How Casambi enabled constant current drivers bring wireless Bluetooth control to LED downlights, spotlights and panels, and how to choose the right one.
Overview
A Casambi enabled constant current (CC) driver is a mains LED driver with a Casambi Bluetooth Low Energy radio built in. It powers an LED module at a fixed current, and can be switched, dimmed and grouped from the Casambi app on a phone or tablet, or from Casambi compatible wireless switches and sensors. There is no control wiring between the driver and the controls, and no gateway is needed.
Our Casambi CC range from Philips, Lifud and TCI covers 13W to 62W with output currents from 100mA to 1200mA. Lifud and TCI drivers set the current with a DIP switch, and Philips Xitanium drivers use SimpleSet. Philips and TCI models also accept a standard push switch for local control.
The technology
Every Casambi driver is a node in a Bluetooth Low Energy mesh. Each node relays messages to its neighbours, so a command from the app or a switch reaches every driver in the network, even those out of direct range of the phone.
The network is commissioned in the Casambi app: drivers are added, named and grouped into rooms, scenes and timers. The settings are stored in the network itself, so the lights keep working without the phone.
The driver then regulates a constant current into the LED module and dims it to the level requested. On models with a push input, a wired push switch adds local on/off and dimming.
Control options
How wireless Casambi control compares with DALI and Triac dimming for constant current LED fixtures.
| Feature | Casambi | DALI | Triac (phase-cut) |
|---|---|---|---|
| Control link | Bluetooth Low Energy mesh | 2-wire digital bus | Dimmer in the mains live feed |
| Control wiring | None | Separate DALI pair | None |
| Set-up | Casambi app on phone or tablet | DALI controller or software | None |
| Individual control | Yes, every driver | Yes, up to 64 per bus | No, per circuit |
| Scenes and timers | Yes, in the app | Yes, with a controller | No |
| Best for | Retrofit, flexible spaces, small to medium projects | New-build commercial projects | Simple dimming on existing circuits |

Our range
Choose the current to match the LED module, then check the output voltage range covers its forward voltage.
| Series | Output current | Output voltage | Power | Current set by | Dimming |
|---|---|---|---|---|---|
| Philips Xitanium 20W | 150 – 500mA | 24 – 54V | 20W | SimpleSet | 1 – 100%, push input |
| Philips Xitanium 36W | 300 – 1050mA | 24 – 54V | 36W | SimpleSet | 1 – 100%, push input |
| Lifud LF-ACB013B | 100 – 450mA | 2.5 – 42V | 13W | DIP switch, 8 steps | 0.1 – 100% |
| Lifud LF-ACB040B | 300 – 1050mA | 2 – 54V | 40W | DIP switch, 16 steps | 0.1 – 100% |
| TCI 127630 / 127631 | 300 – 1050mA | 10 – 54V | Up to 38W | DIP switch | 1 – 100%, push input |
| TCI 127645 / 127643 | 350 – 1200mA | 10 – 53V | Up to 62W | DIP switch | 1 – 100%, push input |
TCI 127631 and 127643 are the built-in versions. The TCI 127645 also accepts 110-127VAC input and has an NTC thermal sensor input and a 12V auxiliary output.
Benefits
Why Casambi is a popular way to add smart control to LED downlights, spotlights and panels.
Drivers talk to each other over Bluetooth, so only mains power is needed at each fixture.
The self-forming mesh is commissioned and controlled straight from the app.
Group lights, create scenes and set timers in the Casambi app, and change them at any time.
Flicker-free dimming down to 0.1% on Lifud models and ripple-free amplitude dimming on TCI models.
Set from 100mA to 1200mA by DIP switch or SimpleSet, so one driver covers many LED modules.
Philips and TCI models add local control from a standard retractive push switch.
Selection & set-up
Compare other dimming methods and complete the installation:
Wherever LED fixtures need flexible wireless control without new cabling.
Spotlights and downlights regrouped as displays change.
Scenes and timers for restaurants, bars and hotels.
Panels and downlights with wireless switches and sensors.
Smart control in existing buildings with no new control cables.
App-controlled downlights and feature lighting at home.
Modern lighting control where walls cannot be chased.
