Philips Clear Classic A19 LED light bulbs provide 800 lumens of soft, glowing white light, equivalent to 60-watt incandescents with 80% less energy use. 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 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. Philips Clear Classic bulbs offer the familiar look and feel to the traditional bulbs, perfect fit for your fixtures. With a standard E26 medium base these bulbs can be used in most household fixtures. This pack of 8, A19 Philips LEDs comes with a 10-year warranty. Each bulb is expected to deliver a lifetime of up to 25,000 hours and over 10 years (based on three hours per day), saving you the cost and hassle of frequent bulb replacement.
