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

High Output Lighting for Large Format Displays

Designed for large commercial light boxes, retail displays, and exhibition backlit walls, this 958mm LED edge-lit bar delivers 4400lm illumination with optimized optical lens distribution. At 45W, it provides the brightness and coverage that large-format applications demand — fewer bars, faster installation, stronger output.

Why High Output Matters for Large Light Boxes

Why Display Professionals Choose This Edge-Lit Bar

45W High Output Performance — 4400lm for Large Displays

With 45W power and up to 4400lm luminous output, this LED edge-lit bar is designed for large-area displays that require strong and stable illumination. Airport advertising panels, retail wall displays, and automotive showroom backdrops demand consistent high-brightness output — this bar delivers it reliably across the full display surface.

Extended 958mm Length for Large Format Applications

At 958mm, this bar is significantly longer than standard 600mm alternatives. The extended length means:

• Fewer lighting bars required per frame
• Faster installation and cleaner internal layout
• Lower component count for large-scale projects

For display manufacturers and exhibition contractors, fewer components means lower labor cost and faster on-site assembly — a direct operational advantage on large-scale projects.

Integrated Optical Lens for Efficient Light Distribution

The 14°×47° optical lens helps direct light into the target display area, improving illumination efficiency for rectangular light box structures. The narrow 14° axis controls depth penetration toward the display surface; the 47° wide axis spreads light evenly along the frame edge for consistent side-to-side coverage.

Professional Commercial Applications

Built for environments where performance cannot be compromised:

• ✓ Large Advertising Light Boxes (airports, transit, retail)
• ✓ Retail Display Walls and Feature Backdrops
• ✓ Exhibition Backlit Booths and Trade Show Display Walls
• ✓ Automotive Showroom Displays
• ✓ Architectural Feature Wall Displays
• ✓ Shopping Mall Lightbox Signage

Tool-Free Mounting — Hand-Tighten Plastic Screws Included

Each light bar ships with transparent hand-tighten plastic screws — no screwdriver required. Simply press and twist to secure the bar onto the aluminum frame of the light box. Designed for fast on-site installation and easy repositioning during light box assembly.

Bar-to-Bar Connection — Molex 5557 / Mini-Fit Jr. Connector

Each bar connects to the next via a Molex 5557 / Mini-Fit Jr. 2-pin connector — the industry-standard locking connector used in professional display and signage installations. Plug in, lock, done. No wiring tools or soldering required.

• Polarity-keyed — no reverse-connection risk
• Secure latch lock — stays connected even with cable movement
• Compatible with standard DC24V LED drivers

Aluminum Substrate — Superior Heat Dissipation

At 45W, thermal management is critical. The aluminum substrate construction draws heat away from the LEDs efficiently, protecting lumen output over time and ensuring consistent brightness across the display's operational lifetime — reducing maintenance and replacement costs for end users.

Frequently Asked Questions

What applications are suitable for high output LED edge-lit bars?
High output LED edge-lit bars are designed for large commercial light boxes, retail displays, exhibition walls and illuminated advertising systems where standard-output bars cannot deliver sufficient brightness across the full display surface.

Why use a longer LED bar for large light boxes?
Longer LED bars reduce the number of lighting units required and simplify installation for large display structures. The 958mm length means fewer bars per frame, lower component count, and faster on-site assembly — a direct cost and labor advantage for display manufacturers and contractors.

How does the optical lens improve lighting efficiency?
The optical lens controls light distribution and directs illumination toward the display area instead of wasting light outside the target zone. The 14°×47° asymmetric beam matches the rectangular geometry of commercial light box frames for efficient, uniform coverage.

What is the difference between this bar and a standard LED edge-lit bar?
This bar is specifically engineered for large-format applications: higher wattage (45W vs 27.5W), higher lumen output (4400lm vs 3300lm), and extended length (958mm vs 710mm). The result is stronger illumination with fewer bars required — optimized for commercial-scale display projects.

How is the light bar mounted inside the light box?
Each bar includes transparent hand-tighten plastic screws. Simply press and twist to secure the bar onto the aluminum frame — no tools required. The bar can be easily repositioned during assembly.

How do the bars connect to each other?
Bars connect via Molex 5557 / Mini-Fit Jr. 2-pin connectors. Plug in and lock — no soldering or wiring tools needed. The polarity-keyed design prevents reverse connection, and the latch lock keeps the connection secure during use.
