Rigid Radiance Plus Sr-Srs Rgb. The SR-Series PRO LED Light Bars provide a sleek, low profile lighting solution that measures less than 2” tall. Thanks to improved LED technology, the SR-Series PRO now gives more light output than ever before with up to 111% more raw lumens. As the name implies, the SR-Series PRO uses a single row of LEDs with your choice of Hybrid or patented Specter optics in a variety of beam patterns. Suited to applications where space is limited, the SR-Series PRO is a powerful light source built to project light at extreme distances while consuming very little power. Available in a broad selection of lengths and configurations, these LED light bars can be used on virtually any application, whether it’s an off-road vehicle, industrial, agricultural, or marine. RIGID’s SR-Series PRO lights utilize extruded aluminum housings and are available with either a black or white durable powder coated finish. Along with improved LEDs for more output, the SR-Series PRO benefits from new branding and blacked-out circuit boards for a more refined look. They feature the same stronger build quality as the rest of RIGID’s lighting products, providing reliable and efficient lighting on demand.
