Through reflection and refraction, lighting optics place light where it’s wanted—and away from areas where it’s not. It shapes a wide distribution of light into a selection of beams, from narrow spotlights to wide floodlights. Ketra’s TruBeam optical system is our unique, patented approach to optics. A tightly packed cluster of LED die within our proprietary silicon dome creates a small-point light source. A reflector optic collimates the light, while a secondary pillow-lens optic smooths the beam. By combining the reflector and lens, Ketra produces the maximum range of beam spreads at a uniform color and intensity.
