For bathrooms: use damp-rated LEDs (IP44 minimum, IP65 for shower areas), CRI 90+ at 3000K-4000K. Vanity lighting: vertical LED strips on both sides of mirror or an LED light bar above at 4000K, 1000+ lumens. Overhead: recessed 4-inch downlights at 3500K, dimmable. All fixtures must be GFCI protected per code.
Zone 1 (inside shower/tub): IP65 minimum. Zone 2 (within 60cm of shower): IP44 minimum. Zone 3 (outside zones 1-2): IP20 minimum (standard damp-rated). All zones require GFCI/ELCB protection per NEC/BS 7671.
4000K neutral white is best for vanity — it provides accurate color for makeup application and shaving. Some prefer 3500K as a softer compromise. Avoid 2700K for vanity (too yellow) and 5000K+ (too clinical, unflattering to skin tones).
Total: 75-100 lumens per square foot. For a 5x7 ft bathroom (35 sq ft): 2600-3500 total lumens. Vanity: 800-1500 lumens at 4000K, CRI 90+. Overhead: 800-1100 lumens, dimmable. Exhaust fan with integrated LED light: 500+ lumens minimum.
Yes. All bathroom lighting outlets (receptacles and switches) within 6ft of a water source must be GFCI protected per NEC 210.8. Use GFCI breakers or GFCI receptacles upstream of lighting circuits. This applies to vanity lights, exhaust fan lights, and shower trim.
