1. Light source: SMD led 3528. 2. Working voltage:DC12V. 3. Output power: 4.8W/M(60LEDs). 4. 3 units LEDs cuttable. 5. With 3M adhesive tape backside for easy to install. 6. Two designs: waterproof and non- waterproof, can be installed indoor and outdoor. Advantage: 1. High Luminous Efficiency. 2. Fast heat dissipation: Good PU resin cover for the led strip will not easy turn yellowish and broken in winter, Fast heat dissipation leads to long lifetime of 50,000 hours. 3. Great lighting source: The chip of led is of high quality, which is from Epistar in Taiwan. Or 1W led from Edison. 4. Quality of light: FusionBrite Lighting distributes light more smoothly throughout the entire case to improve average illuminance. 5. Low brightness declines: The white light is adopting new technology, less than 3% light decay in 3000 hours, about 10% to 15% in 20,000 hours and 25% in 30,000 hours.
