Solais brand lamps were designed to be truly backwards compatible. They were designed to work on standard incandescent dimmers (forward phase chopped waveform). This means that you do not need to update the dimmer you have been using for the last 80 years to work with Solais products. For a list of dimmers that have been tested with Solais products, please visit our dimmer compatibility list under “resources”. If you can’t find a dimmer you are looking for on the list, contact us for compatibility.
