How bright are led light bulbs?
Led bulbs available for standard fixtures vary in brightness from less than 50 lumens up to about 1200 lumens. The brightest led bulbs for standard fixtures are the floodlights and spotlights. The brightest of these uses about 25 watts and produces light comparable to a 120-watt incandescent.
The brightest LED bulbs with approximately the same size and shape as ordinary incandescent bulbs produce up to 600 lumens. With a few exceptions these bulbs are somewhat directional so they are most effective when pointed at the area to be illuminated.
