Most of our residential bulbs are dimmable, with the exception of the bulbs described as Hyperselect. All LED bulbs, regardless of manufacturer, need to be paired with an LED-compatible dimmer switch that is ELV (Electronic Low Voltage) in order to work correctly. This is because regular incandescent dimmer switches do not regulate the flow of electricity properly, as they are made to work with bulbs that require more energy to operate.
The majority of our commercial products are not made to be dimmable. There is a few that in fact are, for example, Troffer Panels, UFO High Bay, Premium Shoebox, etc. On those you will need to get a compatible 0-10v dimmer.
