Description: LOWCLED 4F series LED street light has low power consumption, high luminous efficiency and long service life. Honeycomb heat dissipation design. Wrapped structure design of module lens and radiator, which can enhance structural strength and prevent light leakage. Avoid light pollution caused by stray light. The whole lamp is anti-glare. The hatchback design of the power supply case is convenient of backward power supply replacement and maintenance. Embedded with level gauge, which is convenient for construction and installation. No stroboscopic, no delay in starting and eliminating the drawbacks of traditional street lamps. Rocker arm is adjustable from 0º to 180º . Photosensitive mounting position. Perfect combination of wind energy. Fully realized high cost-effective LED advantages of energy-saving and environmental protection. Professional outdoor surface treatment of lamps. Adding metal powder, improving heat dissipation effect, grinding texture, meeting 48 hours salt spray test and 28 days continuous exposure of solar radiation lamp test. 50,000 hours lifetime Specification: | Model | LL-SL4F-300W |
