Stairwell Vapor Tight Light

Description

Stairwell Vapor Tight LED Light, IK10 Impact Resistance, Motion Sensor Emergency Mode, Anti-Slip Reflector, Safe Staircase Guidance Lighting

The Stairwell Vapor Tight Light is engineered to offer reliable, high-intensity illumination in the most demanding conditions. It is built as a Stairwell Vapor Tight LED Light with an IP65-rated housing and IK10 impact resistance to create a resilient barrier against dust, water, and mechanical shock. Regardless of whether mounted inside stairways, transit tunnels, or underground parking ramps, its debris- and water-proof vapor-tight housing protects against water and debris penetration, and its LED driver delivers up to 220 lm/W luminous efficacy, reducing energy consumption and maintenance cycles.

built around premium SMD2835 LED chips (LM-80 certified) and an 86% transmittance PC diffuser, this light source delivers non-glaring, even light distribution. The slip-resistant reflector design integrates a highly textured interior surface that scatters light evenly, avoiding hot spots and minimizing slip risks on stair treads—a great complement to safe staircase guidance lighting. In safety-critical applications, a stainless-steel or high-strength PC clip option strengthens the fixture against impact in case of accidental contact, while a spacious terminal block (5.0 mm hole) allows for simple wiring and field maintenance.

Stairwell Vapor Tight Light basic features

Durability & Protection

• UV-Resistant Design: The anti-UV milky PC diffuser and PC base are made to resist yellowing over time, maintaining a clean and attractive appearance even after long periods of exposure to direct sunlight.
• Weatherproof & Impact-Resistant:With a weatherproof rating of IP65 and high impact resistance of IK10, the light is impervious to harsh weather and physical strain. A silicone seal also makes it more resistant to moisture and dust, ideal for outdoor and demanding environments.
• High Diffusion Rate:The milk cover diffuses light up to 88% and, through its striped design, creates even and soft illumination across the area. This reduces deep shadows and creates a cozy, well-lit environment.
• Easy Mounting and Installation:The lamp comes with extended mounting slots for stainless steel clips, offering flexibility in mounting. The gear tray is secured tightly by the PC knob, making installation very easy. The hooker base also makes it easy to handle during mounting and ensures that the gear tray does not fall during maintenance for safety.
• Durable Construction:A 0.5mm thick iron tray with white paint provides a robust construction with high reflectivity for concentrated lighting effectiveness.

Enhanced Lighting Efficiency

1. Advanced LED Technology:Utilizing high-brightness 200lm/W SMD2835 LED chips, LM-80 approved for low light degradation, the fixture achieves over 120lm/W efficiency. The color rendering index (RA >83) delivers rich, life-like illumination.
2. Personalised PCB Design: The fixture consists of a 1.6mm thick FR4 PCB with 35mil thickness copper for enhanced heat transfer as well as efficiency overall.
3. Simple Maintenance: SMD twin-hole connectors offer plug-and-play simple insertion without soldering and with easier maintenance. Easy replacement without need for orientation due to symmetrical light strip construction.
4. Temperature-Resistant Parts:White nylon rivets with high-temperature resistance are able to handle temperatures of up to 185°C, maintaining the light’s longevity and safety even under harsh conditions.
5. Wiring for Effectiveness: The light fixture uses wiring in parallel loops, which reduce the likelihood of total failure when an individual LED chip fails. All wiring utilizes >0.8mm² high-temperature, UL-approved, 100% copper conductor wiring for enhanced performance and longevity.

Power & Efficiency

• High-Power Driver:The IEC-certified 60W DC constant current isolated driver features a high power factor of >0.9 and provides ample margin for a long lifespan. The clip-on installation, half-power DIP switch, and plug-and-play connectors make replacement and maintenance straightforward.
• Emergency Functionality:The light is equipped with a high-temperature-resistant, large-capacity lithium battery designed specifically for emergency lighting, providing over 3 hours of backup. A battery compartment with plug-and-play terminals ensures easy battery replacement when necessary.
• Microwave Motion Sensor:Featuring a highly sensitive 5.8 GHz HF microwave sensor, the fixture offers adjustable parameters for brightness, time, and distance. This enhances energy efficiency by automatically adjusting the lighting based on motion, ensuring optimal performance while reducing energy consumption.
• Emergency Status & Testing:The light includes an external high-brightness emergency status indicator and a test button, making it easy to monitor and test the fixture during maintenance.

Versatile Installation & Accessories

1. Linkable Installation:The fixture supports linkable installation, allowing for a seamless connection between multiple lights without additional wiring. This feature simplifies large-scale installations.
2. High-Quality Mounting Clips:The light comes with 304 stainless steel mounting clips for surface mounting and nickel-plated stainless steel screws, ensuring a secure installation in both indoor and outdoor settings. It also includes an IP65 weatherproof plug to block off pre-cut wire outlets when wiring exits from the back.
3. Retail-Ready Packaging:The light is individually packaged in cardboard, protected by a PP environmental bag to prevent dust and scratches. For bulk orders, a large double-corrugated cardboard box is used for up to 9 units, making it suitable for retail and wholesale distribution.

FAQs:

1. What kind of environments are best suited for the Stairwell Vapor Tight Light?

It excels in high-humidity, dusty, and high-impact environments—parking garages, subway stairwells, and service tunnels—because of its IP65 seal and IK10-rated case. It resists pressure washing and intentional bumps without compromise to performance.

2. In what way does the motion sensor emergency mode enhance safety?

With an internal 5.8 GHz HF microwave sensor, the light is either in one of three modes: full-bright occupancy, low-level standby (20 %), or off. In the event of a loss of power, it will go to emergency output (3.6 W) instantly, with >3 hours of guiding light, which is critical for safe evacuation.

3. Can I connect several fixtures in a continuous run?

Yes—all units have cableable quick-connect ends, facilitating simple daisy-chaining for runs of any length. Installation is made simple in long halls or multi-flight stairwells without external wiring issues.

4. What is the maintenance routine?

Thanks to the clip-fix driver design, on-site repair is a matter of minutes. Simply release the end cap knob, pull out the driver assembly, and swap with a spare—no shutdown to full power necessary. The yellowing-resistant high-transmittance PC diffuser reduces frequency by half.

5. Is customization available for buying in high volume?

Yes. Through factory-direct production, buyers can customize color temperatures (3000K–6000K), emergency pack designs, or integrated control gear. Large quantities also have good prices and special after-sales service for convenient rollout.
