A revolution in home lighting
✓ One ELV* system for all LED luminaires and switches/sensors
✓ Power supply and control via SINGLE TWO-WIRE CABLE
Any switch or sensor in the system can control any luminaire or luminaires following a preset program. Any elements can be connected anywhere to the bus: single two-wire cable.
Create modern, safe LED lighting in the house. Say goodbye to smart lighting systems' complicated setup and maintenance but embrace their convenience and flexibility.
* extra-low voltage
A revolution in lighting wiring
✓ Low-cost installation work and materials
✓ An electrician's license is not required
✓ Easy installation
✓ Smooth and trouble-free operation
Money saving
Installation up to 5-x cheaper? It's possible!
Electric license-free installation
The system uses extra-low voltage (ELV), so the contractor and installer do not require electrician licenses. An unskilled laborer is much cheaper
Typical wires and components
Two-conductor 18 AWG speaker cable, ordinary wire routing methods and connection options
Labor saving
Simple and quick installation available to everyone. Technology allows you to create a modern, flexible, and reliable lighting system quickly.
"One cable to rule them all..."
One cable is one cable. Not two similar ones, not two different ones. One mount, one route, one pull-through
The system uses only one two-wire cable (bus) to power and control the luminaires and to connect switches/sensors
"One connector to bring them all..."
First, clamp the connector on the bus wire. Secondly... the light, sensor, and switch are already connected
Trouble-free
Smooth and trouble-free operation through a reliable wired connection for instant luminaire response to commands and complete noise immunity.
Service-free and battery-free
All devices and sensors are wired and powered from a common line. After a power failure, the system automatically returns to operation in a few seconds
Internet-free
Full autonomy
Hidden costs-free
No subscription fees, no subscriptions, no additional software packages. The system works immediately and permanently
