FAQ: LED Light Diffuser Solutions

Everything you need to know about selecting the right optical polycarbonate sheets.

Q: Is Polycarbonate better than Acrylic (PMMA) for LED diffusion?

A: Yes, for most industrial and commercial applications. While Acrylic has slightly higher clarity, Polycarbonate (PC) offers far superior heat resistance (up to 120°C) and is virtually unbreakable (250x stronger than glass). This makes PC the safer choice for high-power LED fixtures and public environments.

Q: How do I choose the right light transmission rate?

A: It depends on the distance between the LEDs and the diffuser. For slim profiles, a lower transmission (60-70%) is better to hide hotspots. For deep fixtures, higher transmission (80-90%) can be used to maximize brightness while maintaining a uniform "line of light."

Q: Do you provide custom cut-to-size and CNC services?

A: Absolutely. We provide professional CNC routing and laser cutting services. Whether you need circular discs for downlights or complex shapes for architectural fixtures, we can provide precision-cut pieces based on your CAD drawings.

Q: Are your LED diffuser sheets fire-rated?

A: Yes. Our optical grade polycarbonate is available with UL94 V-0 or V-2 fire ratings. This is a critical requirement for safety compliance in commercial buildings, airports, and industrial facilities.
