Acrylic material is widely used in lighting because clear PMMA can reach about 92% light transmission under ASTM D1003 testing. For LED diffuser applications, the formula is adjusted to balance transmission and haze, so the sheet can hide LED dots while keeping enough brightness.

PMMA Vs PC Diffuser Sheet is a common material decision in lighting projects. Both materials can be used for LED panel lights, ceiling lamps and commercial lighting fixtures, but their performance focus is different. Choosing the right sheet affects brightness, glare control, impact resistance, processing stability and long-term maintenance cost.

PMMA is widely used in LED diffuser sheets because standard clear acrylic can reach about 92% light transmission under ASTM D1003 testing. For diffuser applications, transmission is usually adjusted to around 80%–92% depending on lamp structure. Higher transmission supports brightness, while higher haze helps cover LED dots and improve visual comfort.
