Warm Glow dimming offers flicker-free, silent dimming that works with more dimmer switches than any other LED on the market. The more you dim, the warmer the light--from 2700- to 2200-kelvin just like traditional incandescent light bulbs. Best-in-class Philips LEDs provide energy-efficient, steady, natural lighting at 1/4 of the energy of incandescents, 1/2 the energy of halogens and with 10X and 4X the lifespan respectively. Philips LEDs are mercury-free so they don't contribute to harmful hazardous waste. Classic A19 soft white light bulbs are perfect anywhere you need a balance of clarity and warmth with the flexibility of dimming. The E26 medium base fits standard fixtures on pendant, vanity, and bare lamps, providing soft white light with warm dimming. This 4-pack of A19 LEDs is expected to deliver a lifetime of up to 25,000 hours and over 20 years based on standard usage of three hours per day, saving you the cost and hassle of frequent bulb replacement.
