Your Guide to LED Lighting
What is LED (Light Emitting Diode)?
Is a device consisting of semiconductor that emits light energy when an electrical current passed through it. LEDs can be used for a wide range of lighting applications. They are frequently being used to light homes and other spaces. They also popularly serve as indication lights just like the little glow you find in your remote controls. It is predicted that LED lights are the future for energy efficient home lighting.
THINGS YOU NEED TO KNOW
What is a Lumen?
For years, people have chosen light bulbs by wattage, learning over time about how bright a 40-watt or 60-watt bulb is. But wattage tells how much energy a bulb uses, not how bright it is.
With LED light bulbs designed to use less energy, wattage is no longer a reliable way to indicate a light bulb’s brightness. Brightness is measured in Lumens. With LED spotlights there is more to it than a direct lumen value comparison with the equivalent. The superior light quality given off by LEDs and much lower bulb degradation rate over time must also be taken into account. This is why the Lumen output for a 50-watt replacement LED spotlight is often less then quoted for a 50-watt halogen spotlight.
What does voltage mean?
This is a measurement of the volts required to operate the bulb. The standard for the UK is 240 volts. This means you can plug all 240v rated bulbs directly into existing fittings without changing any of the electrics.
What does colour temperature mean?
Colour temperature is a measure of how warm or cool the light is given off by bulb appears. ‘Warm’ colours appear tinged with yellow and generally feel soft and suitable for areas of comfort. Cool colours are tinged with blue and appear whiter, making them a more ‘honest’ and unforgiving light more suitable for bathroom or working environments than relaxing. Colour temperature is measured with Kelvin (K). The lower the colour temperature value in Kelvin, the warmer the colour so higher value refer to cooler colours.
What does the Beam Angle mean?
The Beam Angle is how wide the light is spread from the lens of the bulb. If you have a very narrow beam angle your light will be projected like a handheld torch whereas if you have a wide beam angle, it will be much softer and spread like a traditional bulb. Wide beam angles are best for living rooms, dining rooms and bedrooms where you are looking for a softer light and narrow beam angles for targeting specific areas or for decorations.
Direct Replacement Questions
My dimmer switch isn’t working with my LED lights?
This may be due to a couple of reasons:
1) Your LED bulbs may not be dimmable. Not all LED light bulbs have the ability to dim so you must make sure that your bulbs are the dimmable type.
2) Ensure that you have an LED-compatible dimmer switch. Standard dimmer switches do not work with LED bulbs. Dimmable LED bulbs will only operate effectively with a trailing edge LED dimmer switch.
Why do I need an LED-compatible transformer?
You may only need a transformer if you are buying 12v bulbs – MR16, G4 and MR11. All 240 bulbs do not require a transformer. Standard electronic transformers can cause certain types of LED bulbs to flicker, resulting in permanent long-term damage to the LED bulb itself. This problem is most evident in 12v MR16 LED bulbs where a standard transformer does not provide a smooth flow of current, causing flickering problems. To avoid damaging your new LED bulbs it is always best to use LED drivers/transformers.

Facts About LEDs
The average UK household can save over 5 tonnes CO2 emissions by replacing their standard lighting with LED alternatives.
