Grafix Opaque Craft Plastic – Opaque .010” Craft Plastic Film
Grafix Opaque Craft Plastic provides a sturdy, flexible surface ideal for DIY crafts, mixed media, and stamp work. The .010” thickness makes it easy to cut with common tools, while the surface is acid-free and archival-friendly, helping preserve artwork over time. It is suitable for watercolors and fluid art applications where opacity helps block underlying layers, creating cleaner color separation. The combination of durability and ease-of-cutting supports a wide range of craft and display projects where a non-reflective, opaque finish is desired.
Gel Light Filter – 14 Pieces Colored Overlays
These colored PVC light filters transform standard LED lighting by adding festive or ambient color without sacrificing light diffusion. Each sheet is designed to be lightweight yet sturdy, with a protective film on both sides for shipping protection. They can be cut to fit non-standard shapes and are commonly used to alter color temperature or to create decorative lighting effects for landscape lighting, stage setups, or holiday displays. The set offers consistent color quality across sheets, making it a practical choice for designers exploring color-mixed lighting schemes.
Sibe-R-Plastics Black Opaque Acrylic Sheet 1/4”
This thick black opaque acrylic sheet offers strong weather resistance and low water absorption, making it suitable for exterior signage, displays, and protective panels. It is thermoformable, which supports shaping for custom lighting fixtures or light-diffusing panels. At 1/4” thickness, it provides robust rigidity for large-format signs and opaque light-shielding components while maintaining a relatively light profile compared with glass.
Sibe-R-Plastics White Opaque Acrylic Sheet 1/8”
This white opaque acrylic sheet provides a clean, non-translucent surface suitable for signage, displays, and light-diffusing panels. It shares the same standout properties as other Sibe-R-Plastic products, including weather resistance and low water absorption, while remaining thermoformable for curved or custom shapes. The 1/8” thickness offers a balance between rigidity and light diffusion, making it a flexible option for crafting opaque lighting enclosures and protective covers.
BuyPlastic Polycarbonate Sheet – Black 1/4”
This polycarbonate sheet provides high impact resistance and UV stability, making it an excellent opaque substitute for glass in lighting enclosures and outdoor installations. The nominal 1/4” thickness delivers enhanced strength while remaining lighter than glass. Its opaque black finish helps block light in undesired directions, enabling more controlled diffusion and glare reduction in lighting fixtures and display cases. It is suitable for durable shields, compact lighting housings, and signage that require robust performance.
Xadnitu Recessed Lighting Half Shades
These opaque recessed light covers soften harsh glare from can lights, providing a more comfortable brightness balance in living spaces. Made of anti-yellow plastic with lightweight, waterproof, and heat-resistant properties, they offer a long service life and simple installation. The white finish aligns with modern and minimalist decors, and the half-shade design helps diffuse light while maintaining a clean, unobtrusive look for ceilings and lighting fixtures.
Cast Acrylic Plexiglass Sheet – White 3/16”
Cast acrylic (PMMA) offers scratch resistance and durable opacity, suitable for signs, containers, and barrier panels. The sheet is white and opaque, with a thickness of 3/16”, providing a sturdy, light-diffusing surface for custom lighting enclosures, display frames, and protective panels. It balances optical clarity with opacity to minimize unwanted light bleed while maintaining strong impact resistance for everyday use.
Kichler ILS TE Series Tape Lens
The opaque white tape lens focuses and shapes light output for specific fixtures, enabling a clean, controlled diffusion pattern. This component is designed to fit within certain Kichler lighting systems, providing easy integration with compatible housings and lens configurations. Its opaque finish helps to minimize stray light and create a sharper, more cohesive lighting effect in cabinetry, under-cabinet, or display lighting setups.
Buying Guide: Key Purchase Considerations
- Opacity vs. diffusion: Higher opacity reduces light bleed but may reduce total output. Choose materials with the right balance for your fixture and aesthetic.
- Durability and environment: Exterior installations require weather resistance and UV stability; interior projects may prioritize weight and flexibility.
- Compatibility and fabrication: Check thickness, thermoformability, and ease of cutting/dying to ensure compatibility with tools and shaping methods you plan to use.
- Color and finish: For decorative lighting, colored overlays offer design flexibility; opaque white or black finishes help with glare control and contrast.
- Cost and availability: Compare sheet sizes, minimum orders, and supplier support to avoid delays in project timelines.
- Safety and standards: For lighting enclosures, ensure materials are flame-retardant or meet relevant regulations if used in occupied spaces.
When selecting opaque plastics for lighting, consider how the material will diffuse or block light, the environmental exposure, and the fabrication methods you’re comfortable with. Combining materials—from craft plastics to high-strength polycarbonates—can help meet both aesthetic goals and structural requirements for lighting projects and crafts.
