Light Efficient Design LED-8101-22K LED SOX55 Retrofit Lamp - 35W - 2200K - 3,232 Lumens - 120-277V

Light Efficient Design LED-8101-22K is a retrofit LED lamp designed to replace traditional low-pressure sodium SOX lighting. With a 35-watt input, it delivers about 3,232 lumens and a color temperature of 2200K, producing a warm, amber-toned light intended to emulate the performance characteristics of SOX lighting while benefiting from modern LED efficiency. The unit is built to operate on 120–277V AC and includes an internal LED driver designed to be US-designed and specified, along with an innovative aluminum heat sink and advanced active cooling to help maintain performance over long operation. A robust 6kV surge protection level supports reliability in harsher electrical environments, and the fixture includes a support harness for installation. The lamp is rated for up to 50,000 hours of operation, which can translate to reduced maintenance cycles in appropriate applications. The design states compatibility with squarely replacing up to a 55W LPS SOX, focusing on delivering directional light output suitable for outdoor or area lighting where dark sky performance is a consideration.

When evaluating this LED SOX retrofit, consider that the wattage is lower than the replaced SOX lamp while maintaining similar lumens, which can influence lighting layout and ballast or driver compatibility in your existing installations. The 2200K color temperature is on the warmer end of the spectrum, which can affect color rendering and ambiance in outdoor or signage lighting contexts. The product’s dimensions—approximately 16.70 inches in length and 2.83 inches in diameter—inform enclosure fit and mounting clearances, and the Bayonet base type indicates how it physically mounts in compatible housings. As always, verify that your fixture, wiring, and driver configurations support 120–277V input and that the maritime or exterior environmental ratings align with your site requirements. This retrofit’s inclusion of a support harness can simplify installation and reduce handling concerns during replacement projects.
