Dimmable LED (PF=power factor): PF>0.9 3100 W, PF>0.5 350 W Dimensions (mm): 81*33.4*34.8. Black. Easy to use: The LED controller allows you to adjust the brightness of the light by turning the knob and ensures that the room is bright. Turn the control knob clockwise: the light increases until it reaches maximum brightness. Turn the control knob counterclockwise: the light dims. Safety Protection: The LED dimmer has an electronic overheat protection function. It automatically turns off when the temperature reaches 80C and turns back on when it drops below 80C. Note: It is important to note that the required LEDs must be dimmable to avoid flickering problems with dimmers. The LED lamp must not be less than 3W. LED lamps must be dimmable and compatible with phase dimmers. When the dimmer is at minimum/maximum brightness but does not match the actual brightness and fine adjustment via the screws has no effect, the luminaire may have manufactured the dimming range.
