What GOA22 is, which special and underground lighting projects it fits, which regulatory requirements to verify and how to specify it.
GOA22 — Proiettore LED architetturale compatto 7-100W, corpo orientabile, 5 taglie (NANO → MEDIUM). GOA22 è la serie di proiettori LED architetturali di Lumeitalia con corpo compatto orientabile su staffa, disponibile in 5 taglie da 7W a 100W. Versioni monocromatiche 3000K (NANO, MICRO) e RGBW con controllo DMX512 (MINI, SMALL, MEDIUM). Ottima resa cromatica CRI Ra>80, vita utile >50.000 h, temperatura di esercizio -30°C ÷ +50°C, sicurezza fotobiologica Gruppo Esente RG0 (EN 62471). Ideale per illuminazione scenografica di facciate, monumenti, retail, hospitality e progetti architetturali di pregio. This Centro Studi briefing does not replace the product page: it frames the luminaire within the design process, from requirement definition to on-site verification.
GOA22 belongs to the special and underground lighting scope and is used in metro lines, stations, underpasses and critical environments. Three items always come first: classification of the scope under the applicable standard, the real installation geometry (spacings, heights, brackets or pitches) and the maintenance conditions planned over the installation life cycle.
Available distributions are 60° (NANO/MICRO). Optic selection is not a supply detail: it determines the uniformity achievable on a given geometry and therefore the number of light points required.
Photometric data: Specific photometric values (flux, efficacy, expected illuminance) are not published in generic form because they depend on configuration and installation geometry. Photometric files for calculation are available from the technical office at info@lumeitalia.it.
The requirement must be stated before product selection and repeated at commissioning with the same measurement method. A requirement written without a reference standard and without verification conditions is the most frequent cause of dispute at acceptance.
During installation the main variables are aiming, tightening of the fixings and correct execution of the electrical terminations. In operation, the maintenance plan must state the cleaning frequency of the optical surfaces, periodic gasket checks and how electronic components are replaced.
Declared marks and ratings for the range: CE, CEI EN 60598-1, CEI EN 60598-2-03, RG0 EN 62471. The related documents are supplied with the order confirmation.
GOA22 is a defensible choice when special and underground lighting requirements are stated, the calculation reproduces the real geometry and commissioning follows an agreed protocol. The full datasheet and quotation request are on the product page: https://lumeitalia.it/prodotti/goa22. The technical office is available for design requirement reviews at info@lumeitalia.it.
Special and underground lighting projects covering metro lines, stations, underpasses and critical environments. Suitability starts from scope classification and real geometry, not from datasheet comparison.
Photometric files for the proposed luminaires, declaration of conformity, declared lifetime data per IES LM-80 with its conditions, maintenance schedule and warranty terms.
It depends on the inherited geometry: existing spacings and heights must be checked with a dedicated calculation before confirming a one-for-one replacement. The technical office runs the check on request.
Because an out-of-context figure cannot be verified: the result depends on configuration, optic and installation geometry. Photometric files are available at info@lumeitalia.it.
