There are more and more LED bulbs with the traditional A19 shape that will screw into Edison sockets. But the "snowcone"-shaped bulbs give off most of their light on one side, making them suitable for a gooseneck desk lamp or overhead fixture, but not optimal for a desk lamp. This is the Pixi LED bulb where you can see how most of the light is coming from the top. This 40-watt equivalent consumes 6.5 watts and has a color rendering index of 90.
