Bundle Offer!
Purchase the LIFX Switch with LIFX Warm to White Downlights for a Bundle Offer!
- LIFX Switch and 4 x Downlights for $399
- 2 x LIFX Switch and 10 x Downlights for $799
All items must be purchased in the same cart transaction to receive bundle offer, excludes delivery charges. Offer valid until March 24 2021.
Wall Switches must be installed by Licensed electrician where a neutral wire is required.
For that price I'd expect installation to be included.
