Ceiling and wall bodies from Steinel are built to go in quickly, take abuse during commissioning, and run for years without drift. Drivers are predictable on inrush, PF sits ≥0.9, and control paths cover DALI-2, 1–10 V, and switched lines on 220–240 V AC. Sealing options span IP20 for dry rooms to IP65/IP66 for semi-exposed areas, with IK08–IK10 where impact is expected. Crews like the consistent terminals (0.5…2.5 mm² copper), clear marking, and bezels that keep their line after service openings.
Round bulkheads, square slabs, micro-profile cylinders, and utility plates share hole geometry and fastener sizes, so mixed rooms line up without re-drilling. Outputs run roughly 1,000–4,000 lm for interiors and 5,000–10,000 lm where long throws are needed. With corridor optics and standby dimming, steinel surface mounting lamps handle stair cores, classrooms, and common areas on the same accessory set.
Opal diffusers deliver low-contrast general light; micro-prism lenses hit UGR targets in offices; asymmetric “wall-lift” options push vertical lux for wayfinding. Colour quality is CRI 80 standard with CRI 90 on request; CCT 2700–6500 K, MacAdam ≤3 SDCM for tone consistency. For retrofit grids, steinel wall and ceiling lights keep shallow bodies and centred entries so existing conduits and cut-outs aren’t disturbed.
Bodies use UV-stabilised polymers or powder-coated aluminium with stainless fixings in salty or ammonia-rich air. Gaskets are closed-cell EPDM or silicone; membranes equalise pressure on IP65 lids. Lifetimes track at L80/B10 50,000–100,000 h (LM-80/TM-21 projections) depending on drive current and thermal path. On mixed driver banks, steinel surface mounted luminaires show calm dimming with DALI-2 broadcast or addressed scenes.
Efficacy typically 110–140 lm/W at nominal currents; dim-to-off standby draws stay low for daylight-linked control. Emergency versions support maintained and non-maintained modes per EN 60598-2-22, with addressable test on DALI-2. Heat is handled with generous interface area so junction temperatures stay in the efficient band. Where EPC targets bite, steinel led surface lamps combine high lm/W with occupancy/daylight logic for quick kWh gains.
Integral PIR or HF heads provide 360° coverage at 2.5–3.0 m; corridor lenses constrain activation to the working path. Hold times run 10 s–60 min; lux thresholds 5–1000 lx; fade-to-standby keeps 10–30% background for safety. Commissioning is via handheld IR or app/Bluetooth®, and profiles clone floor-to-floor. In schools and housing, steinel motion sensor surface lights preserve manual override for cleaners while sensors manage background light.
Offices and education maintain 300–500 lx at the work plane with daylight harvesting; healthcare prefers sealed bezels for wipe-down; residential cores use standby levels to avoid blackouts. DALI-2 is the default where analytics and fine zoning matter; broadcast works when wiring is tight; 1–10 V supports legacy drivers. For neat handovers, steinel indoor surface lighting keeps connector positioning and inrush predictable for Type B/C MCBs.
Façades, entries, and canopies need predictable IP and corrosion resistance. Outdoor compounds are UV-stable, lenses resist yellowing, and shields control glare on pedestrian routes. Surge levels step up to 4 kV L-N where storms and long runs are expected. For coastal or plant-adjacent sites, steinel exterior surface fixtures pair sealed bodies with breathable membranes so the gasket doesn’t pump under temperature swings.
Sensors and fittings act as nodes: addressed DALI-2 for scenes and reporting, broadcast for quick zones, 1–10 V where legacy gear remains. KNX gateways expose occupancy and levels to the BMS; inputs accept inhibit from AV systems. Bluetooth® templates let crews push identical parameters across floors without reopening gear trays. For mixed vendors, neutral DALI-2 certification preserves interoperability.
Stair cores benefit from corridor optics and fade-to-standby; classrooms need scene recall with quiet dimming; social housing wants resilient bulkheads with HF where airflow upsets PIR; logistics corridors favour elongated beams and masking near glass. Verify trunking pitch and live-end orientation; confirm panel depth and connector type on retrofit tiles; keep emergency circuits upstream of dimming.
We align pricing to room schedules and expose live EU stock before crews are booked. Quotes land in about an hour with EAN/MPN so variants stay locked. Your portal shows lead times, shipment status, and downloadable price lists with stable validity windows. Approved accounts can use post-payment up to 30 days. We consolidate partials to cut freight, and a dedicated account manager cross-checks optics, control interface, emergency mode, IP/IK class, mounting kits, and accessory sets against your drawings so cartons arrive site-ready. We serve France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands with tracked lead times and predictable pricing.
