Watts vs Lumens
Many people still use the old rule of thumb for a medium size room you use a 100w light bulb. This refers to the old incandescent bulbs that use 100 watts of electricity to give you a certain light level.
Light levels are measured in lumens. A 100 watt incandescent light bulb gives approximately 1600 lumens of light. So look for the Lumens on the packaging and not the wattage.
You can compare your current light bulb against our Energy Efficient LED bulbs listed below.
