Get a longer lasting, safe, and affordable alternative to incandescent or CFL light bulbs using this 6-Pack of 10-watt A19 LED Bulbs from Monoprice! This 120-volt bulb uses only 10 watts of power, but produces 810 lumens of light energy at 4400K, equivalent to a standard 60-watt incandescent bulb. It uses the E26 "medium" Edison screw base, which is the standard home screw-in bulb type we're all used to. This indoor bulb is 2-1/8" in diameter and 4-1/2" tall. The bulb features a shatter resistant polycarbonate lens, which is designed to withstand ordinary drops and falls, and a 100% aluminum heat sink. The bulb uses the superior Japanese-made Nichia diodes, is rated for up to 40,000 hours of use before failure, and carries a three year replacement warranty. The bulb generates light in the 4000K range, which generates a bright, white light that is ideal for office and showroom use. This bulb is not designed to be dimmable. While it may be physically dimmed in some light fixtures, doing so can damage the bulb's internal circuitry and severely reduce its expected life span. Each order includes six, individually packaged bulbs. Monoprice warrants these bulbs for a full THREE (3) YEARS and will provide a new replacement for any bulbs that fail due to defects in materials or workmanship during the warranty period.
