1 Select Finish
One of the best ways to choose the right finish is to make sure that your new downlights match other items in the room. Perhaps you've got brushed steel switches, sockets and door handles? Then brushed steel downlights would be a great match.

Polished chrome is popular for bathrooms as it matches taps and other bathroom equipment.

But matt white is our most popular finish as it blends less noticeably into the ceiling.

2 Select Colour Temperature
Most of the LED lights we offer are available in the big 3 colour temperatures which are:

2700K - Extra warm white has a warmer tone, like a halogen, although not quite as orange.

3000K - Warm white is a mid range colour tone. Not as orange as 2700K and not as harsh as 4000K. This is the most popular colour temperature.

4000K - Cool white (or neutral white), although clearer and slightly brighter than the others, it can make a room feel cold and clinical. Used correctly in the right environment it can make a room appear more modern.

If you're unsure about colour temperatures we have colour temperature adjustable downlights available. These downlights contain multiple colour temperatures that can be changed either by a dip switch, wall switch or App. More information about them can be found here.

If you want a brighter light then choose something with more lumens. The brightness difference in colour temperatures is barely 5%.

The Halers H4 Pro 550 SPS from is a single point source adjustable IP65 LED downlight from Collingwood. Using one high output LED chip type it produces a light output ranging from 550 to 560 lumens depending on the selected colour temperature.

Dimmable and fire rated as standard. With a new and improved energy efficiency of just 5W, the H4 Pro 550 SPS is high energy efficient and technologically advanced.
