PRODUCT OVERVIEW
Fluorescent Tube Diffuser Soft, even, glare-free light from every tube
What is a tube diffuser? A fluorescent tube diffuser is an extruded plastic cover that fits over or around a tube light. It spreads the light, hides the bright tube and shields it from dust and knocks. The same covers work with LED retrofit tubes in standard fixtures.

Light is emitted
Diffuser scatters it
Soft, even light
The tube sends out bright, direct light that can dazzle and create hot spots.
Additives and surface texture in the plastic scatter rays in many directions.
Glare drops and brightness spreads smoothly across the room.
Result: soft, even light with no visible hot spots xtruline.com
