Your TRUSTED Advisor

By making lighting controls accessible, we believe this

Enables good lighting design

Provides operational benefits

Enhances wellbeing in the lit environment

Casambi Advantages

Bluetooth low energy mesh network (independent of WIFI)

Standalone software platform, not aligned to luminaire manufacturers

Provide complete flexibility for luminaire product solutions, for the engineer, consultant, architect and client

Future proof lighting controls, by providing luminaires with individual control then you are able to make site configurations based on a change of working environments or site configuration

Significant energy savings through scheduling and demand responses

Better occupant experience in task tuning and personal control of light level management

Improve building operations available through luminaires' providing performance data, helping tune the system as well as critical health data that enables predictive maintenance

No Wires Required

Without the need to pull wires, wireless network lighting controls offer significantly lower deployment costs. Decreased labour and material costs, minimum disruption to business operations during installation, and reduced ongoing maintenance costs combine to bring substantial savings to building owners and managers, particularly in retrofits.


The ideal network lighting control system is often one that can start small and then scale, in both functionality and size. Once deployed, wireless systems are far more extensible than wired counterparts and can more easily add advanced controls and expand to meet changing business needs and occupant requirements.


The cost of deploying, or even piloting, legacy networked lighting control systems has limited their adoption. Bluetooth® mesh removes the need for centralized controllers, lowering the cost of componentry and reducing upfront labor and installation expenses, allowing designers and specifiers to quickly deliver value to building owners and end users.


With Bluetooth® technology native in 100% of smartphones and tablets, system integrators and installers can use simple, user-friendly, commissioning apps that communicate directly with nodes on the network, eliminating the need for specialized engineering expertise as well as internet access and cloud platforms to support installation and operation of the system.


Wireless systems allow for placements of equipment where distance restrictions or accessibility would make a wired solution impractical, if not impossible. In addition, wires are fixed, but spaces and layouts changes, and lighting control systems must adapt with them. Wireless systems are more easily reconfigurable and provide superior flexibility compared with wired offerings.


The same Bluetooth® radio embedded in lighting control devices can also be used to implement advanced building services, such as indoor navigation and asset tracking, enabling networked lighting control systems to shift from a single-function solution to a platform for data-driven smart building services that bring benefits far beyond illumination.


Best-In-Class Scale, Performance & Reliability

Bluetooth® mesh networking was specifically designed with large-scale networked lighting control implementations in mind. Three key features help separate the scale, performance, and reliability of Bluetooth mesh from other wireless lighting control technologies and provide the resiliency needed by installers, building managers, and end-users in commercial installations.

  • A decentralized control architecture distributes intelligence to all end devices, eliminating single points of failure to prevent system-level outages

  • A unique publish/subscribe message addressing approach significantly lowers messaging traffic on the network, leading to greater network scale and performance

  • A managed flood message relay approach enables lighting networks to scale to thousands of nodes while maintaining high performance and reliability
