Why Fusion
Why specify this low-profile architectural LED downlight?
Fusion provides one low-profile downlight family for fixed-white and tunable-white lighting schemes. Standard 3000K and 4000K models are complemented by 2700K to 6500K tunable-white versions, while TouchDIM, DALI and Casambi options support project lighting control. Three-hour, self-test, DALI and maintained emergency variants are also available.
The 9-model family combines 1,025–4,550 lm, 3000K / 4000K / 2700–6500K and 9 listed configuration choices without changing the core product identity.
A larger downlight format without losing configuration flexibility
Base model, control, emergency and accessory decisions remain visibly separate in the configurator.
This keeps the fitting code readable while retaining the breadth of the current product range.
Large-diameter format
Broad ceiling presence for larger commercial interiors.
Low-profile bezel
Clean RAL9016 visible finish around the optical system.
Nine model choices
Multiple output and colour-temperature configurations.
Controls and emergency
Control, emergency and performance suffixes remain explicit.
