AR111 bodies keep the classic Ø111 mm footprint with G53 two-pin base, so trims, snoots, and gimbals from legacy fittings stay in play. Typical wattage nodes sit at 10/12/15/18 W with outputs around 900–1 600 lm depending on beam and CCT. Beam sets cover 8° punch for vitrines, 15°/24° for merchandise “hot spots,” and 36°/45° for broader pools. CCT packs 2700/3000/3500/4000 K; CRI 80 runs daily duty, while CRI 90 with healthy R9 is stocked for food, wood, textiles, and skin tones. IP20 at the lamp is standard; face IP rises with the host luminaire and accessory ring.

Two optical architectures dominate. TIR lens engines deliver tight cut-off, high CBCP, and clean edge gradients; they’re the go-to when you size by centre-beam at the working distance (not lumens). Glass/metalized reflectors read more “halogen” in heritage trims and are forgiving in direct view. Expect CBCP from ~2 000 cd (15 W, 24°) to well past 4 000 cd (15 W, 8°); publish the throw distance and target lux so the shop floor lands right the first time. Accessories—honeycomb, soften, and spread films—control near-field sparkle on glossy stone, lacquer, and foils without losing beam shape.

spl lighting high power led spots drivers and control

Most AR111 LEDs are 12 V nominal and accept AC/DC. In small groups, LED-rated electronic transformers with low minimum load work; for longer multi-head runs, a constant-voltage 12 V driver per circuit is steadier. If your spec needs scene control, pair external drivers on 1–10 V or DALI-2 DT6; lamp-integrated dimming on phase-cut prefers trailing-edge (RC) for quiet low-end. Pro bins target PF ≥ 0.90 (≥12–15 W), THD ≤ 15 %, and flicker metrics around PstLM ≤ 1.0 / SVM ≤ 0.4 for camera-heavy retail. Keep secondary leads short; long twin-lead runs shave dimming headroom and tilt CCT on low levels.

spl lighting commercial spot lamps applications and layouts

Retail aisles and tables: 24° at 3000/3500 K, CRI 90, aimed to cross-light and lift texture without washing verticals. Galleries and vitrines: 8°–15°, CRI 90 at 3000 K with honeycomb; set CBCP to reach 1500–2500 lx at distance without glare for viewers. Hospitality bars and lobbies: 36°/45° pools at 2700/3000 K; keep luminance under control with baffles in low ceilings. In mixed estates, harmonise CCT/CRI with panels and linears so colour doesn’t jump between layers.

Construction, thermal path, and life

Die-cast or heat-loaded polymer crowns move heat straight off the board; Tc pads are marked and must remain ≤ 85 °C. Fronts are PMMA/TIR or tempered glass with UV-stable seals. Typical lifetime claims: L70/L80 25–50k h at Ta 25 °C (LM-80/TM-21 sourced). Operating window −20…+40 °C; insulation against the crown shortens life and nudges colour on CRI-90 engines. Surge ride-through is usually 1–2 kV L-L; where lifts/VFDs share the board, add an upstream SPD.

Standards and interfaces you’ll actually use

LED source/module: EN/IEC 62031; driver performance: IEC 62384; integrated gear: EN/IEC 61347-2-13.
Retrofit safety/marking where applicable: EN/IEC 62560.
EMC: EN 55015 / EN 61547; mains quality: EN 61000-3-2 / -3-3
Photobiological safety: EN 62471 (RG0/RG1 at typical outputs).
Holders follow IEC 60061 G53 geometry; use T-rated lampholders in insulated or shallow cans.

Series map and assortment logic

TIR Accent — 8°/15°/24°, highest CBCP, matte crowns to hide glare; CRI 90 focus for fashion, leather, timber.
Reflector Classic — 24°/36°/45°, halogen-like look, forgiving in direct view; strong pick for heritage trims.
Warm-Dim — 3000 → ~1800 K curve for dining and lounge zones; lower peak lm by design but very convincing ambience.
Short-Neck — reduced overall length for tight gimbals and shallow plaster rings.
Across the families, bins are held to ≤ 3 SDCM so replenishment lots don’t drift on colour.

Planning notes that cut commissioning time

Size by CBCP at working distance, then pick wattage. A 15 W 8° can outperform a higher-lumen 36° on the target plane.
Declare dimmer topology per area. Mixing RL/RC on one floor causes chatter at low end.
Keep secondary runs short on 12 V; voltage sag is the usual reason spots won’t dim smoothly.
Match CCT/CRI to adjacent layers; a 3500 K accent over 3000 K ambient reads cold.
For bathrooms/wash-adjacent zones, use sealed front rings in the host downlight; the lamp remains IP20.

Procurement and B2B kit notes

Quote each node with: beam (°) + lumen/CBCP at target distance + CCT/CRI + cap/base (G53) + dimming note (RC/1–10 V/DALI-2) + overall length + surge class. Add accessory codes (honeycomb/soften/spread) on the same line; they’re the first items scuffed late in a program. For transformer estates labelled as spl lighting g53 spotlight bulbs, include minimum-load data and the approved transformer list to avoid low-end flicker.
