Clevertronics Range

Selecting the Right Lithium Powered Product

There are many types of batteries used in Emergency lighting and it is important to understand the strengths and weaknesses of each battery chemistry to ensure you can get maximum value from your product.

Older battery technology such as Sealed Lead Acid, Nickel Metal Hydride and Nickel Cadmium provide inferior performance and carry significant environmental impacts compared to Lithium Iron Phosphate (LiFePO4) batteries.

Clevertronics has three range options for Emergency and Exit lighting products:


NiCd/NiMH (4 Years+)
EL (6 Years+)
CLP (8 Years+)
L10 (12 Years+)

*Based on 30ºC external ambient temperature, continuous operation.

L10 Lithium Nanophosphate®

The first and only Nanophosphate® powered product on the market

• Lowest total ownership cost
• 50% longer battery life vs any other lithium product
• 60% maintenance savings vs any other lithium product
• Standard Clevertest Plus

Clevertronics were global pioneers when they launched the L10 Optimum range of products in 2012 incorporating Lithium Nanophosphate® battery technology, becoming the world’s first Lithium powered product on the market. The L10 Optimum range has proven to be significant in the market due to the incredible maintenance savings that have been realised. The range is comprehensive and covers exit and emergency luminaires as well as a full range of battens, so you can ensure the facility can take full advantage of the savings available.

Since launch, over 500,000 L10 Nanophosphate fittings have been installed into 1,000’s of sites across Australia and NZ including, Melbourne Cricket Ground, Perth Children’s Hospital, Barangaroo Reserve, Legacy Way Tunnel and Marvel Stadium, and on-site real world results are exceeding bench-test performance predictions by a significant margin. Clevertronics Zoneworks XT Hive monitoring system provides unprecedented visibility into on-site product and maintenance performance, which is information that assists facility managers achieve compliance and helps Clevertronics in our drive for further innovation.

Testing and Development: Together with over 6 years of bench-testing data at elevated temperatures and on-site “torture testing” with specific trial-site partners, Clevertronics has cemented its position as the world leader in Lithium powered emergency lighting with its L10 Optimum range powered by Nanophosphate technology.

Michael Duce – National Systems and Engineering Manager from Clevertronics, provided some insight into the challenges of incorporating an LFP battery into an emergency light and ensuring long term reliability. “When we were embarking on this project we knew the reliability of the product was centred around the impact heat would have on the components inside the emergency luminaires so we put significant resources into redesigning products to place batteries away from heat sources. In the case of batten luminaires, we developed a thermally isolated section or POD at the end of the batten to house the LFP battery and the emergency LED light source.”

Testing was rigorous and Michael and his Australian-based team spent over two years testing the product before it was released on the market in 2012. Michael adds further details about managing the project. “The second challenge was to ensure we could incorporate the battery into the various range of fittings. Our customers needed a complete range of emergency, exits and battens fittings for their projects and to realise the 80% plus maintenance savings from the L10 range we needed to deliver the entire range as a package.

This was challenging from an engineering perspective due to the massive scale of the development task given the large number of different products in our range. It meant that we had to structure the development team to work on several product families concurrently and work very closely with the production team to ensure a smooth transition to full-scale production. To see the results now after having them onsite since 2012, provides great satisfaction especially being the global innovators.”
