PlasCity manufactures LED light diffusers used to spread and soften light output evenly across a fixture, made in round, plain, and square profiles to fit different lighting designs.
What is an LED light diffuser
It is an extruded plastic cover fitted over an LED strip or panel that scatters the light passing through it. Instead of seeing individual bright LED points, the output looks like one smooth, even glow across the full fixture length.
Round Diffusers
Curved profile designed for cylindrical or tube-style LED fixtures, giving even light spread around the fixture body.
Plain Diffusers
Flat, uniform profile designed for a simple, even light spread without a shaped or curved surface.
Square Diffusers
Square-edged profile designed for panel-style and linear LED fixtures where a flat-sided housing is needed.
