Warm Glow effect 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 turn on instantly with energy-efficient steady, natural light 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. A15 soft white light bulbs are perfect anywhere you need a balance of clarity and warmth with the flexibility of dimming in a slightly smaller bulb. The E26 medium base fits standard fixtures on pendant, vanity, and bare lamps, providing soft white light with warm dimming. This pack of 10, A15 Philips LEDs comes with a 10-year warranty. Each bulb is expected to deliver a lifetime of up to 25,000 hours and well over 10 years of use (based on three hours per day) saving you the cost and hassle of frequent bulb replacement.
