DALI LED emergency conversion kits transform standard LED fixtures (panels, downlights, tubes) into addressable, self-testing 3-hour emergency lights, essential for compliance in public/commercial buildings. They feature LiFePO4 batteries, automatic self-testing via DALI protocol, and constant power output. These kits allow for remote monitoring and reporting, simplifying maintenance and compliance.

Key Features and Benefits

DALI Compatibility: Enables integration into DALI lighting control systems for automated testing and status monitoring, reducing manual testing costs.

Emergency Operation: Provides 3 hours of illumination (usually at reduced output) during power failures.

Versatility: Compatible with various LED types, including panels, downlights, and linear tubes.

Long-Life Batteries: Typically utilize LiFePO4 batteries, which offer longer lifespans and lower power consumption compared to traditional alternatives.

Auto-Adjustment: Automatically adjusts output current to match the specific LED load, ensuring optimal performance.
Installation: Designed for easy installation, often featuring plug-and-play connectors, and can be mounted inside the luminaire or remotely in the ceiling void.

Technical Specifications

Duration: Usually 3 hours.

Input Voltage: Typically 220–250V AC.

Standards: Complies with DALI standards IEC 62386-101, 102, and 202.

Safety: Features such as self-extinguishing covers and over-voltage protection.

Common Applications

Commercial offices
Public buildings
Warehouses
Escape route lighting
Retrofitting existing non-emergency fixtures

Liteplan are the largest, privately owned emergency lighting component supplier to the UK market, whilst also shipping their products to a worldwide customer base. Established in 1994 by the late Bill Green, the company was successfully run by Bill’s right hand man, Peter Ray for many years.

Their Business Development Director, Adrian Spicer is a long standing and well respected figure in the world of emergency lighting. His knowledge and stature within the industry are invaluable to them.

Liteplan’s wealth of knowledge extends many years. Their Technical Manager, David French BSc. sits on the committee at ICEL and works closely with The LIA. Their Product R&D Manager, Osman Özgür Rakibet, PhD, takes control of Liteplan’s product road map. His knowledge is steering their evolution and maintaining their position as the innovators of the emergency lighting sector.

Many of Liteplan’s engineers have worked with the company for over 20 years, constantly striving to progress through the our ever evolving CPD scheme to stay at the forefront of the ever changing world of legislation.

Liteplan proudly design all of their products in-house, making product evolution a constant and seamless process. They employ over 60 local personnel, many of whom have been with them for the majority of their existence and they also pride themselves on their unrivalled delivery satisfaction level.

Their 40,000 square foot factory enables them to carry a huge level of stock, thereby fulfilling even the largest of orders with haste. They recently acquired additional warehousing adjacent to their headquarters near London’s M25. This will fuel Liteplan’s global expansion plans for many years to come.
