The Great Value Dimmable Light Bulb (LED BR30) is suitable for use in the home, the workplace and elsewhere. It works with dimmer switches, allowing you to choose a high- or a low-light level, whichever is needed. Turn it up for bright illumination or down in order to have low lighting for a presentation on a projector or monitor. This Great Value light bulb shines with a soft white light and uses only 10 watts of energy while giving off a 65-watt equivalent. The efficiency of the bulb aids in saving on energy costs--which is also eco-friendly.
