In principle, if you NEVER dim the light, a CFL should work appropriately. However, because of the risk of users dimming the switch even accidentally, this is not something we recommend. Additionally, using a CFL on a dimming switch will likely void the product warranty even if the switch is never dimmed. If you wish to use a CFL on a dimmer, we recommend that you look for bulbs that indicate they are compatible with dimmers on their packaging.
