A Low Location Lighting (LLL) system is designed to ensure that evacuation routes remain visible during emergencies. In the event of a fire, smoke can quickly reduce visibility, making it difficult to navigate. Additionally, power failures can lead to complete darkness, increasing the risk of panic and accidents. To enhance safety, a Low Location Lighting system provides illuminated guidance, ensuring that escape routes remain clearly marked.
An LLL system consists of photoluminescent or electrical strips and signs that direct individuals toward the nearest exits or assembly points. These systems are essential for maintaining safety, particularly in enclosed spaces where clear escape guidance is critical.
This FAQ article covers the most common questions about Low Location Lighting systems, helping you understand their function, regulations, and installation.
Ships, especially those carrying passengers, have numerous narrow hallways and compartments. In emergencies, confusion and panic can arise if evacuation routes are unclear. To prevent this, IMO & SOLAS regulations mandate that ships carrying more than 36 passengers must be equipped with Low Location Lighting.
For smaller corridors, a one-sided LLL system is sufficient, while hallways wider than two meters require lighting on both sides to ensure maximum visibility and guidance.
To remain effective, Low Location Lighting must be installed no more than 30 cm above the floor along escape routes. If placed higher, visibility may be compromised due to smoke accumulation in the event of a fire. Proper placement ensures that the lighting remains functional even in reduced visibility conditions.
Photoluminescent signs are safety signs that absorb and store ambient light from natural or artificial sources. When the surrounding light dims or is completely lost, these signs emit a visible glow, ensuring that safety information remains readable even in darkness.
These signs are widely used in LLL systems to guide occupants safely toward exits in emergency situations without relying on electrical power.
Photoluminescent LLL systems operate without electricity and rely on stored light energy to emit a glow in the dark. These strips and signs provide cost-effective and maintenance-free emergency lighting.
Electrical LLL systems, on the other hand, use LED-based lighting to mark escape routes at floor level. These systems remain in standby mode and activate either through remote control or a power failure, ensuring continuous illumination when needed.
A complete Low Location Lighting system consists of various components, each serving a specific purpose in ensuring clear evacuation routes. SafeSign offers a full range of LLL products, including:
LLL systems must comply with international maritime safety regulations, which vary based on vessel type and size. SafeSign ensures compliance with:

The installation of a Low Location Lighting system begins with creating a detailed escape route plan, which must be approved by the relevant authorities. Once approved, our specialists assess the site to determine the necessary materials.
Certified installers then implement the system, ensuring compliance with luminance performance standards. The inventory data is converted into signage plans, and associated costs are calculated using a management system linked to site drawings.
Regulations mandate that passenger vessels must have an operational LLL system. Both photoluminescent and electrical systems require periodic performance checks.
According to ISO 15370:2010 and IMO Resolution A.752 (18), all LLL systems must undergo luminance testing at least once every five years. This ensures that the system continues to provide adequate light output for safe evacuation.
Ultimately, however, these measurements are necessary to ensure that, in an emergency, all passengers and crew can find their way to safety—even in smoke-filled or dark conditions.
To maintain compliance, LLL systems must be tested to verify that they emit sufficient light. If a system fails to meet the required standards, it must be updated or replaced.
SafeSign’s trained and certified technicians use advanced equipment to measure and assess the luminance of your LLL system. Whether you have a photoluminescent or electrical system, we provide a turnkey solution, covering:
All services are performed in accordance with ISO 15370, ensuring full compliance with industry regulations.
