Frequently Asked Questions

Q: Does this listing include the LED strip or aluminum profile channel?

A: No — this listing is for the silicone diffuser cover only. The LED strip lights and aluminum profile channel are sold separately. Please ensure your aluminum channel is a U-type or T-tube profile compatible with the width you select.

Q: How do I choose the right width for my aluminum LED channel?

A: Measure the inner opening width of your aluminum profile channel carefully. Available widths are 9mm, 10mm, 12mm, 15mm, 20mm, 25mm, and 28mm. If you are unsure, order a 0.2m sample set to check the fit before purchasing a full-length roll.

Q: What is the difference between Milky White (Type A/B) and Pure White (Type C)?

A: Milky White diffusers soften and scatter the LED light more, creating a gentle, uniform glow that hides individual LED dots. Pure White diffusers are more translucent and allow slightly more light through while still providing a clean, polished finish.

Q: Is this silicone diffuser heat-resistant and safe for long-term indoor use?

A: Yes. The diffuser is made from flexible, heat-resistant silicone, making it suitable for long-term indoor lighting use with standard 12V DC LED strip systems. The product holds CCC, CE, FCC, and RoHS certifications for your peace of mind.
