Precision-engineered halo-lit and specialty commercial signs for premium brands.
In architectural and retail design, the term "Halo Lighting Signage" (often referred to as reverse-lit or backlit channel letters) represents the peak of three-dimensional brand expression. Unlike face-lit letters that broadcast light forward, halo-illuminated letters project light backward onto the mounting surface. This reflection forms a soft, high-contrast glow—a "halo"—that outlines the letterforms.
To design the perfect halo effect, several optical properties must be managed:
By selecting the correct combination of metals, LEDs, and acrylics, designers can transform standard commercial signage into an architectural feature that enhances visibility, matches local planning regulations, and reduces glare.
A complete system range for business branding, municipal landmarks, and commercial environments.
Kexian is a professional signage manufacturer with over 20 years of experience. Our product range extends from small door plates to large landscape logos and municipal landmarks. All our sign structures are CE, RoHS, and UL certified to meet international standards. We offer OEM and ODM services with low MOQs and fast turnaround times. Partnering with top logistics networks like DHL, UPS, and FedEx, we ensure your signage is shipped safely and arrives on time.
The commercial signage sector has transitioned from simple physical identification to integrated architectural elements. According to industrial construction reports, dynamic exterior architectural lighting directly affects customer traffic and brand recall. As energy costs rise and sustainability initiatives grow (such as LEED certification), businesses are moving away from traditional neon and fluorescent lamps to low-voltage, high-efficiency LED halo signage.
Selecting the right metal alloy is essential for long-term outdoor durability. Under standard atmospheric conditions, Grade 304 Stainless Steel provides excellent corrosion resistance and strength. However, in coastal zones or areas with heavy industrial pollution, saltwater spray and chemical vapors can cause pitting corrosion. For these harsh environments, we recommend and fabricate our signage using Grade 316 Marine-Grade Stainless Steel. Grade 316 contains molybdenum, which significantly improves resistance to chlorides.
The primary cause of LED degradation is trapped heat. High-output LEDs generate internal thermal energy that must be dissipated. Our custom channel letters feature built-in aluminum heat sinks and thermal conductive back-plates. This structure draws heat away from the LED diodes, keeping operating temperatures below 55°C (131°F) to ensure a 50,000+ hour operational lifespan.

Whether you are an architect, corporate developer, or retail shop owner, Kexian is your custom fabrication partner.
A structured, six-stage QA/QC process ensures your sign conforms to design specifications and electrical regulations.
Provide structural drawings, dimensions, font ideas, and your installation environment details. This information helps our engineering team prepare an accurate cost estimate.
Our design team creates 3D CAD visual mockups and structural layouts. We verify letter kerning, stroke thickness, and halo dispersion angles before production starts.
We use fiber lasers to cut metal cases, apply computer-controlled welding for seams, and install UL-certified LED modules with thermal protection.
Each unit undergoes a 24-hour heat-cycle and electrical safety test. We measure illumination levels and inspect structural seals to verify performance before packaging.
Signs are packed in custom wooden crates and shipped globally via DHL, UPS, or FedEx. We manage customs documentation to ensure smooth delivery.
We provide full-size mounting templates, wiring schematics, hardware, and installation videos, backed by a 3-year warranty.

Over 3,000 global installations, from custom business storefronts to large municipal pylon signs.
Kexian has fabricated custom signs for over 3,000 customers globally. We design signs for both indoor and outdoor applications, selecting materials and lighting configurations to match each brand's aesthetic. Our one-stop service has no minimum order quantity, helping businesses of all sizes access custom commercial signage.
Installing illuminated commercial signs requires compliance with local building codes, structural regulations, and electrical safety standards. Failure to meet these criteria can lead to permit denials, municipal fines, or electrical hazards.
All sign structures built for North American markets use components that comply with UL 48 standards for electric signs. This includes UL-listed LEDs, wiring, and enclosures.
Our manufacturing processes adhere to CE and RoHS guidelines, certifying that our products contain no restricted hazardous substances and meet EU health, safety, and environmental criteria.
Our wiring schematics, grounding structures, and disconnect switches are designed to comply with National Electrical Code (NEC) Article 600 requirements for commercial sign installations.
For outdoor pylon signs and high-rise installations, our engineers run structural simulations to ensure the signage can withstand local wind load requirements.
During installation, always verify that your mounting structure can support the weight of the sign. Drywall surfaces may require extra backing studs, while masonry and concrete require suitable expansion anchors.
As cities implement smart infrastructure, illuminated signage is evolving. Sichuan Kexian Advertising is currently developing and testing several next-generation technologies:
Engineering and technical details to help plan your project.
Our typical fabrication lead time is 7 to 10 working days after structural CAD approval and payment. Delivery takes an additional 3 to 7 working days via air shipping (DHL, FedEx, or UPS), depending on your location.
We provide full-size mounting templates that specify hole locations. For uneven stone or corrugated metal walls, we use adjustable spacers (standoffs) to align the face of the letters while maintaining a consistent distance from the wall.
Yes. We supply premium Mean Well power supplies that accept wide input voltage ranges (100-240V AC, 50/60Hz) and output safe 12V or 24V DC to the LEDs. We match the power transformers to the local electrical standards of your region.
We seal the back plate of each letter using clear acrylic covers. These covers prevent dust, water, and insects from entering the letters while allowing the light to pass through.
We offer a 3-year warranty on all structural elements, LED modules, and power supplies. If a component fails within this period, we ship replacement parts via express courier at no charge, along with instructions for replacement.
