Light Efficient Design LED-8100-22K LED SOX35 Retrofit Lamp - 20W - 2200K - 2,030 Lumens - 120-277V

The Light Efficient Design LED-8100-22K is a retrofit LED solution designed to replace aging SOX lamps in outdoor and area-lighting applications. At 20 watts, it provides approximately 2,030 lumens with a 2200K color temperature, offering a warmer, amber-leaning light that can help maintain dark-sky visibility while delivering the performance of a traditional 35W low-pressure sodium source. The design emphasizes directional light output to minimize stray illumination and improve efficiency in retrofit installations.

Key construction and design features include an innovative aluminum heat sink and active cooling, which help manage heat to sustain performance and longevity. The unit includes a support harness and is rated for operation across a broad input voltage range of 120–277V, with a claimed 50,000-hour rated life. The LED driver is designed and specified for internal use, and the product supports surge protection up to 6 kV, aligning with common reliability expectations in public and industrial lighting environments.

In terms of practical use, this retrofit is intended to replace a 35W SOX lamp, enabling energy savings and compatibility with existing fixtures configured for SOX-style lighting. Its compact form—approximately 12.21 inches in length and 2.83 inches in diameter—along with the Bayonet lamp/base type suitability, supports straightforward installation in compatible luminaires. Consider verifying fixture compatibility, mounting provisions, and electrical wiring to ensure proper fit and performance in your specific application.
