Add PoE to your lighting applications and take intelligent building systems to the next level
In intelligent building designs, PoE offers these benefits:
- Lower installation costs with greater flexibility; voltages less than 60 V may eliminate the need for an electrician, enabling plug-and-play capability
- Connected lighting; each light fixture's unique Internet Protocol address enables intelligent lighting control
- Achievable low standby power modes keep sensors and other intelligence on while lighting is off, enabling fast turnon
