Benefit from longevity and energy efficiency: LEDs (light-emitting diodes) have the advantage over traditional incandescent bulbs of not generating heat, converting most of the energy into light, and thus consuming only a fraction of the electricity. Additionally, LED bulbs are extremely durable and do not need to be replaced frequently. Since LEDs are flicker-free and have a high color rendering index, their light is always pleasant for your eyes. Objects illuminated by LED lighting appear in their true, natural colors. SceneSwitch - three light moods in one lamp. Change the light mood as often as you like with Philips SceneSwitch bulbs. The control works through any regular light switch, even without a dimmer. By repeatedly pressing the switch, you can choose between three moods: 100%, 40%, or 10% brightness. At the same time, the light temperature becomes warmer at lower settings. Thanks to the integrated memory function, the last selected light setting is saved even after longer off periods.
