Patented GRAVITY® LED Technology

Leveraging decades of optical and lighting design experience, we created a proprietary and patented LED reflection system for our Gravity LED lights and light bars. Fusing traditional reflector design with cutting edge LED technology resulted in the most power efficient and optimized light output on the market.

Gravity® Reflective Diode (GRD)

A KC patented LED positioning and optical system, KC's GRD CORE holds the LEDs and channels every lumen into an optical reflector for maximum light efficacy. Maximizing lumens and minimizing loss, we redirect the light using our precision-designed reflectors to achieve high output, distance and beam control all while keeping the wattage low. Having designed and produced performance-engineered reflector optics for over 50 years, KC developed the GRD system to capitalize on the full lumen potential of each LED to maximize light output and achieve precise beam patterns.

Gravity® Projector Optic (GPO)

KC's GPO is an optical technology that combines an optical projector lens with our patented GRD technology to create maximum light output while being compliant with certain specifications and standards. GRD technology aims LEDs at the most effective angle into our optical reflectors and projects them forward. GPO further intensifies the beam and also allows for sharp beam angles and cut-offs that meet DOT, SAE and ECE compliance specifications.
