If you’re updating a home or office, a thoughtful lighting plan for renovation transforms how spaces look, feel, and function. Renovation projects are the best moment to get lighting right — walls are open, ceilings accessible, and wiring can be future-proofed. This guide lays out a step-by-step, product-oriented approach so you can make confident decisions: from auditing existing light and choosing CCT/CRI to layout, controls, dimming compatibility, budgeting, and RFQ text you can copy-paste to suppliers and electricians.
I’ll explain the calculations, show what specs to demand, give room-by-room templates, and include maintenance and commissioning checklists. If you follow this lighting plan for renovation, you’ll avoid the common mistakes that force expensive rework later.
Why plan lighting during a renovation?
A renovation is the moment when changing ceiling locations, adding partitions, or altering floor finishes are all feasible with minimal cost. A proper lighting plan for renovation:
- Prevents awkward patch-ups and extra ceiling cuts later.
- Ensures fixtures and wiring are correctly placed for furniture and artwork.
- Allows you to choose the right controls (DALI, 0–10V, smart mesh) before finishes hide wiring.
- Let’s you optimize for energy and maintenance — good lighting saves money over time.
Think of the plan as the difference between a nice-looking room and a room that actually works for every activity it needs to support.
Start with an audit — the first step of any lighting plan for renovation
Before you design, document what you have. A short audit saves guessing.
- Inventory all existing fixtures — count and photograph each type (downlights, pendants, wall lights, exterior).
- Record technical details — lumen output, CCT (K), CRI, driver specs, dimming method, wattage, and model numbers where possible.
- Map control points — switches, dimmers, sensors, and their circuit groups.
- Measure current lux in key locations with a lux meter at typical task plane heights (desk, counter, bedside).
- Note problem areas — glare, dark spots, overheating, flicker, or inaccessible drivers.
This audit becomes the baseline for your lighting plan for renovation and will save time during quotation and commissioning.
Set targets — lux, CCT, and CRI are the foundations of your plan
A professional lighting plan for renovation starts with measurable targets.
- Lux (illuminance): the recommended targets (examples):
- Living/lounges: 150–300 lux ambient, 300–500 lux at reading points.
- Kitchen counters: 300–500 lux.
- Home office: 300–500 lux at desk plane.
- Dining table: 200–300 lux at the table surface.
- Hallways & stairs: 100–200 lux for safe navigation.
- Outdoor paths: 50–150 lux depending on use and security needs.
- CCT (color temperature):
- 2700–3000K — warm and cozy (living/bedrooms).
- 3000–3500K — neutral (dining, general areas).
- 3500–4000K — cool/neutral for task areas (kitchen, workshops).
- Tunable white is ideal in multi-purpose spaces.
- CRI (color rendering):
- CRI ≥ 90 for kitchens, bathrooms, retail, or anywhere colour fidelity matters.
- CRI 80–90 acceptable in secondary areas.
Write these values into the lighting plan for renovation so vendors and electricians work to the same targets.
Room-by-room recipes — apply the plan practically
Below are templates you can copy into your project plan. Each entry contains the typical lumens and fixture types you should consider.
Living Room
- Ambient target: 150–250 lux. Total lumens needed (example 20 m²): 20 × 200 ÷ 0.7 ≈ 5,714 lm.
- Fixtures: layered mix — recessed downlights (distributed), a statement pendant, floor/table lamps, and accent spots for art.
- Spec note: downlights 900–1,200 lm (CRI ≥ 90, 2700–3000K), dimmable (triac & DALI/0–10V if available).
- Control: scene buttons for Movie / Dinner / Reading.
Kitchen
- Ambient + task: counters 300–500 lux. Use under-cabinet linear strips (CR I90), recessed ambient, and pendants over islands.
- Spec note: under-cabinet strips 1,200 lm/m, 3500K, CRI 90.
- Layout tip: avoid downlights over islands that create shadow from cooks’ heads — combine central ambient and island pendants.
Bedroom
- Ambient: 100–200 lux. Bedside task 300 lux.
- Fixtures: warm ambient (2700K) + bedside adjustable reading lights + cove or toe-kick mood lighting.
- Control: bedtime scene, wake-up ramp with tunable white if desired.
Home Office
- Desk plane: 300–500 lux.
- Fixtures: neutral 4000K ambient + high-CRI desk lamp, glare-controlled linear fixtures if open-plan.
- Cable plan: include conduit for future data and power for monitors and lamps.
Bathroom
- Mirror plane: 300–500 lux.
- Fixtures: vertical vanity lights at face height (CRI 90+), IP44-rated downlights for ambient.
- Safety: Avoid single overhead lights that cast shadows.
