Spot Light
DUNA
DUNA is a spot light family within the LUMIBRIGHT Lumi Indoor collection. The current catalogue groups 1 article codes under this family, including LB2798. For LB2798, published values include power: 5W; colour temperature: 3000K; IP rating: IP20; dimensions: Ø85mm. Each article represents its own physical model; dimensions and electrical or optical options must be checked against that exact code. Compare the DUNA articles using the specification table and individual model pages before adding them to a lighting schedule. Wattage, colour temperature, protection rating and installation dimensions are catalogue values, not a guarantee that every combination can be ordered. Where a value is not published, request the relevant model documentation rather than assuming it matches another article. Confirm the selected configuration, driver requirements, installation detail and project documentation with the specification team before ordering.
