LED Lights - All you need to know
Choosing an LED light can be quite overwhelming as there are many different features to choose between. It can be difficult to differentiate between lumens, wattage, temperature and colour but all of these characteristics have their own purpose.
LED lights are a relatively new technology brought onto the market as a more energy efficient option that has a longer lifespan than halogen or incandescent globes. The estimated lifespan for LED globes is approx. 25,000-50,000 hours or up to 5 years! This is almost 50 times the lifespan of a halogen or incandescent globe.
What’s the difference between these globes?
Colour Temperature – Colour temperature is measured in degrees Kelvin and represents the colour of light that we see. 3000K is equivalent to a warm white colour and 5000K is equivalent to a cool white colour. Generally it comes down to personal preference as to which colour is more suitable, however it is not recommended to have globes of both colours in the same room as it can be very distracting to the eye.
Lumens – The lumens represents the brightness of the light. It is equivalent to the amount of light hitting a square foot of surface that is one foot away from the light source.
Wattage – Wattage is the term used to describe how much power the globe uses, for example a 20 LED globe will use approx. twice as much electricity as a 10W globe.
Lumens per watt – This measure shows the energy efficiency of the globe i.e. how bright the light is compared to how much energy it uses. For instance, an 810lm globe that has a wattage of 10W has an efficiency of 81 lumens per watt however a globe with the same lumens but a wattage of 5 has a much higher energy efficiency to achieve the same brightness.
The most important thing to remember when choosing between different LED globes is to choose the one that will suit your specific needs. There is no single globe that will be right for everyone so it’s vital that you choose the features that are most essential to you.
