Shallow Plenum Recessed Downlight Options
A Closer Look at Shallow Plenum Lighting Solutions
Shallow Plenum Recessed Downlights: A Closer Look at the Options Architectural lighting design choices are often limited by a project's technical installation and hardware requirements. One of these limiting requirements is a shallow plenum. When the lighting designer and installers have to contend with a shallow plenum, it can negatively impact the lighting designer's creativity and artistry in planning a successful project where the architectural details and atmosphere of a space is shown off.
Having more options and making the right choice for your shallow plenum project are made possible by the wide range of options available with CSL Lighting's Shallow Plenum lighting products. Even for plenum spaces as low as 2 ½", CSL's range of fixed and adjustable shallow plenum recessed downlights give you limitless design choices with powerful lighting capabilities.
Fixed or Adjustable Shallow Plenum Lighting
Let's talk about light. At the center of every CSL shallow plenum lighting product is a high-performance LED module engineered with enough power and lumens to fill the entire room with quality light, down to the floor through CSL's patented Silent Vu
™ optic system - designed to remove harsh glare and provide perfectly soft, even light throughout the space. Each system offers interchangeable optics to create various distribution patterns and media options offering total light control for general, task and accent lighting. Housings are easy to handle, easy to install and ideal for commercial and residential projects.

CSL's patented technology allows you to have an easily adjustable lens that shifts a focused, round beam of light in any direction with a touch of the finger from below the ceiling, providing 45° tilt and infinite rotation. The collar accommodates for various ceiling thicknesses/materials and provides a perfect fit between the optic and trim for a superior look below the ceiling. Round or square trims offer exceptional quality with a traditional flange or modern flangeless style trim and a standard or baffle reflector in 4 different powder coated finishes. CSL 3" Adjustable Lens Recessed Downlights are Chicago Rated, with zero cut off.
