The Philips 4.5-watt medium-base candle bulb produces the same light as a 40-watt incandescent bulb while using a fraction of the electricity. This bulb also has Warm Glow technology which warms the color temperature as the bulb is dimmed for a more natural light. The 25,000-hour life will eliminate the hassle of repeated re-lamping. This high-efficacy LED light contains no mercury, emits virtually no UV/IR light, doesn't fade colors and provides an even, diffuse light source.
