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
