Triple-tube CFL lamps deliver efficient, compact fluorescent lighting in a 3U configuration that fits a wide range of commercial downlight, wall-sconce, and task-lighting fixtures. With wattages from 13W to 55W and color temperatures spanning 2700K warm white to 5000K daylight, these lamps suit offices, retail environments, hotels, and multi-unit residential properties that need reliable illumination without a full fixture replacement.

The triple-tube design packs more tube surface area into a small envelope, producing strong lumen output for the lamp's size. Most models use a GX23, GX24, or 2G11 pin base and are designed to operate on a matched CFL ballast. Check your existing fixture's ballast type before ordering to ensure compatibility.

RelightDepot stocks triple-tube lamps from trusted commercial brands at competitive contractor pricing. If you are phasing in an LED program over time, our Quad-Tube CFL Lamps offer even higher lumen output for larger fixtures, while our LED Light Bulbs provide a long-term energy savings path with no ballast required. Browse the full Compact Fluorescent Lamps catalog to find the right CFL type for every fixture in your project.
