How to choose the cover of LED tube?

The lamp tube made of this cover can see the lamp beads, which is very dazzling and easily dizzy, which does not meet the requirements of human light. The light transmission performance is good, and the light transmission rate can reach 97%. Used to produce high-lumen LED tubes.


      2. Transparent striped cover: This kind of cover is a semi-transparent cover, which can diffuse the light, but the light is not uniform enough and will not dazzle the eyes, and the light transmittance is about 88%.


       3. Diffusion stripe cover: also known as thick stripe cover, the light transmittance of this kind of shell is about 86%, the product made of this shell does not seem to have the feeling of dark area, and the influence of dark area is cleverly avoided.
