Designed to replace a 40W incandescent, this clear LED A-shape lamp replicates the appearance of a decorative filament Edison bulb. Classified as an A17 shape with a standard medium base and omnidirectional distribution, the lamp produces 310 lumens at 2700K with a CRI of 80-plus while consuming 4W. Instant-on at 120V AC with a built-in driver, it is not dimmable. Expected lifetime is 15,000 hours at operating temperatures from -20 C to 40 C. aamsco.com
