Watts to Lumens conversion table

Until you’re comfortable using lumens to calculate how much light a bulb will produce, use the table below as a guide:

Colour Temperature and Colour Rendering

There are 2 very important aspects of light relating to colour which are often referred to but not always understood. 

Both properties of lamps have very different meanings and implications.

Lumens (indicated by lm) are a measurement of the total amount of visible light to the human eye from a light source. The higher the lumen rating, the brighter the luminaire will be.

Watts is a measurement of the energy used to power the luminaire. The higher the bulb wattage, the less efficient the bulb is in conserving energy. 

In simple terms:

  • More Wattage = More Money
  • More Lumen = Brighter

Buy lighting based on Lumens
NOT Watts

For years, buying incandescent lighting was based on wattage. But as energy-efficient bulbs like CFL’s and LEDs have become available, watts have become an unreliable measurement for choosing the right bulbs.
Instead of just focusing on wattage, you should consider the brightness of the LED bulbs which is measured by lumens.
