Things to look for when shopping for LED light bulbs:
1. Look for the U.S. Department of Energy’s ENERGY STAR logo for guaranteed color, quality over time, steady light output over the lifetime, high efficiency, and a warranty.
2. Lumens: The higher the number, the more light is emitted.
3. Lumens per watt (lm/W): The higher the number, the more efficient the product.
4. Watts: The lower the wattage, the less energy that is used.
5. Correlated Color Temperature (CCT): Cool white light is usually better for visual tasks. Warm white light is usually better for living spaces because it casts a warmer light on skin and clothing. Color temperatures of 2,700 – 3,600 K are recommended for most general indoor and task lighting.
6. Coloring Rendering Index: The higher the number, the truer the appearance of the light.
