These bulbs fit standard medium base (E26) fixtures with the look and feel of a classic bulb. Not for use with Philips HUE products. 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. 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 4-pack of A15 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.
