Lighting Installation in California

Per fixture for straightforward swaps (replacing a pendant or fitting downlights into existing wiring), hourly for exploratory or fault work, and quoted per project for new circuits, dimmers across rooms, or outdoor schemes. Height, ceiling access and whether wiring exists at the point drive cost more than the fixture itself.

Rules vary by country — some allow DIY like-for-like swaps, others make almost all fixed wiring licensed work. Beyond legality: anything involving new cabling, no earth wire present, unfamiliar switch loops, or bathroom zones is genuinely worth a professional regardless.

Priced per point: cutting in, wiring and fitting each recessed light, with the first costing more than each additional one on the same run. Fire-rated housings, insulation-contact (IC) ratings, and dimming add per-unit cost. A typical room takes 4-8 downlights.

No — standard ceiling boxes/hooks hold only a few kilograms. Heavier fittings need a rated support fixed to structure, and stairwell or double-height installs need scaffolding or specialist access. Tell the installer the fixture weight and location when getting quotes.

Swapping the switch is quick, but the dimmer must match the load type — LED lamps need trailing-edge dimmers and 'dimmable' rated bulbs, or you get flicker and buzz. Smart dimmers may also need a neutral at the switch, which older homes often lack.

Bathrooms have zoned rules: fittings near showers and baths must carry appropriate ingress protection (IP) ratings, and many jurisdictions restrict who may do the work. Choose IP44 or better near water and confirm the installer knows the zone requirements.

Like-for-like fixture swaps: generally no. New wiring, new switch or fixture locations, and new circuits: generally yes, with inspection. Rules are municipal — a quick call to your building department settles it, and licensed electricians handle permits routinely.
