The Peterson Manufacturing 359 Series LED Cove Light features a 1" by 18" bar of Great White LEDs, which offer an output of 600 lumens per unit. The 359 Series light requires no cutting into trailer ceilings or side walls to install heat-dissipating mounting pans and conduit, thus reducing material costs and eliminating loss of R-value in insulated cargo areas. Simple no-splice harness connections avoid wiring problems while saving even more on labor costs. Designed for use in any environment from -55 degrees to higher temperatures, the 359 Series is ideal for a wide range of applications from heavy duty dry van and reefer trailers to smaller box trucks. An interior control module/timer switch is also available as an option.
