LS 600d Pro Firmware Upgrade Notice

In order to provide users with the flexibility to adjust the noise floor of the filmmaking environment
when needed, this firmware update for the LS 600d Pro features four new fan control modes. Users
can now designate the appropriate fan curve for their shooting needs.

What’s new in this update?
2021-Jan-06
1. Smart Mode: The fan will automatically adjust its speed according to the internal and ambient
temperature, so as to meet the needs of different environments in a more intelligent way. If the
ambient or internal temperature is high, the fan will spin faster, and as the light fixture cools,
it will modulate the fan speed accordingly. If the temperature does not reach the cooling threshold
of the fixture, the fan will turn off or remain off.

2. High Speed Mode: The fan can ensure continuous and stable output even in higher temperature
environments. We recommend activating this mode if the ambient temperature is 40°C or higher.*

3. Medium Speed Mode: This is the best mode for quiet operation in most environments and at room
temperature. In this mode, the fan spins at a slower RPM in order to achieve a quieter noise
floor. We recommend activating this mode if the ambient temperature is below 35°C.**

4. Silent Mode: This mode will force the fan to stop spinning, providing users with a completely
noiseless environment, while maintaining a limited output. In this mode, the maximum output power
of the lamp head is 60W.

*In High Speed Mode, the sound level of the fan is 31dba at a distance of 1 meter.
**Using Medium Speed Mode, the sound level of the fan is 27dba at a distance of 1 meter.

Note: 
*After upgrading to the latest firmware, the firmware version should be displayed as:
Control Box v1.5, Lamp Head v1.4;

*This update is only supported via USB. Sidus Link OTA updates will be available in the future.
