Thomas Research Products (Hyntley, IL) has introduced a new step-dimming module that offers easy bi-level dimming control for LED luminaires. The SD1 device works with two standard wall switches to allow bi-level step-dimming of LED luminaires. This module is suitable for situations where quick switching between 100% and 50% output is needed, such as occupancy sensor applications. It works in conjunction with any 0-10V dimmable LED driver from any manufacturer.
