Philips Professional lamp CorePro LED linear R7S 118mm 14-100W 830 DLED light source, warm white. The CorePro LEDlinear R7S from Philips is a retrofit solution as a replacement for conventional double-ended R7S rod lamps. Its all-round diffused light is comparable to that of a halogen lamp. Install the LEDlinear R7S in a dimmable luminaire and enjoy a cosy atmosphere thanks to the dimmability of the light source. Protect your eyes, the environment and your wallet with LED lighting. Benefit from longevity and energy efficiency: LEDs (light-emitting diodes) have the advantage over conventional light bulbs that they do not generate heat, but convert most of the energy into light and therefore only consume a fraction of the electricity. In addition, LED light sources are extremely robust and do not need to be replaced for a long time. Because LEDs are flicker-free and have a high colour rendering index, their light is always pleasant for your eyes. Objects that you highlight with LED lighting appear in their true, natural colours.
