http://www.1800lighting.com In this instructional video, WAC Lighting specialist Devin Horzempa goes through the steps of changing the lamp in a recessed downlight and provides some general tips when changing WAC lamps . Use a secure ladder to access your recessed downlight and always make sure anything from WAC Lighting is turned off before you try to remove it and while changing WAC lamps. The HR-423 recessed downlight, as with most WAC Lighting products, is easy to install and even easier to maintain. When changing WAC lamps make sure to follow the instructions correctly and take all safety precautions.
