EcoSmart Selectable CCT A19 LED light bulbs offer three light color choices in a single bulb. Each LED bulb is equipped with three color temperature settings: 2700K (Soft White), 3000K (Bright White) and 5000K (Daylight). Simply use the switch directly on the bulb to select the desired color temperature and then install the bulb. Selectable color temperature technology removes the guesswork of choosing the correct color temperature for your space. Now you only need one LED bulb for all the rooms in your home. These A19 LED bulbs use only 13-Watt of energy to produce 1500 Lumens, which is equivalent to a traditional 100-Watt incandescent light bulb. LED lighting is not only the most efficient lighting technology, it is also the longest lasting. Each of these LED bulbs is rated to last for 15,000 hours of use. That's 15 times longer than the traditional incandescent light bulb. Improve the quality of light in your home and upgrade to energy efficient Ecosmart LED light bulbs today.
