CJ-401HS-S 400mm LED Yellow Flashing Traffic Warning Light

• High-Intensity Display Design
Featuring an oversized 400mm luminous aperture, this product provides a significantly higher visual duty cycle. The high-contrast yellow LED strobe signals offer exceptional penetration depth, assisting drivers in accurately capturing warning information from longer distances—even under low-visibility conditions such as heavy rain, dense fog, or twilight—thereby reducing the risk of misjudgment.

• Energy Efficiency & Longevity
The system's rectification circuitry is deeply optimized for energy efficiency, with the total rated power strictly maintained under 8W. By utilizing low-heat LED chips, thermal accumulation is minimized, effectively protecting internal circuits and slowing luminous decay to ensure stable light intensity during continuous, 24/7 operation.

• Weather-Resistant & Durable Housing
The lamp housing balances lightweight portability with high mechanical strength, facilitating easy installation at height. The PC/glass composite lens features a reinforced surface with superior impact resistance and UV protection, enabling it to withstand long-term exposure to wind and sand without clouding or cracking, preserving a clear optical path.

• DC Power Compatibility
Equipped with a standard 12V DC interface, the unit offers seamless integration with vehicle power systems, roadside monitoring control boxes, or solar energy storage modules. This high level of electrical compatibility simplifies wiring procedures for temporary traffic management scenarios and enhances on-site deployment efficiency.

• Reliable Protection Rating
Meets the IP53 industrial protection standard, featuring a structural seal specifically designed to resist outdoor dust accumulation and multi-angle precipitation. Core components are treated with anti-moisture and anti-corrosion coatings, ensuring the signal light maintains its performance metrics even in harsh, humid, or dusty outdoor environments.

Installation & Compatibility
Low-Voltage DC Power Design: Supports a DC 12V input, allowing for easy integration into existing traffic control systems or independent power supply lines.

High-Brightness Yellow Warning: Featuring a 400mm luminous diameter LED array paired with a PC/Glass lens, the unit provides a prominent flashing alert to enhance driving safety.

Durable & Lightweight Structure: The housing is made of high-strength plastic with a weight of approximately 7.5kg. Its IP53 protection rating ensures resistance to dust and light rain environments.

Flexible Mounting Options: Measuring 530 × 493 × 150mm, it supports both horizontal and vertical fixing, making it suitable for installation on standard traffic poles or brackets.

Energy Efficient: With a rated power of ≤ 8W, the low-power design ensures stable long-term operation while keeping maintenance costs low.

Applications
Urban Slow-Speed Zones: Used to prompt vehicles to decelerate, helping to improve overall traffic order.

Construction & Temporary Traffic Areas: The yellow flashing signal alerts drivers to construction zones or temporary changes in traffic patterns.

Schools & High-Pedestrian Areas: Warns drivers to prioritize pedestrian safety, effectively reducing the risk of accidents.

Industrial Parks & Factory Roads: Marks hazardous road sections or diversion channels to improve the safety of vehicle transit within facility grounds.
