When using HID lighting you MUST control your lighting cycle with a contactor timer. This is because a normal domestic timer unit cannot withstand the high electrical conductive load required to ignite the HID lighting. Plugging HID lighting directly into a domestic timer unit will cause the timer to prematurely fail and lead to a potential electrical hazard which may result in your lights being fused either on or off. The Black Box Contactor range is a professional heavy-duty industrial lighting switch that offers unrivalled quality and reliability.
