Street lights have four main functions in the modularized design. OPTOTECH considers practicality as the highest priority. The internal structure is designed with a patented module that uses a hinge and E type ring buckle, making it easy to maintain and replace by a single person. The product’s unique cooling technology performs quickly and effectively through a heat sink that incorporates a heat pipe for thermal conduction process. Its new optical design meets international standards with a perfect butterfly-shaped photometric curve that was designed with safety in mind. The product’s photometric curve produces better illumination and achieves a more comfortable lighting effect than other similar systems. Its excellent power module with 90% and above conversion efficiency and its constant current output increases the LED lifespan. Other differentiating feature: Street lights that can be powered by solar or AC power.
