There are different kinds of diffusers(cover) for aluminum LED profiles. The diffuser can protect the led strip and make the surface cleanable, different designs of diffuser give the lighting a different look and light output.
00:36 Transparent(Clear) diffuser. 95% transmittance rate. the brightness of led strip have almost no loss. However, the led strip is visible under the diffuser, these diffusers are mostly used for kitchen counter lighting, shelf and showcase lighting. Where we can’t see the led profile, and the light is not disturbing.
01:03 Frosted (semi-transparent) diffuser. 85% transmittance rate, the decrease in brightness is not very large. However, the led strip is mainly covered, and they reduce hotspots significantly.
01:32 Opal diffuser. 80% transmittance rate. It’s sort of opal white coating that helps diffuse the light evenly. And can maximizes hotspots.It’s decorative when switched off, as we don’t see into the profile, the led strip is not visible.
01:58 Milky diffuser, 70% transmittance rate. A milky diffuser is more opaque than opal diffuser and eliminates hotspots. you may install brighter led strip to increase the brightness.
02:22 Black diffuser, 60% transmittance rate. it completely hides the light sources, so the LED channel looks like one single LED channel track. It’s also decorative when switched off, just like a circle of black lines.
02:45 Silicone diffuser: 70% transmittance rate. It’s soft and flexible, allows you to mount it on some curved or ring circular led profiles.
03:38 Lens diffuser: it’s an optical lens design of transparent diffuser. Which narrow the 120-degree beam angle of the led strips, to 10 degrees, 30 degrees and 60 degrees. So it will light a smaller surface, in exchange for higher brightness there.
