What are QuarterLites


QL4 QuarterLites are low energy lights using four high brightness Light Emitting Diodes.

They fit on to the back of the sign box and light is emitted sideways through 360° diffusing off the sides and back of the box to produce an even illumination on the front face.

The LEDs are mounted on a flexible PCB with a circuit shunt and connector and are thermally bonded to the aluminum heat sink to keep the light cool.
