Quick Answer
Outdoor lighting installation in Melbourne costs $150–$600 per light point installed by a licensed electrician. A simple garden path light on a low-voltage transformer runs $80–$200 per light (DIY-friendly). Hardwired LED downlights or feature lights cost $150–$400 per point installed. A full front/back yard lighting package (8–12 lights) typically runs $1,500–$4,000.
Outdoor Lighting Installation Costs in Melbourne
Good outdoor lighting does three things for a Melbourne home: it improves security, lifts street appeal, and makes alfresco areas usable after dark. In newer estates like Clyde North, Officer and Cranbourne East, outdoor lighting is increasingly a standard expectation — and in older suburbs like Frankston and Carrum Downs, it’s an easy upgrade that adds real value.

What Affects Outdoor Lighting Costs?
1. Mains vs Low-Voltage vs Solar
The biggest cost driver is whether you need hardwired 240V work (electrician required, $150–$500/light) or low-voltage/solar (DIY possible, $30–$150/light). For path and garden feature lighting, low-voltage is almost always the right choice. For security floodlights, soffit downlights, and pergola feature lighting, 240V hardwired is needed.
2. Cable Run Length
A downlight installed in a soffit directly above a pre-existing circuit adds around $150–$250. If the nearest circuit is 15m away and requires trenching across a lawn or drilling through walls, the cost per light rises to $300–$500. In double-brick homes in older Frankston and Noble Park suburbs, running cables through walls can be particularly time-consuming.
3. IP Rating Requirements
Outdoor lights must meet minimum IP ratings. Victoria requires IP44 for covered outdoor areas and IP55+ for exposed areas (rain). Pool lighting needs IP68. Always verify the IP rating of any light before purchasing — non-rated lights fitted outdoors are both illegal and a safety risk.
DIY Outdoor Lighting Options
You don’t need an electrician for every outdoor lighting upgrade. These options are fully DIY:
- Solar garden lights: Spike directly into garden beds. No wiring. From $20 at most hardware stores.
- Low-voltage path lights: 12V transformer plugs into a standard GPO. Lights connect with push-in connectors. Brands like Lumascape and Garden Lights NZ sell quality kits.
- Plug-in festoon or string lights: Plug into a weatherproof outdoor GPO. Perfect for pergolas and alfresco areas.
- Battery-powered sensor lights: Mount anywhere with screws — no wiring. Good for side gates and sheds.
Top 10 Tips and Gotchas
- Plan your zones first: Group lights on separate circuits or transformer zones so you can control front garden, backyard, and alfresco independently.
- LED-only for outdoors: Halogen outdoor lights are outdated — LED uses 70–80% less power and lasts 5–10× longer. Replace any remaining halogen path or flood lights.
- Choose warm white (2700K–3000K) for garden: Cool white (5000K+) looks harsh in garden settings. Warm white creates a more welcoming ambience for SE Melbourne outdoor entertaining.
- Don’t over-light: One strong floodlight washing out an entire backyard looks cheap. Use layered lighting — ambient (string lights), task (path lights), and accent (uplights for trees/features).
- Sensor floodlights deter break-ins: Motion-activated LED floodlights are proven deterrents. Install one on the rear of the house and one covering the driveway.
- Check transformer capacity: Low-voltage transformers have a watt limit. A 100W transformer running 10 × 8W lights is at capacity — add a second transformer rather than overloading.
- Bury low-voltage cables correctly: Landscape cables should be buried 150mm deep in PVC conduit, even at 12V. Lawnmowers and garden forks find buried cables.
- Smart timers pay for themselves: A $40 timer plug on your low-voltage transformer means lights come on at sunset and off at midnight — no wasted electricity.
- Avoid cheap solar on south-facing fences: Solar lights need direct sunlight to charge. South-facing fences in Melbourne rarely get enough sun for reliable solar operation.
- Pool lighting is specialist work: Pool lighting in Victoria must comply with AS/NZS 3000 and be installed by a licensed electrician with pool electrical experience. Don’t DIY.

Frequently Asked Questions
Do I need an electrician for outdoor lighting in Melbourne?
Only for hardwired 240V lights. Solar lights, plug-in festoon lights, and 12V low-voltage transformer-powered path lights are all DIY-legal. Any light connecting directly to 240V mains — downlights, hardwired floods, hardwired wall lights — must be installed by a licensed electrician in Victoria.
How much do solar garden lights cost in Melbourne?
Decent solar garden lights cost $20–$80 each — brands like Morryde and Eglo at Bunnings or Mitre 10 perform well in Melbourne’s climate. Cheap $5 solar spikes from discount shops rarely last more than one summer. Spend at least $25–$30 per light for reliable performance.
What IP rating do outdoor lights need in Melbourne?
IP44 minimum for covered areas (under a pergola or eave). IP55+ for exposed areas (open to rain). IP68 for pool or water feature lighting. Always check the light’s IP rating before buying — fitting non-rated lights outdoors is illegal under Australian wiring standards.
How many path lights do I need for a front garden?
Space path lights 1.5–2m apart for a Melbourne standard 8m front garden path — that’s typically 4–6 lights. Don’t overdo it: the goal is guiding footsteps, not runway lighting. Alternate sides of the path for a more natural look.
Can I put festoon lights on my pergola?
Yes — plug-in festoon lights connected to a weatherproof outdoor GPO are fully DIY. Make sure the GPO is rated for outdoor use (IP44+) and the light cable is rated for outdoor use. Use a timer plug to automate the lights so you’re not paying for overnight electricity.
Final Thoughts
Start with low-voltage path lights and solar accent lighting — these are DIY-friendly, cheap, and immediately lift your home’s night-time kerb appeal. For security and alfresco entertaining, budget for a licensed electrician to install sensor floodlights and hardwired pergola downlights. A well-planned outdoor lighting scheme costs $1,500–$3,000 and transforms how a Melbourne home looks and feels after dark.
