Recessed ceiling downlight KETRA D2

LEDroundindoor

Overview
The Ketra D2 fixed remodeler downlight brings full-spectrum Natural Light to 2 in architectural remodel installations. Built for direct installation through finished ceilings, this non-IC housing fits a standard 3.125 in cutout (4 in for flangeless mud-in) and provides consistent downward illumination. The integrated 4-channel light engine supports a continuous CCT range and wide saturated color capability while Color Lock maintains color consistency over the fixture life.

Highlights

• 4-channel engine: full-spectrum natural white and 16.7 million colors, including pastels and saturated hues
• CCT range 1,400K–10,000K for extended white tunability
• Vibrancy control to adjust spectral composition without changing CCT or intensity
• Color Lock auto-calibration to preserve color accuracy over time
• Designed as a fixed 2 in downlight for remodeler installations with reduced ceiling work
• Installs through a 3.125 in cutout (4 in for flangeless mud-in), minimizing demolition and install time
