LED diffuser comparison test for SL7 profile

LED diffuser comparison test for SL7 profile

It is a question that we are asked over and over again: "What is the difference between the different diffusers for this LED profile?"

Each diffuser type has different aesthetics both when the LED strip is illuminated and when is it off. In this test, we used our in-house scientific light measurement tools to measure the the light transmission of the diffusers for our SL7 surface mount LED profile.

For purposes of this test, we used the 120 LEDs/m version of our White Iris Series High CRI LED strip in Warm White (3000K).
