What are Downlights?
Downlights are one of extremely popular lighting fixtures you can see in any modern home or public commercial space. They provide warm general lighting that's unobtrusive compared to a traditional light fixture. Quality downlights not only provide a clean and minimalistic look, but also they are energy efficient and last longer than ordinary bulbs.

Why choose LED downlights?
I think the major reason is for its super energy saving. You want your downlights to be energy saving yet still produce a high beam. For this reason, we encourage you to use LED downlights. The average 10W LED downlight can produce a beam twice as bright as halogen that use up to 55W. The best option in terms of energy saving can range from as low as 4.5 watts to 14 watts in LED.

How to choose colour temperature?
As a general guide, when choosing LED downlights for a room that tends to get hot such as a kitchen or laundry, cool white is ideal. However, if you want warmth and intimacy in your space like a living room or bedroom, warmer downlights are a better option than their cool white counterpart.
We recommend a natural white 4000K as a good all-rounder. It's cool, clean and feels warm but doesn't overpower your eyes - it's like you have natural skylight coming through the ceiling.

What are Lumens for LED Downlights?
For traditional bulbs and  halogen lights, you need to look at the watts on a light bulbs packaging and determine the brightness of the light. But for LED Downlights the wattage is generally always low because of the energy saving technology. As a result, we now use lumens (lm) to understand the brightness of the LED downlights. Lumens measure the total amount of visible LED downlight from a bulb. The higher the lumens the brighter the LEDdown light.

A important factor for choosing a downlight - Energy Efficiency ( Lumens Per Watts)
When choosing downlights the LED option is a balance between efficiency (watts) and brightness (lumens). For example, if you usually use a 60-watt incandescent bulb, you now probably want to choose a LED downlight that uses 8 to 12 watts and has a lumen rating of 800 for the same amount of illumination.

How to choose recessed downlight beam angle?The beam angle is the amount of light that spreads from the downlight and can be measured in degrees. Most have a beam angle of 45° because they are recessed. By contrast, a regular light bulb would have a 360° beam angle.

Because they are recessed, we recommend selecting downlights with a wider beam (of 60°) if you want soft diffuse lighting in the living room. If you are looking at downlights for the kitchen, however, a narrower beam (of 25°) angle is preferable because it will give you a concentrated light, perfect for when you need to illuminate surfaces and focus on smaller details within the room.

What is Colour Rendering Index (CRI)?CRI means the light source's ability to reveal the colour of objects faithfully in comparison with natural sunlight. The index is measured from 0-100, with a perfect 100 indicating that colours under light appear the same as they would under natural sunlight. Generally, a CRI of 80 - 90 will be within the range of accurate colour rendering.

If prefer to have your lights rendering beautiful, vibrant tones across the full-colour spectrum we recommend a high CRI (90+) in combination with a colour temperature that's middle of the range (4000K).

Lifespans of led downlightsUsually, halogen lights last for 2,000 hours on average. Many people find that they replace the majority of their halogen globes within a 12-18 month period.

For LED downlights, the lifespan is 50,000 hours, which is around 27 years if it's switched on 5 hours a day. As you can see these are far more cost-effective in the long run.

How to install a led downlight?
