When choosing the right lighting for outdoor projects, the lamp shade material can make all the difference. Two of the most common materials — plastic and acrylic (PMMA) — may look similar at first glance, but they perform very differently when exposed to sunlight, rain, and temperature changes.
So, what’s the difference between the two? And which one should you choose for outdoor use? Let’s take a closer look.
💡 Material Comparison: Plastic vs Acrylic
1. Composition
Plastic lamp shades are typically made from PP, PE, or PS — general-purpose plastics that are lightweight and cost-effective. Acrylic shades, on the other hand, are made from PMMA (polymethyl methacrylate), known for its glass-like clarity and superior durability.
2. Light Transmission
Plastic shades usually have a light transmittance below 80%, while acrylic can reach up to 92%, offering a brighter and clearer glow — almost as transparent as glass.
3. UV and Weather Resistance
Ordinary plastic tends to yellow or become brittle under sunlight, while acrylic has excellent UV resistance, maintaining its color and appearance even after years outdoors.
4. Impact and Temperature Resistance
Acrylic is more impact-resistant (10 times stronger than glass) and performs well in both hot and cold climates. Plastic, however, may deform or crack when exposed to extreme weather.
5. Weight and Cost
Plastic is lighter and cheaper, making it ideal for budget projects or temporary installations. Acrylic is slightly heavier and more expensive, but it provides long-term stability and superior aesthetics.
☀️ Which Is Better for Outdoor Use?
✅ Acrylic lamp shades are the clear winner for outdoor lighting.
Here’s why:
• They resist UV aging, staying bright and crack-free even under strong sunlight.
• Their weatherproof durability suits both hot and freezing environments.
• They provide high light clarity, creating a softer, more appealing glow.
• They have a longer lifespan, reducing replacement and maintenance costs.
In contrast, plastic shades are more suitable for indoor or short-term decorations, such as party lights or trade show displays.
🏭 Application Suggestions for Importers and Buyers
• Outdoor Commercial Lighting (street lamps, garden lights, festive displays):
→ Go with acrylic shades for reliability and longevity.
• Indoor or Temporary Lighting (event lights, exhibition displays):
→ Choose plastic shades for a cost-effective solution.
✨ Final Thoughts
When quality and durability matter, acrylic is the smarter investment for professional outdoor lighting.
It not only enhances visual appeal but also saves time and maintenance costs in the long run — a crucial factor for distributors, retailers, and large-scale lighting projects.
