The LED-8100-40K is a 20-watt LED retrofit designed to replace outdated low-pressure sodium SOX lamps, converting a traditional 35-watt SOX footprint into a modern, efficient LED solution. With a 4000K color temperature and a lumen output around 3,022 lumens, this unit provides a bright, white light suitable for outdoor and area lighting where dark-sky-friendly performance is desired. The design emphasizes targeted, directional light to minimize stray glare and maximize illumination where it’s needed, helping to maintain visual clarity in large outdoor spaces while potentially reducing energy use compared with legacy sodium sources.
Construction and features include an innovative aluminum heat sink and advanced active cooling, which work together to manage operating temperatures from -40°F to 122°F and maintain performance over a long service life. A USA-designed internal LED driver supports 120–277V operation, and the unit includes a support harness for straightforward mounting. A rated 50,000 hours of operation and 6 kV surge protection provide durability in demanding environments, while the fixture’s compact form factor (approximately 12.21 inches in length and 2.83 inches in diameter) makes it compatible with many existing SOX retrofit applications. The LED-8100-40K is designed to replace up to a 35W LPS SOX, delivering similar light distribution with the benefits of LED efficiency and longer life.
This product is intended for applications previously served by SOX lamps, particularly where retrofitting to LED can reduce energy consumption and maintenance without changing external mounting infrastructure. When planning upgrades, ensure your ballast and wiring configurations align with 120–277V operation and consider the environmental conditions listed (extreme temperatures) to confirm suitability for your installation. The package size is listed as “Each,” and the unit carries a Bayonet lamp/base type as part of its retrofit compatibility."
