The new SynchroLight III is the ideal solution for preventing overheating in macro photography lamps. It synchronizes the signal from the stack controller (can be our MJKZZ IR-Controller, USB-controller, WiFi-Controller or any other system) with the light activation (OGGLAB DB120EB or UL100WB) and the camera's shutter release. This synchronized on-off sequence significantly reduces the temperature, allowing you to use your lighting at maximum power without risk. Optocouplers isolate the camera, protecting it from potential electrical damage or interference. The SynchroLight III can be connected between a focus stack controller (manual operation is also supported) and a dimmer switch, or directly to the LEDs. Important: The SynchroLight III operating sequence starts when it receives a signal from the stacking controller (or Test/Manual Trigger) It turns on the lights, waits 0.1 seconds, and then triggers the camera's focus and shutter. For further details, please refer to the datasheet and the connection instructions. Please watch this video from Synchro Light (version 1) to understand how it works:
