For many years we have become accustomed to buying incandescent light bulbs by their watt rating.
With the introduction of LED globes and technology, the way we have grown used to buying bulbs, is no longer valid. LED bulbs/globes use less energy (Watts) to deliver the same or higher amount of brightness or Lumens.
LED’s help save you electricity and money, by delivering sufficient light (Lumens) with less energy (Watt)
So what exactly are Lumens and what do you need to know in order to buy the correct bulb for your required application?
- Lumens is the measurement of the total amount of visible light that a human eye can see from a light source. The higher the lumen output, the brighter the light will appear.
- Lumens is the most important factor when choosing LED lights because it tells you how the light actually performs, regardless of the source that produced it. Therefore you can get two 4W LED lamps with two different lumen outputs, and two different prices. (TIP: be sure to compare lumens on packaging when selecting bulbs)
- One lumen is approximately equal to the amount of light put out by one birthday candle that’s one foot away from you.
- To help you get an idea of the lumen scale, a conventional 60-watt bulb puts out around 750-850 lumens of light. If you’re choosing bulbs for task lighting, look for bulbs with 1000 lumens or more.
How many Lumens do I need?
There is no firm answer – it will depend on a number of factors including; room size and shape, height of ceilings, colour scheme, type of lamps & fitting, task areas and needs of the user.
As a basic guide; below are the lumens required per Sq M for different room settings. In many cases a mixture of general and task lighting will be required.
