Please note
- Luminaire manufacturers may also be able to equip pendants with DALI or DALI-2 drivers
- The best practice for connecting floor and table lamps to mains is to use luminaire outlet sockets (traditional or DCL-type)
- Make sure that floor, table, and reading lights are ordered without integrated switches
