Expertise in lighting control systems for smart cities

Nyx Hemera Technologies develops and installs smart city lighting control systems for road tunnels, underpasses and other infrastructure where energy savings, reduced operating costs, increased safety, optimized operations and sustainability are imperative.


Formally founded in 2008, the professionals at Nyx Hemera Technologies have unique expertise in power line control and communication, the core technology used by Nyx Hemera Technology, for its flagship TLACS solution, which offers market-leading levels of reliability, stability and efficiency.

Installed in Asia, Canada, the United States, Europe and South America, the scalable TLACS solution controls more than 50,000 luminaires worldwide – from one of the world’s longest tunnels, the Kallang – Paya Lebar Tunnel in Singapore, to simple parking garages in the Bronx, NY where security was an issue.
