How To Choose The Right LED Downlight

With a range of options available, it can be confusing to determine which light is right. See our easy guide below for help!


Energy saving lighting is about reducing the wattage used in a light fitting while maintaining similar light output. A standard halogen downlight uses 55 watts, while LED alternatives range from 4.5 watts to 14 watts.


Lumens measure the amount of light produced by a light source. It is equal to the amount of light hitting one square foot of surface one foot away from the light. The higher the lumens, the brighter the light.

Lumens per watt

This truly shows the efficiency of the LED product. For example a 200lm product consuming 3 watts of electricity = 66 lumens per watt. Lumens per watt vary from product to product depending on the LED chip used, how hard the product is being run, and the construction of the fitting and how effective the heat sink is at removing the heat.

Beam angle

When choosing the right LED lighting for the space, the beam angle is as important as the Lumens. Beam angle indicates the spread of light from the light source. A narrow beam gives a concentrated light which is better for accent lighting. A wide beam gives a more general, softer light.       

Warm white and cool white

The colour temperature measures the colour of light in units known as the Kelvin. Warm light is measured in lower numbers and cool white in higher numbers. Whether you choose warm white or cool white is a personal preference.

Cool white is ideal for task-orientated areas like kitchens and laundries and areas that have a warmer climate, as the lighting will help to make the rooms feel cooler. Warm white creates a more intimate and relaxing atmosphere suited to bedrooms and living rooms. We recommend sticking to just one colour throughout an open plan living area, as the mixing of colours will be distracting to the eye.

Energy saving tip:

  • Use two-way switching in rooms with two exits to ensure lights can easily be turned off when leaving the room.
  • Motion sensors in toilets save energy and are very handy
