RADIANT 4

The RADIANT PRO 4.81 (from the STARK PRO series) is a high-performance outdoor LED solution engineered for demanding architectural integrations. Featuring a precise 4.81mm pixel pitch and an extraordinary brightness level of 7000 nits, this display ensures exceptional visibility even under direct sunlight. Its defining characteristic is the Total Front Maintenance architecture, allowing for ultra-slim wall-mounted installations where rear access is impossible. By eliminating the need for a rear technical corridor, the RADIANT PRO 4.81 maximizes space efficiency while delivering high-contrast, vibrant imagery thanks to its premium SMD1921 LED components.

State-of-the-Art Outdoor LED Engineering

At Pixelight, we prioritize visual stability and component longevity. The RADIANT PRO 4.81 utilizes SMD1921 (Surface Mounted Device) technology, optimized for outdoor durability and wide viewing angles. Unlike entry-level panels, this series features a 3840Hz high refresh rate, which eliminates flicker in broadcast environments and ensures smooth motion reproduction.

Enhanced Durability and Optical Performance

• Luminance & Contrast: With 7000 nits, the display maintains a superior contrast ratio, preventing "washed-out" colors during peak daylight hours.
• Mechanical Precision: The 500x250mm modular design allows for seamless alignment, crucial for maintaining pixel integrity across large surfaces.
• Heat Dissipation: The aluminum chassis is engineered for passive cooling, protecting the internal IC drivers and extending the lifespan of the LED diodes.

While some applications benefit from GOB (Glue on Board) for impact resistance, our SMD1921 selection focuses on high-brightness output and ease of individual pixel repair, making it the professional choice for large-scale outdoor advertising.

Versatile Outdoor Applications

The RADIANT PRO 4.81 is the go-to solution for fixed outdoor installations where aesthetics and space-saving are paramount. Its slim profile is ideal for:

• Retail Facades: High-end luxury storefronts that require bright, color-accurate displays without intrusive back-structures.
• Urban Digital Signage: DOOH (Digital Out Of Home) advertising in city centers where pedestrian space is limited.
• Corporate Headquarters: Sleek digital branding integrated directly onto building skins or technical walls.
• Transportation Hubs: Information boards in airports or train stations that require front-access for quick, non-disruptive maintenance.

Thanks to its IP65-rated protection, it thrives in varied climates, providing reliable 24/7 operation for international projects.

Technical Integration & Maintenance Advice

To ensure the peak performance of your RADIANT PRO 4.81 installation, our Pixelight technical team recommends the following:

• Optimal Viewing Distance: With a 4.81mm pitch, the minimum viewing distance is approximately 5 meters. For ideal clarity and "retina" effect, 8-10 meters is recommended.
• Power Management: Ensure a stable power supply. For outdoor setups, we advise using a power sequencer to manage inrush current during startup.
• Front Maintenance: Use the dedicated vacuum suction tool for module removal. This prevents physical stress on the gold-wire bonds of the SMD LEDs.
• Calibration: Use a Novastar or equivalent high-end controller to fine-tune the color uniformity and grayscale after installation to compensate for environmental light conditions.
