Lights for cable trays

Use indirect, enclosed, or LED lighting that minimizes heat and electrical interference while providing adequate visibility along cable tray runs. Recommended Light TypesLED Strip or Linear LightsEnergy-efficient and low-heat, reducing the risk of overheating cables. Can be mounted along the sides or underneath cable trays for uniform illumination.

Suitable for industrial, commercial, and utility installations.

Enclosed or Vapor-

Tight Fixtures

Protects against dust, moisture, and accidental contact with cables. Ideal for environments with high humidity, chemical exposure, or outdoor installations.

Indirect Lighting

Reduces glare and prevents direct heat on cables. Can be mounted on walls or ceilings to illuminate the tray area without interfering with cable integrity.

Placement and Safety Considerations

Maintain Clearance: Ensure lights are installed at a safe distance from the cable tray to prevent heat buildup and allow for maintenance access. Avoid Electromagnetic Interference (EMI): Use fixtures with low EMI emissions, especially near sensitive control or data cables. Compliance with Standards: Follow IEC 61537 for cable tray installation and local electrical codes for lighting in industrial or commercial spaces.

Environmental Suitability: Choose materials and finishes for fixtures that match the environment, such as corrosion-resistant housings in chemical plants or offshore facilities.

Practical Tips

Use motion-sensor or task lighting in areas with infrequent access to reduce energy consumption. For long cable tray runs, consider multiple evenly spaced fixtures to avoid shadows and ensure clear visibility. Ensure fixtures are securely mounted and do not obstruct cable installation or maintenance.

By selecting low-heat, enclosed, and appropriately positioned lighting, you can maintain safety, visibility, and compliance while protecting the integrity of cables in the tray system.
