electronic control enclosure of the previously installed lighting system. Some of the retrofit LED luminaires include an uplighting lens, an optic, or a diffuser for providing uplight. An aiming bracket and an aiming plate allow for the horizontal aiming angle of a light luminaire to be set.

The present invention discloses a plug-in tube lamp, wherein power supply lines of multiple light source boards are integrated in a connecting board, all connection paths are concentrated within the connecting board. This avoids redundant and tangled wiring, resolving the disordered cabling inherent in conventional multi-light designs. Removing external wires reduces conductor wear and poor contact, lowering short-circuit risk. Standardized plug-in mating between pin and female headers forms a stable electrical interface, avoiding wire routing and soldering, and enabling rapid assemblyx2014;enhancing production efficiency and reducing labor costs. The connecting board provides rigid mechanical support to avoid connecting loosening caused by pulling or vibration ensuring long-term reliability. Moreover, the number of pin header groups is adjustable according to the quantity of light source boards to accommodate varying brightness requirements.
