Setting the fan mode
For operating environments where low-noise is a requirement or where the fixture will be operating in high temperatures, it is
possible to adjust the default fan speed to low or high using the “Settings
→ Fan mode” menu.
Setting the LED refresh rate (Frequency)
When using LED lighting with cameras, flickering can occur due to incompatible frequency settings which means the LEDs
and the cameras is not synchronised.
In order to avoid flickering and horizontal banding (rolling shutter) the i-5 series offers the ability to adjust the refresh rate (fre-
quency) in order to achieve flicker-free performance.
In the i-5 menu, go to “Settings → Refresh rate”, here you are able to set the refresh rate (frequency) of the LEDs to be:
• Dimmer optimized (low frequency), flicker can occur on cameras / highest dimming resolution.
• High frequency optimized (low dimming resolution), flicker is unlikely to occur / low dimming resolution.
• Custom value, from 0,2 kHz to 72,0 kHz. Adjust to a custom frequency.
It is recommended to have the i-5 configured to run “Dimmer optimized” whenever possible to maintain the best possible dim-
ming performance.
Does flicker or horizontal banding occur, it is likely because the i-5 is set to “Dimmer optimized” or a low custom value.
To avoid these phenomenons set the refresh rate to “High frequency optimized” or adjust the refresh rate to a custom value
above 0,544929 kHz (value of “Dimmer optimized”).
When adjusting a custom value, you want to choose a frequency high enough to avoid flickering and/or horizontal banding,
but low enough to maintain a good dimming performance.
Since there are differences between camera models, exposure settings etc., the optimal refresh rate settings will differ.
In order to achieve the best result, adjust the refresh rate through a preview monitor with a feed from the cameras.
