We understand that every customer has unique needs, which is why we offer flexible design options for individual functionality and lighting parts. For instance, we can customize our products with features such as a 480v twist lock photocell, low voltage controller, high-strength penetrating material controller cover, and aid-design for NEMA receptacles or Zhaga sockets for extended parts. This ensures a better fit for light fixture connector systems, such as the BS5972 standard twist lock photocell with a 7 pin receptacle that allows for easy cable wire connection to the controller kits. This breakthrough surpasses the regular version NEMA JL-240XA with wire gauge #16 and #14 leads.
