When it comes to underground construction projects, having reliable underpass lighting solutions can make the difference between a safe, efficient worksite and a dangerous, costly delay. Duraline’s specialized hand lights and temporary lighting systems are engineered specifically for the demanding conditions found in tunnels and underpasses, where standard lighting simply won’t suffice.
Built for the Underground Environment
Working in tunnels and underpasses presents unique challenges that require specialized equipment. These environments are typically wet, cramped, and subject to heavy machinery traffic. Duraline’s hand lights are designed to withstand these harsh conditions with construction that prioritizes durability and safety.
Each hand light features solid rubber molding that creates a waterproof seal, making them suitable for wet locations commonly found in underground construction. The vapor-proof construction ensures that moisture, dust, and debris won’t compromise the lighting system’s performance, even in the most challenging underground conditions.
277V AC Power: Extended Reach for Mile-Long Applications
One of the standout features of Duraline’s tunnel and underpass lighting solutions is their ability to operate at 277V AC. This higher voltage capability is crucial for underground projects where lighting needs to extend over vast distances – up to one mile long in some cases.
Traditional lighting systems suffer from significant voltage drops over long distances, resulting in dim, inadequate illumination at the far end of the run. Duraline’s 277V AC system maintains consistent brightness throughout the entire length of the installation, ensuring that workers have proper visibility whether they’re at the entrance or deep within the tunnel.
The system utilizes special LED lamps that can operate from 120 to 277 volts, allowing the construction string lights to perform far beyond what normal voltage drop requirements would typically allow. This flexibility means contractors can adapt their lighting setup to match the specific power requirements of their project without sacrificing illumination quality.
Engineered for Safety and Durability
Safety is paramount in underground construction, and Duraline’s hand lights incorporate several features designed to protect both the equipment and the workers using it. Each lamp socket features a crush-proof steel ring that prevents damage from accidental drops or contact with heavy machinery, such as truck tires, a common hazard in tunnel construction.
The lamp sockets are soldered for optimal wattage without requiring cuts to the main cable, maintaining the integrity of the electrical system while ensuring maximum light output. This solid construction approach reduces the risk of electrical failures that could leave workers in dangerous darkness.
The heavy-duty 600-volt SOOW cable is molded in solid rubber, providing exceptional durability against the abrasive conditions found in tunnels. This cable can handle the constant movement, dragging, and positioning required in active construction zones without compromising electrical safety.
Flexible Configuration Options
Duraline’s underpass lighting solutions offer remarkable flexibility in configuration. The hand lights can be molded to T drops, allowing them to be hung overhead to provide area lighting while simultaneously offering power access points for workers’ tools through switched or non-switched trouble lights.
This dual functionality is particularly valuable in tunnel work where space is at a premium and every piece of equipment needs to serve multiple purposes. Workers can access both lighting and power from the same drop, reducing the amount of equipment needed and simplifying the setup process.
The system also supports alternating drops of light and power, creating a comprehensive infrastructure that supports both illumination and tool operation throughout the work area.
High-Performance LED Technology
Modern tunnel projects demand high-quality illumination, and Duraline delivers LED technology that produces up to 5,000 lumens at 5,000 Kelvin. This bright, daylight-balanced lighting improves visibility and reduces eye strain for workers spending long hours in underground environments.
The LED boards are integrated with waterproof rubber molding and include the driver, LED, and Lexan lens in a single, durable package. This integrated approach eliminates potential failure points while providing consistent, high-quality illumination that traditional incandescent bulbs simply cannot match.
Proven Performance in Demanding Applications
Duraline’s temporary lighting systems have been tested in some of the most challenging environments, including shipyards, mines, highway construction worksites, and bridge projects. This real-world experience translates directly to tunnel and underpass applications, where the same demanding conditions require equally robust solutions.
The ability to string lights together for long distances makes these systems ideal for major tunnel projects where continuous illumination is essential for both safety and productivity. Whether the project involves a short underpass or a mile-long tunnel, Duraline’s lighting solutions can be configured to provide consistent, reliable illumination throughout the entire length.
Built For The Toughest Of Environments
For contractors and project managers working on tunnel and underpass projects, Duraline’s hand lights represent a purpose-built solution that addresses the unique challenges of underground construction. With 277V AC capability for extended reach, crush-proof construction for durability, and flexible configuration options for versatility, these underpass lighting solutions provide the reliability and performance that underground projects demand.
The combination of advanced LED technology, waterproof construction, and proven durability makes Duraline’s hand lights an ideal choice for any tunnel or underpass lighting application where safety, reliability, and performance are non-negotiable requirements.
