Philips PAR30S LED spot light bulbs provide 750 lumens of bright white, dimmable light at a 35-degree beam angle, equivalent to 75-watt incandescents with 80% less energy use. Appropriate for indoor and outdoor use, these shorter PAR30 bulbs fit medium base (E26) fixtures and measure 3.5 inches tall with a bulb diameter of 3.66 inches. Philips LED dimming is flicker-free, silent, and tested work with more dimmer switches than any other LED on the market. The light dims smoothly from 3000-kelvin down to a glow with greater clarity than traditional incandescent light bulbs. Philips LEDs turn on instantly with energy-efficient, steady, natural lighting at 1/4 of the energy of incandescents, 1/2 the energy of halogens. Philips LEDs are mercury-free so they don't contribute to harmful hazardous waste. Philips LED bulbs last 10x longer than incandescents and 4X longer than halogens making them a great choice for landscapes and security devices in hard to reach areas-saving you the cost and hassle of frequent bulb changes. Not for use with Philips HUE products. Each bulb in this pack of four PAR30S Philips LEDs is expected to deliver a lifetime of up to 25,000 hours and over 22 years of use (based on three hours of usage per day), saving you the cost and hassle of frequent bulb replacement.
