This LED panel light perfectly fits into your ceiling and occupies a smaller space which is more concise and highly attractive. The panel light is able to do this because of the built-in driver, meaning you do not need extra accessories and gives it an ultra slim appearance. This makes it ideal for use in homes, hospitals, schools, offices, stores and any other place that requires high efficiency lighting. 【2*2FTSpecifications】 Wattage: 40W Voltage: 100-277V AC Equivalent: 300W incandescent light Luminous flux: 4000lm CRI>80 Lifespan: 50,000hrs Beam angle: 120° CCT: 5000K Daylight Dimmable: Yes Dimming range: 0%-100% Working temp: -4℉-122℉ Material: Aluminum 【1*4FTSpecifications】 Wattage: 30W/40W/46W Voltage: 120V Luminous flux: 3000LM/4000LM/4600LM CCT: 3500K/4000K/5000K UGR<22 Dimming Range: 5%-100% Dimmers: Compatible with triac dimmers (EATON：AAL06-C1) Lifespan: 50,000hrs Working Temperature: -4°F-113°F Housing Material: Aluminum Housing Color: White
