196led column led bulb,LED light bulbs give off directional light, so the light goes where you aim it. LED bulbs are closer to the color of daylight, which new studies suggest is good for staying alert. Our LED light bulbs can be used to replace your standard fluorescent or halogen light bulbs. The bright, white LED light produced by our LED Light Bulbs works especially well for task lighting and reading light. LEDs not only produce light more efficiently, they also have a tiny mirror that reflects light in one direction. A more directed light means less wasted light.
