Lightbox Brightness: How Many Nits Is Enough?

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.

Indoor Retail

Standard indoor SEG lightboxes should hit 800–1200 nits on the fabric surface. Anything dimmer looks gray next to bright store lights. Anything brighter is overkill.

Window and Outdoor

Window displays facing daylight need 3000–5000 nits to beat ambient sunlight. True outdoor pylon signs need 5000+ nits and IP65-rated LED drivers.

Measuring It

Use a cheap light meter app on your phone held against the fabric. If it reads under 800, add more LED strips or switch to brighter 3030 SMD chips.
