With this LED bulb from Philips, you are choosing a light source that emits warm and atmospheric light. The WarmGlow technology not only adjusts the brightness of the light when dimming, but also the colour temperature; the more the bulb is dimmed, the warmer the light becomes. In addition, the LED bulb is also very energy-efficient. This LED bulb with a large fitting (E27) produces a warm white light with a colour temperature that can be adjusted from 2700K to 2200K. The maximum light output is 806 lumens, with a consumption of 5.9W (136 lumens per watt). The LED bulb has a clear finish so that the LED filament is clearly visible and is reminiscent of a traditional light bulb. This makes the bulb look good in both open and closed fixtures. The light emitted by the bulb also has a high colour rendering index (CRI value) of 90. This means that the light quality is high and the light colours look very natural.
