1. Power LED inside. light efficiency will over 90lm/W2. We use 3*1W LED power LED to design. the brightness be same as 20W traditional U type lamp3. PMMA Materials ,special optical design and aspherisc surface design be used in LED lens ,can   be accomplish lighting reflect,To improve brightness 4. PWM high efficiency power supply is used. it has from 180V-265V wide working voltage,and it has constant current   320mA output. it can  guarantee LED will be OK if voltage is not stabilizate.5. We use 6500K LED to make this products. it is very suitability our eyes6. special heatbody . surface temperature is under 40degree Centigrade7. 6% light loss if you working continue 1000hours. the lifetime will be over 50000hours8. The good figure will show your worshipful and luxury status.
