What are ‘Lumens’?

  
Lumens, what are those? You may have heard the term before, but not really sure what it means. Don’t worry – we are here to help clear things up! 
  

The Definition of Lumens

  
In short, the lumen output describes how much light a lamp or LED will produce. So an LED strip which produces 700 lumens per metre will give you more light than a strip which gives 350 lumens per metre. Most of us are still stuck in the times of halogen or incandescent lighting and confuse wattage with how bright the lamp will be, however, wattage is just a measure of energy use.
  

How Many Lumens do I Need?

Finding out just how much light you need to illuminate a room can actually be very simple. The type and size of the room you are trying to light will determine the lumens needed for sufficient lighting. There are many different rooms in a home from bathrooms and kitchens to living rooms and bedrooms. You usually would require more light in a kitchen due to food preparation and less in a bedroom as it’s where you go to relax! To roughly figure out how much light you need in a room, firstly you need to work out the square footage. So if it’s a 5 x 5-metre room, it will be 50 square foot. Then all you need to do is multiply the square footage of the room by 1.5 and it’ll give you the wattage needed to light the room. Clever huh? 
  
Example: 5 x 5 = 50 x 1.5 = 75W (roughly 1125 lumens). So, you’ll need to use roughly 15W of LED strip to light a room of this size.
