1. Introduction
Reptile LED light module, usually enclosed in square transparent resin, resembling a square box in appearance, with four pins.It can pass through a larger current, and its design structure is favorable for luminosity, hence the Sardine LED has a higher luminous intensity compared to ordinary LED lights.The pin spacing design between the pin and the luminous part allows the eCOB LED to have better heat dissipation than general LED, and can withstand greater power.
