Sylvania LED can lights are highly efficient and affordable. They offer both four inch and six inch LED downlights designed to retrofit into existing housings or easily install in new construction applications. The RT5/6 units are six inch lights which will fit into most five and six inch receptacles. Sylvania currently offers two warm white color temperatures to choose from, an incandescent-like 2700K and a more halogen-like 3000K. Together, the RT4, RT5/6 and RT6 LED downlights allow you to mix and match can sizes for that perfect combination of look and light in your home.
