GU10 or Integrated -

Which Downlight Suits You?

Integrated LED downlights come as one unit. The fitting is purposly designed around the LED. They are technologically more advanced, with superior thermal management.

GU10 downlights are a combination of two separate components; an LED with a GU10 cap and a GU10 downlight.

GU10 Downlights

Most GU10 fire rated downlights are fully enclosed and don’t offer any ventilation to the LED. Cutting off the air supply to an LED can cause it to overheat and fail.

GU10 downlights are made up from 2 separate items

Integrated LED Downlights

Integrated downlights are more technologically advanced: but if they ever fail, you’ll have to replace the entire fitting.

Integrated downlights are more reliable & have longer guarantees

Colour Temperatures

Traditional light bulbs like halogens had a warmer 2700K colour tone. Known as extra warm white, they’re ideal for use in living rooms, some people think this is too orange. Warm white 3000K is the most popular colour temperature. It produces a mid-range, clearer tone of light than 2700K but not as harsh as 4000K cool white...Just right? The cool white 4000K produces a whiter, cleaner tone of light. Used in the right setting, this can make a room appear modern and bright, but used incorrectly, like in a living room, it can make a room feel cold and sterile.

DimTone LEDs dim in colour temperature as well as brightness

Wiring & Connectivity

Most premium downlights have push-fit terminals. Economy downlights have screw terminals which take more time & effort to terminate the cables.

Push-fit terminals are quick & easy.

Wiring & Connectivity

Plug-in wiring connectors come as standard with most premium quality integrated downlights.

They reduce installation times and make wiring considerably easier. You wire one side of the connector into your lighting circuit during the first-fix phase. Usually with the loop-in, loop-out method. Then plug the downlight in When your ready.

Then connect the downlight into the circuit when you’re ready during the second-fix phase.


Consideration How are you going to control your new lights? .

Basic light switch, dimmer switch or Smart Lighting system perhaps?

A Lightwave Smart switch converts ordinary lights into smart lights. Allowing you to control them with a smartphone. Set scenes, dim, switch and create automated timer functions from the App.

Beam Angles

A wider beam angle doesn’t emit more light, but it does spread the light out further and more evenly.

If you’re illuminating a smaller room like a bathroom for example, a medium beam of 40 degrees is fine. But if you’ve got a larger room such as a living room, a wider 60 degree beam would be a far better choice.

Narrow beams like 25 degrees are more focused and intense. They are better suited for illuminating specific objects or areas and for rooms with higher ceilings.

Fire Rated Downlights Most LED downlights are fire rated as standard these days. If you’re installing downlights in homes, they should be fire raed.

In the event of a fire, a fire rated downlight seals off the hole and delays the spread of fire

Insulation Coverable

Some downlights can be covered directly with thermal insulation, without needing accessories.

Insulation Coverable Some downlights require additional accessories such as Spot Clips or Loft Lids to allow them to be covered with insulation.


Ultimately, many purchasing decisions come down to cost, but consider:

• Lumen output (Brightness) • Efficacy (Lumens per Watt) • Life Expectancy • Guarantee period • Quality of material • Reliability of the brand • GU10 vs Integrated • Type of wiring connector • Insulation cover-able • Shallow ceiling void • Matching existing hole sizes

These are some main of the reasons why some Downlights cost more than others... They are better!
