Understanding how many watts does a light bulb use is crucial for optimizing a home's energy use and achieving the right brightness. This article focuses on the relationship between wattage, brightness, and energy use across different types of bulbs, including traditional incandescent and energy-savi...
Watts: What’s the Difference? When it comes to choosing the right light bulb, understanding the difference between lumens and watts is crucial. While lumens measure the brightness of a bulb, watts indicate the amount of power it consumes. Let’s delve deeper into the distinction between these...

Light bulb lumens Lumens refer to how much light a bulb gives off. If a bulb has more lumens, it will have a brighter light. The U.S. Department of Energy recommends considering lumens instead of watts while shopping if your main concern is how dim or bright your home lighting will b...
Instead of focusing on watts in, you will need to focus on the light output, which is measured using the lumens metric. Not sure how many lumens you need? You can estimate what you need based on what you had installed before switching to LEDs. This can be calculated using an approximate...
Basically, instead of emitting light from a vacuum (as in an incandescent bulb) or a gas (as in a CFL), an SSL emits light from a piece of solid matter. In the case of a traditional LED, that piece of matter is a semiconductor. Stated very simply, an LED produces light when an ...
