Hey there! As a supplier of LED plastic covers, I often get asked about the commonly available sizes. Well, in this blog, I'm gonna break it all down for you.
First off, let's talk about the importance of LED plastic covers. They're not just there for looks. These covers protect the LED lights from dust, moisture, and physical damage. They also help to diffuse the light evenly, reducing glare and creating a more comfortable lighting environment. So, having the right size cover is crucial for both the performance and longevity of your LED lights.
One of the most common sizes you'll come across is the T5 tube cover. T5 Tube Cover is designed to fit T5 fluorescent tubes, which are quite popular in commercial and residential lighting applications. T5 tubes typically have a diameter of 5/8 inch (15.875 mm). The corresponding plastic covers are made to snugly fit over these tubes, providing a seamless and protective enclosure. They come in various lengths, usually ranging from 2 feet (609.6 mm) to 8 feet (2438.4 mm), to accommodate different lighting setups. Whether you're lighting up a small office space or a large warehouse, there's a T5 tube cover size that'll work for you.
Another widely used size is the T8 tube plastic cover. T8 Tube Plastic Cover is for T8 fluorescent tubes, which have a larger diameter compared to T5 tubes. T8 tubes have a diameter of 1 inch (25.4 mm). These covers are also available in multiple lengths, similar to the T5 covers. The longer lengths are great for linear lighting installations in corridors, classrooms, and other large areas. The T8 covers are robust and durable, ensuring that your LED lights stay protected for a long time.
In addition to the standard T5 and T8 sizes, there are also other sizes available in the market. For example, there are mini - sized covers for smaller LED bulbs. These are often used in decorative lighting, such as in chandeliers or wall sconces. The diameters of these mini - covers can range from 1/4 inch (6.35 mm) to 1/2 inch (12.7 mm), and they come in cute and compact lengths, usually less than a foot (304.8 mm).
On the other end of the spectrum, there are larger - sized covers for high - bay lighting. High - bay lights are used in industrial buildings, large gymnasiums, and big retail stores. The covers for these lights need to be able to withstand higher temperatures and more demanding environments. The diameters of these covers can be 2 inches (50.8 mm) or more, and they can be several feet long.
When it comes to the manufacturing of these LED plastic covers, Plastic Profile Extrusion Companies play a crucial role. These companies use advanced extrusion techniques to create plastic profiles with precise dimensions. They can customize the sizes of the covers according to specific customer requirements. So, if you have a unique lighting project with non - standard dimensions, you can work with these companies to get the perfect fit.
Now, let's talk about how to choose the right size of LED plastic cover. First, you need to know the diameter and length of your LED tubes or bulbs. Measure these accurately to ensure a proper fit. If the cover is too small, it won't fit over the tube at all. And if it's too large, it'll be loose and may not provide adequate protection.


You also need to consider the application of the lighting. For example, if it's for outdoor use, you might need a more durable and weather - resistant cover. In such cases, you may want to go for a slightly thicker - walled cover, even if it means a slightly larger outer diameter.
Color is another factor. While the size is the main concern, the color of the cover can also affect the lighting output. Clear covers let the most light through, while frosted or tinted covers can create a softer, more diffused light. So, think about the mood and lighting effect you want to achieve when choosing the cover.
