The importance of reflectors on LED highbays.
Do you ever wear a baseball cap or sunglasses? Ever use your car visor? These shielding actions reduce glare, or “bad” light that detracts from our ability to see. In a factory, warehouse, or retail facility, highbays are installed to light the space, but if the highbays are unshielded, glare interferes with what we can see. In commercial settings, glare is more than an inconvenience. This low visibility can hurt safety, productivity, and health.
Below are three photometry tests on the same highbay. The first with no reflector, the second with a shallow reflector, and the third with a deeper reflector. The glare reduction, while having little impact on lumen output, is dramatic.
Using a reflector, not only are high angle candela reduced, but they are also emitted over a much larger surface area, reducing high angle luminance by a hundredfold! If your facility has light-colored ceilings, installing reflectors has the added benefit of producing uplight. Uplight further reduces apparent brightness, eliminates the “cave” effect, and makes the space feel larger.
LexaLite® brand glare shields, from the economical and shallow LENA 16™ to the deep, high-performance S16, kill the glare without killing the light. Specify the LENA 16 or S16 by LexaLite on your next highbay project. We can customize the mounting mechanism to fit virtually any highbay.

(Niles, IL) -A.L.P. Lighting Components, a leading global manufacturer of lighting components and kits, has added the Rayder™ post-top prismatic sphere to its 400 Series injection molded optics for outdoor lighting. The Rayder is designed to deliver a uniform distribution, higher efficiency, improved CRI, outstanding glare control, and a timeless appearance.
Today’s new post-top installations and retrofits need to be energy efficient, aesthetically pleasing, and provide safe illumination of walkways and streets. The Rayder excels in applications where brightness control is a priority. The Rayder’s optics reduce high angle glare and hide LED light sources while delivering a uniform glowing appearance. The Rayder also offers a significant improvement in efficiency when compared to diffuse or translucent blow molded spheres.
Suitable for 10′ – 20′ poles, the assembled spheres are 19.2″ in diameter, and are available with either 8″ diameter neck or other custom bottom openings. The Rayder is offered in Clear Optical Acrylic, Diffuse Acrylic, and Clear Polycarbonate. The top and bottom halves are easily attached using the affixed UV stable high bond double-sided adhesive ribbon for fast assembly and mounting. Acrylic versions are covered by a ten-year limited warranty.
“Optical glare control and the delivery of IES distributions are paramount features of A.L.P. LexaLite’s post top and dusk-to-dawn refractors,” says Kurt Puffpaff, National Sales Manager for Proprietary Products. “Utilizing A.L.P.’s existing optical prescriptions will increase efficiency, reduce glare and deliver light where light is needed,” he states. “Many fixtures incorporate white or diffuse lenses or no lenses at all. Applying A.L.P.’s optical component will improve fixture performance and application effectiveness,” Puffpaff concludes.
A.L.P. is a leading global supplier of lighting components, offering a diverse line of products and services for lighting OEMs and the aftermarket. From LED to legacy applications, A.L.P. offers the industry’s most comprehensive line of LED fixture kits, vapor-proof enclosures, unwired fixture bodies, louvers, and reflectors. A.L.P. Brands include Steel Craft, LexaLite®, and Reflek®
