Sylvania LED downlights are highly efficient and affordable. They offer both four inch and six inch LED modules designed to retrofit into existing housings or easily install in new construction applications. Sylvania currently offers two warm white color temperatures to choose from, an incandescent-like 2700K and a more halogen-like 3000K. The four inch Sylvania RT4 downlight is one of our favorites. It's one of the first LED modules in the four inch size with the capability to retrofit into existing housings while providing an outstanding amount of light. Together, the RT4 and RT6 LED downlights allow you to mix and match can sizes for that perfect combination of look and light in your home.
