LED downlight spacing guide

When it comes to choosing the right size for your space, the most important factor to consider is the spacing between the downlights.

They are available in a variety of sizes, but the most popular size is the 90mm downlight.

The spacing between these downlights should be no more than 90mm apart. This will ensure that the light is evenly distributed and there are no dark spots in your space.

If you have a larger space, you may want to consider downlights with a 100mm spacing. Such downlights with a 100mm spacing will provide more light and coverage than those with a 90mm spacing.

Rule of Thumb spacing method:

The rule of thumb is a general guideline that can be useful when considering how to space your LED light fitting.

However, it is important to use caution when relying on this rule, as there are a number of factors that should be taken into account when determining the ideal spacing for your particular situation.

These factors include the wattage of the bulbs, the size of the room, the purpose of the lighting, and the overall décor. By taking all of these factors into consideration, you can ensure that your LED lighting is installed in an effective and attractive manner.

Spacing criteria method:

The spacing criteria value is determined by the following properties: 

➡The number of LEDs in the fixture

➡The beam angle of the LED 

➡The lumen output of the LED 

➡The reflector type used in the optical design 

➡The spacing between the LEDs 

Depending on these values, you will have to space your LEDs a certain distance apart. As a general rule of thumb, the lower the spacing criteria value, the further apart you will have to space your lights.

For example, if you are using 50 watt LEDs with a beam angle of 60 degrees and a spacing criteria value of 1.2, you will need to space your LEDs 1.2 feet apart.

Is a dimmer recommended for a 90mm downlight?

For a 90mm downlight, a dimmer is not necessary but it is recommended. A dimmer will allow you to control the amount of light that is emitted from the downlight. This can be helpful if you want to create a specific ambience in your space.

How many LED downlights do I need?

The number of downlights you need will depend on the size of your space and the amount of light you want to emit. For a small space, you may only need two or three downlights. For a large space, you may need four or more downlights.

How do I install 90mm LED downlights?
