Operating Instructions
Your Sunco LED Flat Panel Light offers adjustable settings for both color temperature and brightness to suit various environments and preferences.
Selectable Color Temperature (CCT):
The fixture features a slider switch on the back to select between three color temperatures: 4000K (Cool White), 5000K (Daylight), and 6000K (Daylight Deluxe). Adjust this switch before final installation or by carefully accessing the back of the panel if already installed.
