The on or off-camera Amaran AL-528C Bi-Color LED Flood Light from Aputure is an LED panel that uses 528 CRI 95+ LEDs to render colors with precision and accuracy. Color is variable from a warm 3,200K to daylight-balanced 5,500K,+ meaning that you can easily match other light sources, balance the unit with ambient light conditions or use the color range creatively, all without resorting to time-intensive filtering. The AL-528C produces a flood 75-degree beam angle with a brightness of 725 lux at a distance of 3.3', and features a stepless rear dimming dial for adjusting light output from 0 to 100% and a second dial that displays your selected color temperature. The AL-528C can be powered by the included multi-voltage AC adapter or optional Sony F/FM/QM type batteries using the dual rear battery slots. Four LED indicator lights on the back of the unit display the remaining battery life.
