Crazy Sale 12W LED Downlight

Product introduction :

LED Down Light can energy-saving 30% more than traditional downlight in the same brightness, its service life is up to more than 50,000 hours, which is 10 times more than them

LED Down lights Features:

Green Illumination: There is no harmful heavy metals such as mercury, lead and so on, no flicker, fast start in working, It can replace the traditional 1*18W or 2*11W energy saving lamp downlights.

Safe, efficient: Adopt internally installed wide voltage and wide frequency constant current topology isolation circuit design for power supply, small size, power conversion efficiency is greater than 88%.

Excellent heat: Ultrathin gear-shaped exterior design, aluminum die casting forming shell surface of the electrostatic spraying, This design of effective use of the lamp body contours and surface Process, effectively increasing the cooling area to improve the thermal conductivity of the shell surface of the LED surface temperature lower, more stable performance and longer life.

Circuit Design: Constant current isolated circuit design with wide voltage range and wide frequency. It is not only safe, but also small measurement with high efficiency and high power factor.

Long lifespan: Josun introduce the advanced thermal management technology of LED from Japan. The light decay of Josun products is very low and the lifespan is above 50,000 hours.
