What you need to know about LED lights

LED is continuing to grow and is about to become dominant in the lighting market. We explain the key points you need to know about this emerging technology...
The lighting market is continuing to grow. According to Lux, the lighting market was worth £2 billion in 2015, a 13% increase on the previous year.

One of the reasons for this continued growth is the rise of LED lighting. Boasting energy saving reductions and a longer life span compared to traditional technologies, the popularity of LED is growing by the year.

As a topic we have previously discussed on Circuit Break, there are signs that more sectors, such as office and retail environments, are now getting involved in adopting this technology. LED technology is even being adapted to be used in a variety of applications to replace aging and costly technology with the aim of benefitting from the cost effectiveness and longevity of LED.

LED lighting is a solution you may be hearing more about and you may be wondering whether this form of lighting is right for you and your next project? With further verification being offered on products to put the market at ease, now is the time to explore LED technology further.

What is LED?

LED stands for ‘lighting emitting diode’. What makes LED technology different to traditional lights such as incandescent and compact fluorescent bulbs is that they emit light in a specific direction. LED’s create light with the use of a semi-conductor rather than a thin wire filament.

Using this technology, means these type of lights use electricity more efficiently. As such a higher percentage of energy goes into creating light rather than heat (as in the case of incandescent lamps) with overall less Watts being used to create an equivalent amount of light. Although LED lights are seen to be more expensive compared to traditional lights the price of these solutions has been falling significantly in recent years.

What do you need to know about LED Lights? Here are five things:

1. They use less energy

According to Which, LED lights are the most energy efficient means of illumination and use 90% less energy than traditional incandescent lights.

An example from EON found that when they upgraded to LED lighting, amongst other lighting solutions, they benefitted in energy savings of up to 82%.
2. LED brightness is measured in Lumens, not Watts

When you usually buy a lamp, you will look at the wattage to determine the brightness. However, LED’s are measured differently. Wattage actually shows how much energy is being drawn, rather than the brightness.

For example, a 60w incandescent bulb is only 8-12 watts on an LED bulb.

When looking at the Lumens of a LED bulb, a 1600lm bulb will only take up 16-20 watts compared to 100w of an Incandescent blub. The amount of energy LED bulbs use to illuminate is significantly lower compared to other solutions.

3. LED lights are not always the same colour

When you buy an LED light, you may presume that like most traditional lights the colour will be the same. However, LED lights can differ.

Some LED lights can produce a cool blue light whilst some can display a warm light that you may be used to from traditional bulbs. You may want to check with your client that they’re happy with the shade of light emitted from your recommended fitting before installing multiple lights.

The light emitted in measured in Kelvin, a lamp with a rating of around 2700 – 3000k is the warm light you would normally associate with an incandescent lamp.
4. Time is on LED’s side

Depending on which type of LED bulb you purchase, they can last between 25-30 years. Many LED’s can last up to 50,000 hours, which can be 8-10 times longer than an incandescent.

When you take into account that lighting takes up at least a quarter of energy consumption in most sectors, the savings a client could achieve over this period time could be utilised elsewhere to help them create an energy efficient environment for their building.
5. Hager are part of the LED revolution

Here at Hager we know that LED lighting is on the rise. We have launched a range of outdoor LED lights with integral PIRs which will be perfect for your next application.

Our decorative LED lamp with PIR can remain on for a set period between 5 seconds to 15 minutes if no further motion is detected, switching off to avoid using unnecessary energy.

Our LED floodlight with motion detection automatically illuminates when somebody enters the detection area and switches off after a set period of time to avoid waiting energy. This solution is suitable for a range of applications including commercial, education and residential projects.

Additionally, with an innovative installation technique using pin-contacts and the ability to set the sensors right in front of the device or via a remote control, our outdoor LED lights are ideal for your next project.
