What is the light transmittance of a Tri Proof Lamp Cover?

Sep 02, 2025

Hey there! As a supplier of Tri Proof Lamp Covers, I often get asked about the light transmittance of these covers. So, I thought I'd write this blog to clear up any confusion and give you all the info you need.

First off, let's talk about what light transmittance actually means. In simple terms, light transmittance is the measure of how much light can pass through a material. For a Tri Proof Lamp Cover, this is super important because the whole point of the cover is to protect the lamp while still allowing as much light as possible to shine through.

The light transmittance of a Tri Proof Lamp Cover can vary depending on a few factors. One of the main factors is the material used to make the cover. Most Tri Proof Lamp Covers are made from plastic, which is a great choice because it's lightweight, durable, and can be easily molded into different shapes. There are different types of plastics used, such as polycarbonate and acrylic.

Polycarbonate is a popular choice for Tri Proof Lamp Covers. It has excellent impact resistance, which is crucial for a cover that needs to protect the lamp from physical damage. In terms of light transmittance, polycarbonate can have a transmittance rate of around 85 - 90%. This means that 85 - 90% of the light produced by the lamp can pass through the cover. That's a pretty high percentage, which is great for ensuring that the light from the lamp can effectively illuminate the area.

Acrylic, on the other hand, is also a common material. It's known for its high clarity and good light transmittance. Acrylic Tri Proof Lamp Covers can have a light transmittance rate of up to 92 - 93%. This makes acrylic a great option if you're looking for a cover that allows almost all of the light to pass through. However, acrylic may not be as impact - resistant as polycarbonate, so it might not be the best choice in environments where the lamp is likely to be exposed to a lot of physical stress.

Another factor that can affect light transmittance is the thickness of the cover. Generally, the thicker the cover, the lower the light transmittance. This is because the light has to travel through more material, and some of it gets absorbed or scattered along the way. So, when choosing a Tri Proof Lamp Cover, you need to find a balance between the thickness required for protection and the need for high light transmittance.

The surface finish of the cover also plays a role. A smooth surface finish allows light to pass through more easily compared to a rough or textured surface. Textured surfaces can scatter the light, reducing the overall light transmittance. However, in some cases, a textured surface might be desirable for other reasons, such as diffusing the light to create a more even illumination.

Now, why is light transmittance so important for Tri Proof Lamp Covers? Well, if the light transmittance is too low, the lamp won't be able to effectively light up the area. This can be a big problem in places like warehouses, factories, or parking lots where good lighting is essential for safety and productivity. For example, in a warehouse, workers need to be able to clearly see the products on the shelves and navigate the aisles. If the light from the Tri Proof lamps is being blocked by a cover with low light transmittance, it can increase the risk of accidents and make it harder to get the job done.