Outdoors & Landscape
- Path lighting: 50–150 lux; porch 100–200 lux.
- Fixtures: IP65+ floodlights, warm garden lights (2700–3000K) for ambiance; motion sensors for security.
For each room, add the lumens calculation to the lighting plan for renovation and mark fixture locations on your drawings.
Controls & smart systems — plan the brain of your lighting
Controls transform static lighting into dynamic, efficient systems. Decide early whether your lighting plan for renovation will use:
- DALI / DALI-2 — best for commercial-grade control, addressable fixtures, and diagnostics.
- 0–10V — simple analog control for dimming and daylight harvesting.
- Triac / ELV — common for home dimming, but compatibility can be variable with LED.
- Wireless mesh (Zigbee, Bluetooth Mesh, Thread) — excellent for retrofit or where running control cables is costly; choose a single ecosystem to avoid fragmentation.
- Smart bulbs vs smart drivers: For whole-house control, prefer smart drivers or integrated smart luminaires; smart bulbs are good for lamps and small areas.
Add a controls diagram in your lighting plan for renovation with zones, switch types, and hub locations. Ensure key scenes run locally (without cloud) for reliability.
Dimming compatibility — the most common pitfall
Dimming is often where renovations go wrong. The lighting plan for renovation must include:
- A compatible dimmer list for each LED product — manufacturers often test specific dimmers.
- Decide whether you’ll use wall dimmers or centralized control. If wall dimmers, select LED-rated models and test drivers in the actual circuit.
- For high-performance dimming and integration, prefer DALI-2 or addressable drivers.
- If you keep old dimmers, expect flicker or poor low-end dimming — test first.
Always test a sample fixture and the dimmer in situ during the renovation before committing to a bulk order.
Thermal and ceiling considerations — don’t trap heat
LED lifetime depends on good heat management. A good lighting plan for renovation checks:
- IC (insulation contact) rating: If the ceiling is insulated, choose IC-rated housings or new downlights designed for insulation contact.
- Driver location: Prefer accessible driver mounts (above the ceiling or in a service hatch) to enable future replacement without ceiling damage.
- Enclosed fittings: Some retrofit trims are not suitable for totally enclosed housings — heed manufacturer ratings to avoid derating or failures.
Wiring, conduit & future-proofing — what to add now
When renovating, add little bits of infrastructure that make future changes painless:
- Run conduits (empty sleeves) to key fixture locations for future wire pulls.
- Install extra junction boxes with access panels near clusters of downlights so drivers can be replaced.
- Add a dedicated lighting circuit for large zones to simplify control and fault isolation.
- Run low-voltage control cabling (DALI bus or 0–10V) to planned hubs if you intend to use them.
Include these items in the contractor scope in your lighting plan for renovation to avoid later disruption.
Product specs to demand — make RFQs compare apples-to-apples
When you issue RFQs as part of your lighting plan for renovation, require suppliers to send technical data and matching tests:
- Lumens (lm) and efficacy (lm/W).
- CCT (Kelvin) and CRI.
- L70 life hours and warranty duration.
- Dimming compatibility and flicker percent.
- Driver type and replaceability.
- UGR (where glare matters) and beam angles.
- IP rating for wet or outdoor fixtures.
- IES files for photometric layouts.
Here’s a copy/paste RFQ line you can use:
“Supply 10 recessed downlights, 900 lm, 3000K, CRI ≥ 90, 95 lm/W, dimmable (triac & 0–10V), flicker <5%, L70 ≥ 50,000 hrs, replaceable driver, include IES files and dimmer compatibility report. Install, commission, and providea 5-year warranty.”
Put that in your lighting plan for the renovation procurement pack.
Mock-ups, commissioning & acceptance — make them contract items
A renovation-grade lighting plan for renovation specifies commissioning steps:
- Mock-up area: install a sample zone with finishes, furniture, and actual fixtures to verify CCT, beam, and dimming.
- Photometric verification: request IES-based lux maps and on-site lux checks for critical zones.
- Dimming commissioning: test and document dimming behavior and scene recall.
- Handover pack: as-built wiring diagrams, fixture/driver serials, dimmer model list, and maintenance plan.
Include these steps in your contract and withhold final payment until commissioning documents are provided.
Maintenance & warranty — what to plan after renovation
- Keep one spare driver and one spare lamp/trim per fixture family for the first 2 years.
- Schedule visual checks quarterly and a photometric audit annually for high-use areas.
- Document everything: model numbers, supplier contacts, batch numbers, and installation photos.
- Confirm warranty terms for LED modules vs drivers vs finishes.
A disciplined maintenance plan protects your investment and should be part of your lighting plan for renovation.
