A comparison of LEDs

To get a better idea of how different LED lights compare, I put three different bulbs in the same place and took pictures. This isn't a very scientific comparison, but it shows some of the different qualities of different LEDs, which of course apply to other types of lights as well.

On the left you can see a 40-watt equivalent LED bulb from Lighting Sciences Group that consumes fewer than than 8 watts. The color temperature on this bulb is 3,000 Kelvin, which gives off a white, rather than yellow, light.
