Why Choose Edge-lit LED Light Bar for Light Boxes?
High Brightness for Advertising Displays
High brightness LED edge light bars provide strong luminous output for advertising light boxes, retail signs and commercial displays. The 6500K cool white light creates a clean and bright visual effect, helping graphics and signage stand out clearly.
Uniform Illumination for Double-sided Light Boxes
The edge-lit design helps distribute light across the panel surface, making it suitable for double-sided light boxes and large-format illuminated displays. Proper installation distance and light bar quantity help reduce dark areas and improve uniformity.
Efficient Heat Dissipation
The aluminum PCB and aluminum profile support better heat dissipation. Good thermal management is important for maintaining brightness, protecting LED chips and extending the working life of the light bar.
Safe DC24V Operation
The DC24V input voltage is safer and widely used in commercial LED lighting systems. The DC24–30V wide voltage range helps maintain stable brightness and supports different light box installation conditions.
Applications of High Brightness LED Light Bar
Double-sided advertising light boxes
Retail display light boxes
Outdoor and indoor illuminated signage
Commercial brand display panels
Shopping mall advertising displays
Airport, subway and public advertising light boxes
Large-format edge-lit display systems
How to Choose LED Edge Light Bar Quantity
The required quantity of LED edge light bars depends on light box depth, length, width, single-sided or double-sided lighting, brightness target and installation structure. For example, if the light box is 115 × 250 cm, lights may only need to be installed along the 115 cm sides, depending on the internal light transmission distance and brightness requirement.
If buyers provide light box dimensions and frame pictures, Wallis can recommend the correct model, quantity and installation method to reduce dark areas and control lighting cost.

Frequently Asked Questions
Can the LED edge light bar be cut?
It is not recommended to cut this aluminum PCB light bar with ordinary tools because the aluminum PCB is 2 mm thick. If cutting is needed, buyers should inform Wallis in advance so the light bar can be professionally cut and soldered with terminal connectors before delivery.
Why are there two LED light bars with the same appearance but different lengths?
The available light bar lengths include 47 cm and 20 cm. The 20 cm light bar is designed for shorter distances where a 47 cm bar cannot fit, helping avoid dark areas at the end of the light box and improving brightness uniformity.
What information should I provide to confirm whether it is suitable for my project?
Please provide the light box depth, length, width, single-sided or double-sided lighting requirement, waterproof requirement, dimming requirement, frame pictures and the number of light boxes. This information helps Wallis recommend the correct LED edge light bar model and quantity.
How do I know the LED edge light bar quantity I need?
The quantity depends on the light box size and lighting direction. For some large light boxes, installing light bars only along two opposite sides may be enough. If you provide the light box size, Wallis can calculate the correct quantity directly.
Is this LED light bar suitable for double-sided light boxes?
Yes. This high brightness edge-lit LED light bar is suitable for double-sided light boxes with enough internal depth, especially light boxes with a thickness of at least 80 mm.
Can Wallis help cut and solder connectors before shipment?
Yes. Wallis can cut the light bar with professional tools and solder terminal connectors before delivery. This helps avoid cutting errors, tool damage and installation problems on the buyer’s side.
