Do you need to meet the new DLC® Premium requirements?

Are you struggling to meet the Standard requirements? LexaLite® Reflexor® reflectors can help you achieve the glare control numbers you need!

Design Lights Consortium (DLC) evaluates light fixtures against increasingly stringent standards of performance. Most recently, DLC published v5.1, which not only addresses fixture efficacy, color issues, and zonal distribution but also puts a value on glare reduction. The metric used is the Unified Glare Rating (UGR). If you are trying to qualify for DLC Premium, DLC requires that you meet the glare criteria.

In A.L.P.’s testing, we compared a bare “UFO” highbay with the same fixture adding both our LENA 16™ and S16 reflectors. Using the prescribed criteria, this test yielded the following results: bare UFO =23.9, with LENA 16 = 13.1 and with S16 = 10.9, respectively. Highbays need to be less than 22 to qualify for DLC Premium.

What if you are just struggling to meet DLC Standard LPW for your highbay? DLC now provides a 10% allowance if your fixture meets the criteria for UGR. Adding a prismatic reflector reduces LPW by 3-7%, and you gain 10% with the allowance!

Even the extremely shallow and economical Lena 16 has a significant impact on UGR. Why? It’s just math. Glare is based on several factors, including high angle light, size of the source, and background luminance. Our Reflexors improve all of these factors.

  1. Reflexors reduce high angle light, providing a shielding angle relative to their depth.
  2. Bare UFOs are essentially flat luminous surfaces. Reflexors increase the luminous volume dramatically
  3. Reflexors provide uplight, which increases the background luminance.

These three factors improve visual comfort and make adding a LexaLite Reflexor an easy choice! Make a better highbay while meeting DLC requirements for Glare by using LexaLite Brand Reflexors.

Press Release: A.L.P. Introduces LENA 16™, a Cost-Effective, High Performing, Low Profile Reflector

(Niles, IL) -A.L.P. Lighting Components, a leading global manufacturer of lighting components and kits, has added the LENA 16™ shallow prismatic reflector to the “S Series” of optics.  Designed for low-, mid- and high-bay LED fixtures, it offers superior glare control and an elegant aesthetic, combined with the versatility to accommodate a variety of light sources without expensive modifications.

The LENA 16 has a shallow design, optimizing cost without sacrificing high angle brightness control.  The 10.36” flat top allows it to be easily adapted and directly attached to many fixtures. The lower flange works with a wide range of bottom lenses and standard clamp bands.  The top can be cut to order with an opening of up to 10.66 inches.

Like their HID predecessors, today’s LED low-, mid- and high-bay fixtures should always be installed with optical or refractive control.  Without this control, they emit high angle glare, causing a reduction in contrast and negatively affecting color and focus.  By reducing high angle glare, LENA 16 improves visual comfort, provides even illumination, and can also increase worker efficiency in some settings.  It is suitable for warehouse, industrial, commercial, and retail applications.

LENA 16 is available in Clear Acrylic, Clear Polycarbonate, Interface Acrylic, and Lumieo® Acrylic.  It works with a wide range of LexaLite® brand bottom lenses.

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®
