Desk lamp lighting incumbent

LED light sources give off directional light, which makes LED lighting well suited for retail stores or down lights above a kitchen counter. But what about for a desk lamp where you want an even dispersal of light so you can read?

Efficient and long-lasting LED bulbs now coming to market are designed to disperse light better than down lights, but there are still some limits to what they can do. This slideshow will compare how light is dispersed from a desk lamp using a few different bulbs.

Pictured here is a 75-watt incandescent bulb. Looking at the lamp shade and lamp itself, you can see light is given off in all directions.
