Satco S16511 Led Circline Lamp 16W T9 Selectable Cct

Product Description

The SATCO S16511 is a 16-watt LED Circline lamp in a T9 circular form factor, designed to replace traditional fluorescent circline lamps in compatible luminaires. It uses a G10q base and operates across a wide input voltage range of 120 to 277 volts, making it suitable for both residential and light commercial applications. A built-in selectable CCT switch allows the installer to choose between 3000K, 4000K, and 6500K color temperatures at the time of installation, eliminating the need to stock multiple SKUs for different lighting environments. Electricians and lighting maintenance technicians are the primary trades handling this retrofit.

This lamp is intended for use in circline fixture applications where a direct LED upgrade from fluorescent T9 circline sources is needed. The wide voltage range supports installation in standard 120-volt residential circuits as well as 208-, 240-, and 277-volt commercial lighting circuits. The selectable CCT feature makes it practical for facilities that standardize on a single replacement part across spaces with different color temperature requirements, such as offices, storage areas, and retail back-of-house spaces. Each unit is sold individually.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize the fixture and verify voltage is absent before handling the lamp or base connections. Confirm the fixture is rated for LED retrofit lamps and that the G10q socket is in serviceable condition before installation. Set the CCT selector switch to the desired color temperature prior to final installation, as access may be limited once the lamp is seated.
