You can use our lumens to watts calculator to calculate the efficiency of different bulbs and low wattage LEDs based on their brightness to power ratio, known as luminous efficacy, where the brightness of the light is in lumens and its power, in wattage. You can then compare your LED bulb...
In the past, we commonly bought conventional bulbs on the basis of wattage. We knew that a 75W lightbulb produced more light than a 40W bulb. Over time, the technology involved in lightbulb manufacturing has improved to allow the production of more energy-efficient bulbs (CFL, LED). These ...
You can also use thelumens calculatorbelow the table of contents. If you are new to this type of calculation, read the guide below the calculator to understand the difference between wattage, lumens and other concepts that play a role in adequately lighting for a space. Table of...
Unlike the other terms, wattage refers not to the amount or quality of light emitted, but rather to the amount of electrical energy poured into the light source. A watt is a unit of measurement for gauging energy consumption. Because some light sources consume energy more efficiently than other...
