LED wired lighting – hard-wired, line-voltage or low-voltage luminaires permanently connected to the building’s mains or to a remote driver – is now the default for every commercial segment.
Below is a concise “where & how” guide written for electrical contractors who buy from Beauty (STC) Manufacturing Co., Ltd. All data refer to our standard 220-240 V / 120 V constant-current and constant-voltage portfolios (model prefixes BL-, SL-, PL-, HL-).
1. WHERE TO USE LED WIRED LIGHTING
HOTELS (24 h operation, high CRI, silent dimming)
• Lobby & porte-cochère: surface 30 W-50 W track spots, 3000 K, CRI ≥90, 24° beam for artwork.
• Corridors: 6 W-8 W 3-inch downlights, 1.2 m on center, 120 lm/W, corridorMODE (30 % after 23:00).
• Guest-room headboard: 14 W/m 24 V COB strip, <5 mm pitch, wired to Class-II SELV driver behind TV wall.
• Bathroom mirror: IP44 14 W 600 mm vertical pendants, CRI 95, R9>50 for make-up accuracy.
• F&B & ballroom: 25 W-40 W DALI COB theatre spots, Tm30 ≤2 SDCM, flicker-free <1 % at 1 kHz for broadcast.

2. INSTALLATION CHECKLIST FOR CONTRACTORS
A. Pre-wire
1. Verify nominal vs. actual line voltage: our drivers accept ±10 %, but chronic 250 V reduces lifetime 25 %.
2. Segregate circuits: keep DALI, 0-10 V, mains in separate trunking; crossover only at luminaire terminal.
3. Earth integrity: <0.5 Ω at every metal part; our Class-I luminaires have twin earth terminals—use both.
B. Driver location
4. Remote-driver models (BL-RDxxx): mount within 20 m to avoid V-drop; use 2.5 mm² stranded for 24 V rails, max 5 % V-drop.
5. Ambient limit: Ta 50 °C at driver; if ceiling void exceeds, derate 0.25 W/°C or relocate to conditioned riser.
C. Thermal management
6. Downlight cut-out: maintain 100 mm free air above heat sink; insulated ceiling? use IC-rated (BL-ICxx) or build plaster-board box.
7. Linear runs: leave 5 mm expansion gap every 2 m; aluminum profile temperature must stay <70 °C at 35 °C room.
D. Dimming & control
8. DALI: 22 V ±6 V, max 250 mA, 2×1.5 mm², bus-powered. Do NOT mix with phase dim on same line.
9. 0-10 V: use shielded twisted pair, isolate mains from control with Beauty (STC) IS-1 interface to avoid ground loop flicker.
10. Flicker check: record with smart-phone 240 fps; target PstLM ≤1, SVM ≤0.4 for hospitality & broadcast zones.
E. Testing & commissioning
11. 100 h burn-in on site: captures early failures, stabilizes lumen output (+3 % typical).
12. Record serial & driver address (DALI short address) in hand-over log; QR code inside every Beauty (STC) fitting links to e-passport.
13. Emergency: monthly 5 min / yearly 3 h test; our EM-xxx modules auto-report via DALI-2.
F. Maintenance forecast
14. L90B10 at 50 000 h ≈ 12 years @ 12 h/day; schedule cleaning every 24 months with anti-static cloth; avoid ammonia-based glass cleaner on polycarbonate diffusers.
3. COMMON SITE MISTAKES WE SEE
• Using 1.0 mm² T&E for 40 W track—results in 8 V drop, pink-shift at far end.
• Installing IP20 strip in bathroom zone 1—always specify IP65 + 24 V SELV.
• Connecting 3-phase track on single 16 A breaker—neutral overload when loads are unbalanced; use 4-pole RCBO.
• Skipping surge protector: 2 kV urban, 4 kV rural; our drivers survive 6 kV differential, but LED array may still fail.
4. TOOLING & ACCESSORIES FROM BEAUTY (STC)
• Pre-wired 3 m WHIPS (H05RN-F 3×1.0 mm²) with WAGO 2060 Series push-in—saves 4 min per fitting.
• Magnetic spirit-level template for 3-inch downlight—guarantees 90° ceiling alignment.
• DALI-2 handheld (model BC-DALI01) for quick short-address scan & fade test—rental free with 500+ pc projects.
