LED Lighting Modules

There has been much attention in the media given to the lighting revolution that is the LED. Many predict that LEDs will be the dominant technology lighting our homes within a few years and companies around the world are investing vast sums in research and development in this area.

What is an LED?

LED stands for Light Emitting Diode and was invented nearly 50 years ago. You would most likely recognise these early LEDs as low brightness indicator lights on such things as audio equipment or as used in solar garden marker lights.

The LED has no filaments or gas inside to generate the light. They work owing to the movement of electrons in a semiconductor material which generates photons or light.

Why are they so special?

LEDs are extremely efficient and can generate more light per unit of electricity than most technologies. They don't need mercury to generate light and last up to 50 times longer than a conventional incandescent lamp and around 5 times longer than a compact fluorescent energy saving light bulb.

So what's the catch?

Like all products there are good ones and bad ones. As the technology develops many more companies are offering LED products for sale and there are plenty of rogue claims being made for the performance of poor quality products.

Always look to buy from a reputable manufacturer and look for evidence that the performance has been verified by
an authority or third party. Buying poor quality LEDs is a false economy. We would recommend looking at the light
output rather than the wattage to judge the lamp.

Where should I use them?

This depends on a number of factors. In order to benefit from the low energy use and long life you should identify areas of the home that are lit for long periods. Kitchens and living rooms are typically the ones where the lights burn longest. Bathrooms and utility rooms tend to have lower use. LED under cupboard lights are ideal in kitchens owing to the low heat output. Most people will have seen solar powered garden lights which emit a low brightness glow to mark pathways and new developments are bringing good alternatives to conventional outdoor floodlights.

What about light quality?

Most people like the warm light given off by the old fashioned incandescent light bulbs and the more recent halogen alternatives. LEDs come in a variety of colours from warm white to cool colours so be sure to choose a colour to suit your needs. Cooler light is often used in work areas as it is a closer simulation of daylight whilst warmer colours are more likely to be used in areas used for relaxation. Interestingly studies have shown that older people prefer warm coloured light whereas younger people are satisfied by the cooler colours.

Colour temperature as it is known is displayed on the packaging of many light bulbs and is measured in Kelvin (K).
Lighting with colour temperatures of around 5000K are at the cooler end of the spectrum and give a bluish white
while those around 3000K and less are warmer colours. In the case of directional light bulbs such as those fitted in down lighters it is important to consider the beam angle. A wider beam angle will give a more even spread of light over a wider area and several of them will overlap to improve this effect. A narrow beam angle will produce a spot effect or a small pool of light. Decide which effect you want to create and buy the appropriate lamps.

Check when replacing your light bulbs with LED that they offer the same performance not just in terms of beam angle but in light output. The amount of light a light bulb emits is measured in lumens and is increasingly appearing on packaging so you can compare like for like. A 60W filament lamp typically produces around 700 lumens so you need to look for a similar output from an LED product to provide the same amount of light.
