This SAE Recommended Practice provides general design performance requirements and related test procedures for LED “white” lighting unit assemblies, other than signal and marking devices, used on Earthmoving, Road Building, and Maintenance off-road work machines as defined in SAE J1116. This report is intended to serve as a guide to standard practice and is subject to change to reflect additional experience and technical advances. Many lighting devices are now using LED light sources for signaling and marking applications. These light sources now have performance equaling or greater than the incandescent and halogen light sources previously used. With this technology being employed, it is reasonable to address this usage in machine work lamps with recommended practice in the design of a LED light source device. Photometric Tables 2 and 3 have been taken from SAE J598 as being reasonable and applicable to the general trapezoid and flood patterns used for work illumination on this equipment. This document is cross-referenced with SAE J2121; therefore, both documents should be published at the same time.
