How can I install LED lighting?

LED FAQ

• Light fitting types

  Most LED lights will come in a variety of fittings including Edison screw fix, Bayonet and GU10/16 styles, so in most cases you should be able to find a replacement light without having to replace the fitting.

• Dimmers

  Not all LEDs are dimmable. If you are looking to replace a dimmable light, ensure that the replacement is a dimmable type. If the product is dimmable, this should be mentioned in the product description.

• Colour temperature

  Colour Temperature refers to the hue or colour of the light produced from LED. It is expressed in ‘degrees Kelvin’. Warm white is the most suitable for residential purposes and is the colour band between 2,500 and 3,000 degrees Kelvin. Always check the colour of the light before purchasing; this should be listed in the product packaging.

• Colour Rendering Index (CRI)

  CRI is the measure of how well a light source can accurately display colours compared to natural sunlight. It is expressed as a percentage, the higher the number the better the visual perception of the colour. A CRI between 85 and 100 is excellent, a CRI between 60 and 84 is considered good, a CRI of 59 and under is considered poor.

• Lumens

  Light is measured in 'Lumens', which is the measure of the amount of light emitted. A high number of lumens mean it has a brighter light, where a lower lumen number is a dimmer light.

• Beam angle

  This is the outer angle of the light emitted from the light source when it is at 50% of its centre beam intensity. Halogen downlights typically have beam angle of 60^o and LED downlight globes have beam angles ranging from 20^o to 180^o, so check the beam angle before purchasing downlight replacements.

• Lifetime

  LED lights can last up to 50,000 hours; halogens have a lifetime of up to 5,000 hours.
