Technical description
Switchable CCT IP54 downlight specification for Lumi.
Lumi is a switchable CCT IP54 downlight with a recessed opal PC diffuser and a clean circular aperture for commercial ceilings. The four model codes provide 3000K, 4000K and 5600K output variants.
Lumi construction and mounting
Model codes LUMI.001 to LUMI.004 cover outputs from 1,475 lm to 3,500 lm across 13 W to 31.5 W, depending on the selected output package and colour temperature.
Recessed opal PC diffuser optics.
Output, optics and colour temperature
For switchable CCT downlight specifications, compare the model codes, outputs and available options below.
Lumi output is 1,475–3,500 lm.
System power options are 13–31.5 W.
Controls, emergency and project options
The switchable CCT downlight range includes 3000K, 4000K and 5600K variants across four output packages. Where tunable-white control is required, the range also lists a dedicated tunable-white and DALI suffix.
Control options include tunable white + DALI (/T+DALI), mains dimming (/MDIM) and Casambi wireless (/BTC). Emergency suffixes include 3-hour emergency (/EM), self-test / DALI emergency (/EMD), maintained emergency (/EMI) and DALI emergency (/EMDI), so the main model code can be paired with the required control and emergency arrangement.
Control options include Tunable white + DALI, Mains dimming, Casambi wireless.
