2. Installation Method
Step 1 – Preparation
De-energise the car; lock-out/tag-out main breaker. Record serial number and LED colour code.

Drill 68 mm Ø cut-out in car ceiling panel. Insert TL-CL4W-C1 until snap-ring locks. Ensure gasket sits flush for IP54 seal.

Step 3 – Wiring
Route 2-core 0.75 mm² cable through PG9 gland. Connect red (+24 V) and black (0 V) to car-top lighting circuit. Torque screws 0.6 N·m.

Step 4 – Commissioning
Power-up; LED should illuminate uniformly. Measure lux at floor level (≥100 lx). Apply calibration sticker dated by technician.

3. Daily & Preventive Maintenance
Daily (Building Staff)
Visual check – LED bright, no flicker. Ensure lens clean.

Monthly
Wipe lens with 70 % IPA; check gasket integrity. Measure lux (≥100 lx).

Quarterly
Measure supply voltage (24 V ±1 V) and current (<200 mA). Cycle light 100× for thermal stress.

Annually
Replace desiccant pack. Perform full photometric test; log lux values.

4. Replacement Cycle & Indicators
| Duty Cycle | Replace Every | Hours | Warning Signs |
| Residential | 7–8 years | 50k | Lux <70 lx, flicker |
| Commercial | 5–6 years | 35k | Yellowing, >230 mA |
| High-traffic | 3–4 years | 25k | Cracks, IP54 failure |

Replace immediately if:
– Lux <70 % of original
– Physical damage or water ingress
– Repeated “lighting fault” logs
– Temperature >70 °C

Maintain one spare TL-CL4W-C1 per 25 cars for <4-hour response.
