Lighting in infrastructure projects is much more than a convenience, it is a critical aspect of the safety of the installation. These projects have particular demands including resilient architectures, central battery backup, fail safe operation and comprehensive system monitoring and feedback. We have a significant experience in infrastructure projects including rail, airports and data centres. We have developed custom designs on top of standards based solution to achieve resilience with redundant path, duty standby and salt-and-pepper supplies. We have validated software protocols for fault monitoring and system recovery.
