The control panel on the back of the lamp provides all relevant information, such as brightness, channel along with the group, and lamp temperature. In addition, the Godox LED500C has been equipped with a practical knob for brightness adjustment from 10% to 100%. This panel emits very high-quality light, without a flickering effect, and allows you to adjust the color temperature in the range from 3300K to 5600K. The Godox LED500C can be controlled remotely via the RC-A5 remote control (available separately), thanks to the built-in receiver. These devices can also be grouped and divided into different channels just as easily. Different parameters can be set for each device, for a group of devices, or for all of them (including switching off). This panel can be powered by a mains power adapter (included) or optionally by rechargeable batteries for Sony NP-F970 7.4V cameras (not included).
