Why CRI Matters for Lightbox LED Strips

Frequently Asked Questions

Q: How do I choose the right solution for my project?
Start by defining your budget, installation environment (indoor vs outdoor), and how long you expect the display to last. If you are unsure, send us your drawings and dimensions, and our engineers will recommend the best option within 24 hours.

Q: What is the minimum order quantity?
Standard items have no MOQ. Custom colors, custom sizes, and private label packaging usually require 500–1000 pieces depending on the product. Sample orders are always welcome before bulk production.

Q: How long is the lead time?
Standard stock items ship within 3–5 working days. Custom production takes 15–25 days depending on quantity and tooling. We can also rush orders for urgent trade shows if needed.

Q: Do you ship worldwide?
Yes. We export to 40+ countries including the USA, Germany, UK, Australia, and the Middle East. We can ship by sea (FCL/LCL), air, or express courier. We handle export documentation, customs declaration, and commercial invoice preparation.

Practical Tips Before You Order

Before placing an order, always confirm three things: first, double-check your exact dimensions and corner angles against your space. Second, ask for a physical sample before mass production—what looks good on screen may feel different in person. Third, plan for spare parts (LED strips, drivers, edge strips) at the same time as your main order, because reordering small spare parts later usually costs more than the parts themselves.

For long-term projects, we recommend keeping a detailed spec sheet for every installation: what size frame, what color strip, what LED color temperature, and which driver version. This makes future replacements and maintenance much faster. EEYUN has been manufacturing SEG lightboxes, aluminum profiles, and LED strips in Hangzhou, China since 2010, and we support OEM/ODM for distributors and brand owners worldwide.

What Is CRI?

CRI (Color Rendering Index) measures how accurately a light source reveals true colors compared to natural daylight. CRI 100 is perfect. Most lightbox LEDs are CRI 80; premium retail displays specify CRI 90+

Why It Matters for Printed Fabric

A brand red printed on SEG fabric will look orange under CRI 70 LEDs and true red under CRI 95. If you are printing branded graphics for retail chains, CRI 90+ is worth the 10–15% premium.

Practical Specification

For general advertising lightboxes, CRI 80 is fine. For high-end retail, art galleries, and brand flagship stores, specify CRI 90 minimum. Always request a CRI test report from your LED supplier.
