Design offices and contractors use this family to close out luminaires on time: stable photometric output, predictable thermal behavior, and mechanical footprints that actually fit canopies and trims. Ranges cover common caps (E27/E14, GU10, G13/G5, GX53, GU5.3) and voltage classes for 230 V AC and 12 V SELV circuits. Published data includes lumen packs from ~350 to 20 000 lm, CRI 80/90 options, CCT 2700–6500 K, power factor up to ≥0.90 on professional drivers, and ambient operation typically −20…+45 °C with Tc limits on the label. Packaging lists torque and conductor windows so ceiling teams don’t guess.
A19/A60 and candle forms sit in the 4–12 W band with 470/806/1055 lm nodes for office and hospitality; PAR and GU10 types address accent beams down to 10–24° with tight ANSI center/field ratios; G13/G5 LED tubes (EM/Mains/Universal) cover retrofit paths in existing battens. High-output sources for industrial bays reach 100–180 lm/W with surge protection to 2–4 kV L–N and 4–6 kV L/N–PE depending on class. Dimming variants support trailing-edge, 1–10 V, or DALI-2 through matched drivers. Flicker metrics are stated where relevant (PstLM ≤1.0, SVM ≤0.4 targets for offices) so visual comfort is predictable.

Legacy display and high-temperature niches sometimes keep MR16/GU10 or G9 capsules. Specify 12 V MR16 when optical precision and CRI≈100 are critical, use aluminum-backed reflectors to reduce heat soak, and match transformer type (electronic vs magnetic) to avoid acoustic noise. Typical life 2 000–4 000 h; check UV-stop glass for sensitive exhibits and verify luminaire Ta against enclosed ratings.
Sites with T8/T5 lines may still carry spares during phased LED conversion. Keep ballast wiring maps on record: EM ballasts pair with LED tubes rated for starter-bridge operation; HF gear calls for “HF-compatible” types or complete driver swap. For emergency circuits, verify lumen maintenance at 1 h and 3 h and confirm tube weight doesn’t overload bi-pin holders. Where color continuity matters, target Ra≥80 and Δu’v’ stability over 6 000 h.
Self-ballasted forms reference IEC 62560 for safety; LED modules and control gear align with EN 62031 and IEC/EN 61347-2-13/-2-7. Photometric data follows LM-79; source maintenance is projected via LM-80/TM-21 (common claims L70 30–50 k h; pro lines L80 50 k h when Tc is respected). EMC meets EN 55015 with immunity to EN 61547; harmonic limits per EN 61000-3-2 Class C for >25 W. Typical ingress protection is IP20 at the lamp, rising to IP44/IP65 at the luminaire level. Thermal notes: keep driver Tc 10–15 K below limit for warranty headroom; avoid enclosed cans unless marked “enclosed fixture rated”.
Open-plan offices: 3000/4000 K, UGR-compliant optics, and PF≥0.90 lamps on SENTRON breakers maintain low inrush diversity when many circuits switch together. Retail: GU10/PAR with 90 CRI and R9>50 preserve reds in textiles; narrow beams eliminate spill on wall bays. Education and healthcare: low-flicker drivers, CCT 3500–4000 K, and auxiliary contacts in the luminaire tied to S7/ET 200 for safe maintenance interlocks. Outdoor canopies: pick coated boards and conformal drivers; respect −30 °C start limits and specify 6 kV SPD on feeders.
Group control via KNX/DALI gateways is straightforward: DALI-2 drivers accept scene/DT8 tunable-white where required; KNX presence sensors feed channel logic while SENTRON metering tracks kWh per zone. For drives and VFD-heavy plants, segregate lighting feeders to reduce conducted emissions; add Type 3 SPDs near sensitive halls. Commissioning is faster when luminaires arrive with coded connectors and pre-cut whip lengths, and when DB schedules include inrush and breaker B/C curve selections.
Start with photometric need: target lux and uniformity, then pick lumen pack and beam. Choose CCT/CRI by task (90 CRI for fresh produce and fashion; 80 CRI for storage). Verify power factor and THD against building limits. Confirm dimming method and control topology early—mixing phase-cut and DALI on a floor creates churn. Check Ta and Tc; enforce clearance around drivers. For legacy housings, measure cup depth and clip geometry; many GU10 cans need short-neck bodies. Where rugged service is critical, specify siemens industrial lamps with elevated surge immunity and wide-range drivers. For quick fit-outs, pre-terminated harnesses outperform field crimping; if CFLs are still on drawings, swap to LED A-lamps and retire any request for siemens energy saving bulbs to hit energy KPIs without re-wiring.
We map lumen nodes, optics, CCT/CRI, driver type, and control protocol to your room data sheets, then surface live EU stock before you book ceiling access. Quotes usually return in about an hour with EAN/MPN, Tc limits, PF/THD, dimming method, and inrush figures stated—so breaker choices and cable sizing don’t drift mid-phase. Your portal shows lead times, order status, and downloadable price lists with validity dates. Approved clients can use post-payment up to 30 days. We consolidate by floor, zone, or fixture family to cut freight and site sorting, and your account manager cross-checks IP, surge class, emergency zoning, accessory fit, and mounting stacks against drawings so crates arrive build-ready and crews close the ceiling once.
