This short guide will help you understand the difference between lumens and Watts.
The term lumens defines a measurement of light. Lumens is a standardised international standard for measuring light being emitted by any source. One lumen is the amount of light emitted in a solid angle of 1 sr, from a source that radiates to an equal extent in all directions and whose intensity is 1 cd.
The term Watt is the international standard for measuring power ( energy per unit time)
Lightbulbs were traditionally rated by the amount of power they consumed, the higher the number on the box, the greater the light produced by the lightbulb. The same logic applies with lumens but the numbers are far greater. If you were to buy a 100 lumen LED lighting solution, you would have a light source equivalent to a candle, however a 100 watt lightbulb would illuminate a huge room brightly. To achieve the same lighting using LED lumen measurements you would need around 1600-2000 lumens.
The problems in translating the difference between lumens and watts arises when trying to convert watts to lumens or vice versa. This is because the two measurements are completely different. One is measuring the power consumed the other is measuring energy being produced and on a completely different scale.
We hope this helps you choose the most suitable LED Lighting system for your home.
