27.5W Optical Lens Edge-Lit LED Bar for Light Boxes – 710mm, 3300lm

Precision Optical Beam Control for Light Box Illumination

Featuring a 14° × 47° optical lens design, this LED light bar directs light precisely into the display area — improving light utilization and reducing wasted output. Engineered for professional light box manufacturers, sign makers, and exhibition display builders who require predictable, efficient edge-lighting performance.

The result: brighter, more uniform edge illumination with less wasted light — the engineering-driven solution for commercial light box applications.

Why Optical Lens Matters in LED Light Box Lighting

Why Display Professionals Choose This Light Bar

14° × 47° Precision Optical Lens — Controlled Beam for Better Light Utilization

Unlike standard LED bars that spread light randomly in all directions, this product uses an integrated optical lens to control beam direction. The 14° × 47° asymmetric beam angle focuses illumination within the light box area, improving brightness efficiency and reducing unnecessary light loss outside the display surface. More usable light per watt — engineered for rectangular display frames.

• 14° (narrow axis) — controls depth penetration, directing light across the full depth of the frame toward the display surface
• 47° (wide axis) — spreads light evenly along the frame edge for consistent side-to-side coverage

High Output — 3300lm from 27.5W

At 3300 lumens from just 27.5W, this bar delivers exceptional luminous efficacy. For manufacturers building slim or large-format light boxes, the high lumen output means fewer bars needed per frame — reducing component count and installation complexity without sacrificing brightness.

Wide Color Temperature Range — 2800K to 16000K

With selectable fixed color-temperature ranges from 2800K to 16000K, this light bar accommodates virtually any display application — from warm retail signage to cool-white exhibition backdrops. One SKU covers the full spectrum, simplifying procurement for display manufacturers managing multiple project types.

Aluminum Substrate — Superior Heat Dissipation & Long Lifespan

The aluminum substrate construction draws heat away from the LEDs efficiently, protecting lumen output over time. Plastic-bodied alternatives trap heat, accelerating depreciation and shortening product life. With aluminum construction, you get consistent brightness across the display’s operational lifetime — reducing maintenance and replacement costs for end users.

Four-Side Frame Mounting for Light Box Illumination

Installed along the four aluminum frame edges, multiple LED bars project light inward to illuminate the entire display surface. The optical lens ensures that light from each edge reaches the center panel evenly — eliminating the dark corners and uneven brightness common in back-mounted strip configurations.

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 to the frame. Designed for fast on-site installation and easy repositioning during light box assembly.

Plug-and-Play Connection — Molex 5557 / Mini-Fit Jr. Connector

Each bar connects 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. Connect multiple bars along each frame edge without any wiring tools or soldering.

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

Frequently Asked Questions

What is an optical lens LED light bar?
An optical lens LED light bar uses specially designed lenses integrated into the LED assembly to control light distribution and direct illumination into the target display area, instead of allowing light to spread randomly in all directions.

Why use optical lenses in light box lighting?
Optical lenses improve light utilization by reducing unnecessary light dispersion outside the display area. The result is more usable light per watt, more consistent brightness across the display surface, and more predictable performance during light box design and assembly.

What does 14° × 47° beam angle mean?
It describes the controlled angle range in two axes. The 14° narrow axis directs light across the depth of the frame toward the display surface. The 47° wide axis spreads light evenly along the frame edge. Together, they match the rectangular geometry of commercial light box displays for efficient, uniform illumination.

Is this the same as an edge lighting bar?
This product is mounted along the frame edges, but its defining feature is the optical beam control lens — not simply edge placement. The lens design is what differentiates it from standard LED bars and determines its efficiency advantage in professional light box applications.
