How to Choose High-Quality LED DownLights: NO.1 Materials

Choosing the material for LED downlights can be quite a professional task.

After testing numerous downlights, I found the distinct along different materials .

Let's start with the common materials of LED downlights/LED spotlight, which usually include plastic, plastic-coated aluminum, and pure aluminum.

Pure aluminum can be further divided into die-cast aluminum, profile aluminum, and cold-forged aluminum.

Generally speaking, plastic is often used for the body of regular downlights. It weighs very light and highly malleable. However, it has poor heat dissipation, which can lead to light decay and shorten the lifespan of the light fixture.

Plastic-coated aluminum or die-cast aluminum, on the other hand, have better heat dissipation and are more substantial, providing a higher-quality feel.

Most of the high configuration downlights & spotlights are made of profile aluminum and cold-forged aluminum body, which has sufficient starting weight and higher texture

Meanwhile, profile aluminum and cold-forged aluminum, which are made of abundant aluminium materials, are very substantial and offer a premium feel.

Why is heat dissipation important? This is the biggest difference between different materials for light fixtures. Heat dissipation can be considered the lifespan killer of LED lights. Poor heat dissipation results in more noticeable light decay and faster brightness attenuation.

The so-called light decay exists in all light sources, but the degree of decay varies among different sources. The worse the heat dissipation, the more pronounced the light decay. Therefore, the choice of light fixture is indeed crucial. Apart from the different feel and quality, it also affects the lifespan.

Furthermore, due to poor heat dissipation, plastic components may soften or melt under high temperatures.

If the budget allows, it is advisable to prioritize light fixtures made of thick and solid cold-forged aluminum or profile aluminum, followed by die-cast aluminum.
