With Philips WarmGlow LED lamps, you can dim normal everyday lighting to the warm tones of traditional lamps. The more you dim the light, the warmer the tone of the light. This distinguishes them from conventional dimmable LED lights, which only reduce brightness when dimmed. WarmGlow lamps now also have a marked color rendering index of Ra 90, which matches natural light and thus helps you see the colors in your home as natural. Whether you spend a cozy evening at home in the corner of the sofa or start the day with refreshing morning light, the light from Philips WarmGlow LED lamps is just right for your needs.
