Why Room-by-Room Lighting Is the Only Approach That Works
I made the mistake of buying the same bulbs for every room when I moved into my first house. The result: my bedroom was too bright, my kitchen was too dim, and my bathroom lighting made me look like a different person. Lighting needs vary dramatically by room because each space has a different primary activity. Cooking needs bright, shadow-free light (3000K, 4000+ lumens). Sleeping needs warm, dim light (2700K, 1000-2000 lumens). Grooming needs neutral light at eye level (3000K, 600+ lumens at the mirror). Here's how I approach each room.
Kitchen Lighting: Layered Brightness for Cooking and Eating
The kitchen needs three layers: ambient (recessed or flush-mount ceiling lights), task (under-cabinet lighting for countertops), and accent (inside glass cabinets or above open shelving). I use 3000K throughout for consistency. My Kitchen Lighting guide covers the specific placement, lumen requirements, and fixture recommendations. The key insight: under-cabinet lighting is the single most impactful kitchen upgrade you can make. It eliminates countertop shadows completely.
Bathroom Lighting: Vanity Positioning and Waterproofing
Bathrooms are the most technically demanding room for lighting because of moisture requirements. Every fixture must be rated for its zone (IP65 inside the shower, IP44 within 60cm). I've documented the exact placement and waterproofing requirements in my Bathroom Lighting guide. The most common mistake: relying on a single overhead light that casts shadows at the mirror. Side sconces or a backlit mirror are the solution.
Outdoor Lighting: Security vs Landscape
Outdoor lighting serves two entirely different purposes: security (bright, motion-activated, covering entry points) and landscape (low, warm, accenting plants and pathways). These require different fixtures, different brightness levels, and different color temperatures. My Outdoor Lighting guide covers both, including IP ratings, transformer requirements, and wiring options. Security lights need 1800+ lumens at 3000K. Landscape lights work best at 100-300 lumens per fixture at 2700K.
