The Residential-Grade Downlight: Compact Fluorescent, LED and LED Retrofit
With energy consumption (efficacy), lamp-life and longevity of design rising on the priority list, even the simplest of residential projects are being pushed towards non-incandescent sources. The lighting program in residential spaces is often driven by greater concern for color rendering, warm color temperatures, minimizing glare and creating softer light textures through the use of diffusing lenses. Recessed luminaires for residential projects must commonly provide an insulated ceiling (IC) rated housing (see chapter 24). These criteria all add up to a fairly specialized product, worthy of its own family. Commonly-specified
high-efficacy, residential luminaire are available from Lightolier, Iris, and Capri.

The Continuous Linear LED Luminaire
Long, continuous lines of light are fairly common design feature in contemporary environments. The diminutive linear sources that create these shapes of light can be smaller than 1” x 1” in profile and are often flexible and can be cut to any length in the field. These luminaires often operate at low- voltages that require a remote transformer or “driver”. These luminaires can serve in coves, slots, niches, and even as under cabinet luminaires. Many mount into slender channel brackets. Some even mount with simple sticky tape. Some commonly-specified versions of this type of luminaire are from Tivoli, Solavanti, ColorGlo, and Tokistar.
