The clear glass cover and visible filament give this LED bulb the look of a classic incandescent bulb. Thanks to the dim-to-warm function, the light colour changes as you dim the bulb. At full brightness, the bulb emits 4000K white light; when dimming, the light becomes increasingly warmer down to 2200K. This way, this filament bulb combines bright functional light with warm atmospheric lighting.
With the dim-to-warm function, you adjust both the brightness and light colour at the same time. During dimming, the light colour gradually changes from 4000K to extra warm white light of 2200K. This allows you to use the same bulb for both brighter light and warm, atmospheric lighting.
The bulb is dimmable with a compatible external LED dimmer (not included).
