Why digital lighting? The Sun is high frequency. In order to make artificial light behave more like natural Sunlight it needs to be high frequency. Digital lighting makes for a higher quality of light 
that’s good for all living things...  

This is only possible if you have the proper lamp and ballast combination. 

STK Lamps contain UVA-UVB and the upper portion of UVC.
Exercise caution when working around any HID lamp that contains UV, always wear protective lenses.
