How to choose the right downlights? Insider Tips

Factors & Choices

Here we only list some of the most important factors we have to consider before we can make a correct decision:

FactorsYour choices
1AS/NZS Certificate/ Test Report

Never use any downlight which has not been approved to meet AS/NZS standards 60598.2.2. You must check carefully if the SDoC provided by your supplier shows that the light meets AS/NZS standards. A test report number or SAA number should be provided in the SDoC.

Att: CE certificates are not for AS/NZS standards and Chinese CCC certified lights are not allowed to be sold in NZ without further tests.

2Cut-out sizeFor an LED light replacement project, you have to measure the size of the old holes on the ceiling. Most old holes are around 90mm in diameter. But you still need to double check it before purchasing.
3Light colour

Three common options: 3000k warm white, 4000k cool white and 6000k daylight.

Here is the government recommendation but it totally depends on your favor: A ’warm white’ colour will be suitable for lounges, hallways and bedrooms and a ‘cool white’ colour will be suitable for laundries, bathrooms and offices.

4LumensFor a residential use, we often choose a downlight which can produce 700 - 1000 lumens.
5Wet or dry area?For bathroom use, the minimum requirement is IP44 rated, same as the lights used in soffits. IP55 or IP65 are recommended for any area where water will be directly sprayed. Our 10W and 13W downlights are all IP44 rated.
6Safe?One of the most important advantages of LED downlights is that LED lights don't product as much heat as other lighting sources. But not all LED downlights are safe to be covered by insulation materials. Try to choose LED downlights which are IC or IC-F rated. They are safe to be covered by insulation that can safely be exposed continuously to temperatures up to 90°C. Click here for more details about the ratings.
7Beam angleIt depends on your application. 35 degree beam angle lights can provide you a perfect spot light effect. If you want your living room evenly covered, choose lights with 90 degree or more beam angles. Recessed downlights are much more popularly used in NZ than non-recessed ones.
8QualityGenerally speaking, the heavier the light, the better quality. Aluminum housing lights can normally last longer than the plastic ones. A heavy
9Flicker-freeLED lights can be flicker-free or with flickers. Only LED lights with DC converters are almost completely flicker-free. Flicker-free lights can protect your eyesight but obviously they will cost you a little bit more. You can easily tell if it is flicker-free by simply using the camera of your smart phone.
10Dimmable?If you have and want to use a dimmer, you need to buy dimmable LED downlights. The price of dimmable LED downlights are normally 20% higher than non-dimmables. Most dimmable downlights which meet nz standards are compatible to our existing dimmers. Our 10W and 13W downlights are all dimmable.
