Thanks to the Dim-to-warm function, the brightness of the lamps can be adjusted to your desired level. For example, you can dim the light from warm white light of 2700K to extra warm white light of 2200K or from 5000K (white light) to 2000K (warm white). This gives you the flexibility to use the lamps as mood lighting, but also to create more light. The lamps are dimmable with our 20 - 400 watt plug-in dimmer, among other things.
