45W High-Output Edge-Lit LED Bar for Large Light Boxes – 958mm, 4400lm

45W edge-lit LED bar for large-format light boxes

This 958mm high-output LED light bar is built for large SEG fabric lightboxes, commercial backlit graphics and exhibition display walls. It delivers 4400 lm ±10% from a 45W DC24V bar, using a 14°×47° asymmetric lens to project light from the frame perimeter toward the graphic.

Where this high-output lightbox bar is used

• Airport, transit and shopping-center advertising: illuminate large-format fabric graphics in compatible commercial frames.
• Retail and showroom displays: build backlit feature walls, campaign graphics and product-launch backgrounds.
• Trade show and event production: light large SEG booth walls, island exhibits and reusable exhibition frames.
• Automotive, furniture and architectural displays: support large graphics behind vehicles, room sets and material presentations.
• Sign makers and display manufacturers: specify a long, high-output perimeter bar for tested OEM and production layouts.

Why choose the 958mm, 45W format?

A longer, higher-output bar can reduce the number of bars and connection points in a suitable tested frame compared with shorter, lower-output products. It does not guarantee a fixed module count. Frame depth, graphic material, reflective surfaces, spacing, mounting edges and target brightness determine the final layout.

Build and test a sample before production, especially for large graphics where visible hotspots or a dark center would be costly to correct after installation.

Key specifications

Driver and wiring planning

• Size the DC24V constant-voltage driver for the selected pack layout, total connected load and suitable operating margin.
• Confirm the Molex 5557 / Mini-Fit Jr. pinout, mating connector and polarity before power-up.
• Account for cable rating, voltage drop, connection count and installation conditions.
• Disconnect power before installation or service.
• Use the included hand-tighten screws only with a compatible frame and mounting arrangement.

For a production project, send us the frame drawing, graphic size, depth, target brightness, planned bar spacing and driver design before ordering.

What's Included (per light bar)

• 1 x LED light bar
• 2 x plastic mounting accessories

Questions buyers ask

Will one 958mm bar light my whole large lightbox?
Not necessarily. The required number depends on frame depth, graphic dimensions, reflective surfaces, mounting edges and brightness target. Test the optical layout rather than ordering from length alone.

Does the pack include a DC24V driver?
No. Select a compatible constant-voltage driver separately for the total load.

Is the color temperature switchable?
No. Choose one fixed CCT range when ordering.

What does the displayed price cover?
It covers the selected 10-pack, 50-pack or 100-pack variant.

Can I use this in a SEG fabric lightbox?
It is designed for compatible SEG and commercial edge-lit frames, but uniformity must be confirmed with the actual frame depth, fabric and reflective interior.
