Philips WarmGlow LED bulbs allow you to dim the light to more cozy tones, as you know it from traditional bulbs. The more you dim the light, the warmer it becomes. This sets them apart from regular dimmable LED bulbs where you only adjust the brightness. The WarmGlow bulbs are now expanded with a color rendering index of 90, which corresponds to natural light. This way, you can experience your home in its true colors. Whether you want to relax on the couch in the evening or need a bright start to your day, Philips WarmGlow LED bulbs have the right light for your needs.
