What Are Acrylic Lighting Diffusers?
Acrylic lighting diffusers are panels fitted over LED, fluorescent, or recessed fixtures to soften and evenly distribute light. They reduce harsh glare, hide LED modules and fittings, and protect the light source from dust and damage. Opal white acrylic delivers maximum diffusion with a clean opaque finish; frosted acrylic offers a semi‑transparent satin look for decorative settings. Both are precision‑cut to your exact L × W × thickness (mm) in our Johannesburg workshop.
Applications — Environments & Benefits
• Retail ceilings & shelving — Even, glare‑free light across product shelves, gondola bays, and promo lightboxes for better visual merchandising.
• Pharmacies & clinics — Soft, uniform illumination for dispensing areas, consultation counters, and patient signage — clean and easy to maintain.
• Corporate & offices — LED troffer covers and ceiling grid panels that reduce eye strain in open‑plan environments and meeting rooms.
• Hospitality — Bar and reception backlighting, menu boards, feature niches, and pendant fittings with a warm, diffused glow.
• Exhibitions & events — Temporary lightboxes, backlit wall panels, and branded feature stands with consistent colour temperature.
• Industrial & warehouse — High‑bay light diffusion and safety glare reduction in work and packing areas.
• Architects & interior designers — Specify custom opal or frosted diffuser panels for feature ceilings, linear slot diffusers, and bespoke lighting installations. We cut to your CAD dimensions.
Specifications & Options
Available materials
• Opal white acrylic — High light diffusion, opaque white finish. Best for office troffers, ceiling grids, and lightboxes requiring maximum diffusion. Typical thickness: 2–4 mm.

• Premium grades available: Perspex® and PLEXIGLAS® opal or frosted on request.
Sheet sizes & tolerances
• Standard sheet: up to 2050 × 3050 mm — cut to your custom dimensions.

• Corner radii, clip slots, and cut‑outs available to match existing housings.
Usage notes
• Indoor use standard. Covered‑outdoor (patio, canopy) possible with UV‑stable grades.
• UV‑stable acrylic resists yellowing indoors. Specify environment when quoting.

FAQs
Frequently Asked Questions — Acrylic Lighting Diffusers
1. Can you cut diffusers to my exact size?
Yes — send length, width, and thickness in millimetres (L × W × T), plus quantity. We precision‑cut to ±0.5 mm to fit standard LED troffers, ceiling grids, and custom fixtures.
2. What is the difference between opal and frosted acrylic?
Opal white gives maximum light diffusion with a clean opaque finish — best for office troffers and lightboxes. Frosted is semi‑transparent with a satin appearance, ideal for feature panels where some light transmission is desired.
3. What thickness do I need?
Most ceiling and troffer applications use 2 mm, 3 mm, or 4 mm. We'll confirm the best option when you share your fixture details. Heavier or custom thicknesses can be quoted on request.
4. Can I match diffuser panels across multiple stores or branches?
Yes — we batch‑cut orders from the same material lot and keep your spec on file. Repeat orders are produced to the same dimensions, thickness, and finish, ensuring consistency across all sites.
5. What are your typical lead times? Can you rush?
Standard turnaround is 7–10 business days from spec confirmation. Rush orders can be arranged — let us know your deadline when you send your brief.
6. How are panels packed and shipped SA‑wide?
Each panel is interleaved with protective film, edge‑protected, and packed flat in sturdy cardboard or plywood crates. We courier nationwide from Johannesburg. Delivery cost is quoted upfront with your invoice.
7. Is acrylic UV resistant? Will it yellow over time?
General‑purpose acrylic is UV‑stable and resists yellowing indoors. For outdoor or high‑UV exposure, we can supply UV‑stabilised grades — specify your environment when requesting a quote.
8. What fire rating options are available?
Standard acrylic is combustible. If your project requires a specific fire classification, advise us and we will source an appropriate grade. Always confirm requirements with your project fire engineer.
9. Will your panels fit my existing light fittings?
Yes — we cut to your exact L × W dimensions and can accommodate corner radii, clip slots, and cut‑outs to match your housing. Send a photo or drawing and we'll match it precisely.
10. Can diffusers be installed in covered outdoor areas?
Diffusers are primarily designed for indoor use. Covered‑outdoor applications (under a patio or canopy) are possible with UV‑stable grades and proper enclosure. Discuss your project with our team.
11. Is there a minimum order quantity?
No minimum — we make single replacement panels and large bulk orders alike. Trade and bulk rollouts receive priority scheduling and competitive pricing.
