To change the fact that the life span of present outdoor type LED power supply is shorter than 10,000 hours, our institute has designed the brand-new semi-permanent life-time product. Containing no electrolytic capacitor and adopting current type system control, our product offers full guarantee to the life and reliability of outdoor type LED power supply. The designed life-time is more than 50,000 hours and the operational temperature ranges meet the requirements of American military standards. Quality assurance is 5 years.
An 8,000-set experiment proves that the spread of the product’s characteristic technical specification is within 3%, no design problems were found.
