With Philips WarmGlow LED lamps, you can dim the everyday lighting to the same cozy tones as traditional light sources. The more you dim, the warmer your lighting will be. This is the difference to traditional dimmable LED lights, which only dim the light when dimmed. WarmGlow lamps have now been enhanced with a color rendering index of 90, which is comparable to natural light, so you can see the true colors in your home. Philips WarmGlow LED lamps have the right lighting for your needs, both when you're cozying up on the sofa in the evening and when you want a bright start to the day.
