5W LED Ceiling Light General Information:Model Number CG-CL-3N5W(3lamps) Base Types 2wires Input Voltage AC 85 265V Work Frequency 50Hz/ 60Hz Dimensions 210mm*70mm Construction glass & Alluminium Rated Wattage 5.0 W Power Consumption 4.25 W Rated luminous flux 360lm Light efficacy ≥80lm/w Beam angle 30/60/90Degree. Rated lamp life time ≥30,000 Hours (MTBF) Lamp power factor ≥0.6 Color Rendering Index ≥75 Color Temperature 2700K---8000K Starting time 0.20ms(instant full light) Lumen maintenance factor at the end of the nominal life about 75%(±5%) Number of switching cycles before premature lamp failure ≥1,000,000 Times (5,000 Times in Lab). Efficiency >=85% (230VAC, 50Hz, FULL LOADED)Working Condition Temperature:-20 to +50 Humidity5% to 90%, Non-Condensing Followed Standard Safety:EN60598 (Pass 3750Vac High Pot Test) EMC:EN55015 Circuit Protection 1.Overcurrent Protection 2.Overpower Protection 3.Short Circuit Protection 4. Overheat Protection Application: Apply to hotel, various of selling places, shopping mall etc. Apply to office , conference room, exhibition hall,etc. Apply to living room, dinning room, kitchen, bedroom etc. Apply to airport, station, exhibition hall, library, hospital, school, factory and other public places. Special Advantages: Light source using COB(Chip On Board) direct encapsulation technology,this access to large-scale heat dissipation of module area. Facilitate the heat diverge from the white LED module to the LED lamp, This could suppress the temperature rises of the blue LED chips inside the module when the light source working., so it will remain luminous efficiency on higher state.Now the light efficacy can get up to 130LM/W Compared with other encapsulation technologyes, COB technology has the following advantages: low price; save space;mature process. Important Technology Information: 1.Pure aluminum plus 30% heat dissipation compared to normal general housing of Aluminum Alloy Casting Die 2.Streamline housing design, double heat spread area 3.Appearance with anodized treatment, increase by 20% heat radiation, by contrast. 4. Circuit design 1) Safety standard A. Optocoupler isolation circuit design B. Isolation coil transformers, non-inductive C. According to CE safety standards EN61547 + EN60598, and UL safety standards UL1993,UL8750. D If the products is abnormal, it will not damage the human and property, protect user safe effectively. 2) EMC Standard A. According to European EMC standard EN55015, and the United States FCC standard Part 18 B. Effectively resist surrounding electromagnetic environment effects, and inhibit the proliferation of electromagnetic energy to the surrounding environment.Remark: We are a led lighting manufacturer in China,our main products include: led lights, led lampen, led bulbs, led spotlight, led downlight, led ceiling light led panel light,led fixtures,led tube,led led tunnel light, led street lamp,led emergency light, led flashlight, led rechargeable light, indicator light, led torch light,led battery light,etc.
