What Makes a Down Light “Dimmable”?
Not all down lights can be dimmed. To avoid disappointment (and flickering!), always confirm that the light itself—and its supporting components—are marked as dimmable. At Future Light, we stock a wide range of certified dimmable options to suit South African homes.
“Don’t assume your existing dimmer switch will work—trailing-edge dimmers are best suited for dimmable LEDs. Replacing the driver might also be needed for low voltage installations.”
Retrofit Friendly: Keep Your Existing Fittings
Worried you’ll need to rip out your ceiling fittings just to upgrade? Good news: most Dimmable LED Down Lights—like our popular Coastal LED Down Light—fit beautifully in existing ceiling cut-outs. Simply confirm that your current transformer or driver is LED-dimmable-compatible.
