What Is A Trough Light? The Ideal Lighting Solution for Fascia Signs
A trough light is a highly efficient linear LED lighting system designed to illuminate signage and building exteriors. It offers businesses a reliable way to enhance visibility, attract customers, and strengthen brand presence. Suitable for various outdoor conditions, trough lighting ensures your fascia signs, logos, or promotional messages remain clearly visible day and night.
What Is Trough Lighting?
Trough lighting refers to a specialized form of illumination that uses long, narrow fixtures containing high-performance LEDs. These lights are commonly mounted above or below signage to provide consistent, bright coverage. Benwei's Lwnolight series offers industry-leading brightness and energy efficiency, making it easier for businesses to stand out. A range of mounting brackets is available to secure the light to walls, post signs, or sign trays, ensuring a stable and professional installation.
Design and Functionality
A key feature of trough lights is their durable aluminum housing, which protects internal components such as LED strips and power supplies-like the Meanwell driver used in Lwnolight. This construction ensures reliability and longevity even in harsh weather. The slim and low-profile design allows the fixture to blend discreetly into signage setups. Thanks to architectural-grade powder coating, the lights are resistant to rust and corrosion. Custom powder coating options are available to match brand colors.
Benwei also provides tailored light color options, including:
6000K Cool White
4000K Natural White
3000K Warm White
RGBW Color Changing
Easy Installation with Versatile Brackets
Benwei offers multiple bracket types for flexible and secure mounting:
Quick-Fix Pro Bracket: Adjustable to five different orientations.
Quick-Fix Cladding Bracket: Ideal for large signs and billboards, offering extended projection and stronger mounting support.
Adjustable Length for Various Sign Sizes
Trough lights are highly versatile in size. Standard units can be manufactured from 300 mm to 6100 mm. For larger signage, multiple sections can be connected using middle connectors without compromising the IP rating, ensuring continuous weatherproof performance.
Energy Efficiency and Cost Savings
Trough lights with LED technology provide significant energy savings-especially important as energy costs rise. Key benefits include:
Much lower energy consumption than halogen or incandescent lighting
Extended lifespan (up to 30 times longer than traditional bulbs)
Minimal maintenance requirements
These features lead to notable reductions in electricity and upkeep costs over time.
Common Applications
Though originally designed for signage, trough lights are also used for general exterior lighting. Typical applications include:
Billboards
Cut-out letters
Flex face signage
Double-sided signage (e.g., totem signs or pub signage)
Ideal Users

Pubs, restaurants, and takeaways
Hotels and hospitality venues
Retail stores
Schools, hospitals, and offices
