explain:Note: Panel battery and remote control are not included.Because of its lightweight and durable structure, you can take it with you.There are two separate buttons on the back of the panel, which can adjust the color temperature from 3200K to 520K, and adjust the brightness as required.The 2.4g wireless remote control can easily adjust the brightness, channel and color temperature to a maximum distance of 20m from the light.The white light filter can weaken the light source and improve the skin color of the portrait.The adjustable U-shaped mounting bracket directs the light to different angles for better shooting effect.The design of the flowmeter can better control the light and create an ideal lighting effect. Make sure that stray light from other areas of the subject does not reflect into the camera lens and cause reflection. It protects the lamp beads when the flux cutter is turned off.Specifications:LED beads: 660 pieces (330 white+330 yellow)Voltage: DC 12-15VPower: 40WColor temperature: 3200-5600KLumen: 3360lux/mCRI:96+Power supply: power adapter or Sony lithium-ion battery NP-F550 NP-F970 ″ Note: battery is not provided)Battery output: DC 14.8VInput voltage: 200-240VPanel size: 23.2x20x1.9cmChannels: 1-10 and "88"Transmission distance (about): 2.4g, 20mPackage content:1x 660 LED adjustable video panel with LCD display1x white diffuser1x power adapter1x power cord1x 2.4 g wireless remote control (without battery)1x transport bag
