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 that need a straightforward recessed format. The range is built around listed 3000K and 4000K model references, giving specifiers a simple route into warm or neutral white selection within one downlight family.
Model codes LUMI.001 to LUMI.008 cover outputs from 1075 lm to 4800 lm across 9.5 W, 17.5 W, 30 W and 46 W options. That spread makes the range more useful for projects comparing compact lower-output fittings against higher-output recessed IP54 downlights while keeping the same product language across schedules.
The switchable CCT downlight range includes 3000K and 4000K variants across several wattage steps, which gives specifiers a clearer route where one recessed IP54 family needs both warm and neutral white options. Where tunable white control is required, the range also lists a dedicated tunable white + 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.

Body And Trim Detail
Lumi switchable CCT body reference.
The recessed opal PC diffuser gives Lumi a clean downlight aperture that suits commercial ceiling schemes where a simple, low-visual-noise recessed appearance is preferred. The product image and listed codes keep that format consistent across the wider Lumi range.
The core body range covers 1075 lm to 4800 lm with 3000K and 4000K references across 9.5 W, 17.5 W, 30 W and 46 W steps. That makes the page more useful when comparing a lower-output recessed IP54 downlight against higher-output options without moving away from the same family.
Model, finish, control and emergency details are separated clearly in the coding structure. The base LUMI code identifies the output and colour temperature reference first, then suffixes are added for the required project variation, including universal bezel (/UB), tunable white + DALI (/T+DALI), mains dimming (/MDIM), Casambi wireless (/BTC) and the listed emergency variants. Custom configuration remains the route for non-standard arrangements outside the standard combinations.
