Types of Bulbs
CFL and LED bulbs are available in a variety of shapes and sizes for any application- including recessed cans, track lighting, table lamps, and more. You can even find certified bulbs that are dimmable. Use this chart as a guide to finding the right bulb for your light fixture and remember to always check the packaging for proper use.
Watts a Lumen?
For brightness, look for lumens, not watts. Lumens indicate
light output. Watts indicate energy consumed. Certified bulbs provide the same brightness (lumens) with less energy (watts). Use this chart to determine how many lumens you need to match the brightness of your old incandescent bulbs.
Certified bulbs are available in a wide range of colors. Light color, or appearance, matches a temperature on the Kelvin scale (K). Lower K means warmer, yellowish light, while higher K means cooler, bluer light.
