Clear vs. Milky – which one should you choose?
Both transparent and milky/opal silicone sleeves serve different purposes. Here's how to choose the right one for your lighting project.
| Feature | Transparent Sleeve | Milky/Opal Sleeve |
|---|---|---|
| Light effect | Bright, direct light – individual LEDs visible | Soft, uniform glow – no visible LED dots |
| Light transmittance | >92% | 65–75% |
| Best for | Functional lighting, color-critical applications | Ambient lighting, decorative applications |
| Visual effect | 'See the light source' | 'See the light, not the source' |
| Color accuracy | Excellent – pure color reproduction | Good – some color softening |
💡 Choose transparent for bright, crisp light with pure color rendering. Choose milky/opal for soft, uniform illumination without visible LED dots.
