How much will LED light replacement cost?
Answer a few questions and we’ll email you an Auckland price range.
Still running halogen downlights? Each one is costing you power. EECA says LED bulbs use up to 85% less electricity than traditional incandescent or halogen bulbs, and across a house full of downlights that gap shows up on every bill.
The catch is that a downlight isn’t a bulb you twist out. It sits in a hole in your ceiling, usually with a gap cut in the insulation around it, and the fitting, its transformer and your dimmers decide whether the swap is quick or needs more work. The prices below are our published guide range for Auckland retrofits through our property maintenance services, with the parts that move the number spelled out.
How Much Does It Cost to Replace Downlights With LED?
The cost per downlight depends on three things: the fitting itself, the electrician’s labour, and how many lights you’re doing in one go.
| Cost Component | Typical Range (NZD) |
|---|---|
| LED downlight fitting (supply) | $10–$50 per light |
| Electrician labour per light (retrofit) | $30–$60 per light |
| Electrician service/callout fee | $80–$150 per visit |
| Electrician hourly rate (Auckland) | $120–$180 per hour |
| Total per light (bulk replacement, 10+) | $39–$70 per light |
| Total per light (small job, 2–5 lights) | $70–$110 per light |
The per-light cost drops significantly when you do more lights at once. That’s because the electrician’s callout fee and setup time get spread across more units. On our guide range, a job of 10 or more lights runs $39 to $70 a light, against $70 to $110 a light for two to five.
Why the Price Range Is So Wide
A $39 per light quote (common for bulk replacements of 10+ lights) usually includes a basic NZ-certified LED fitting and straightforward swap into an existing hole. A $110 per light quote might involve a premium fitting with colour-temperature selection, dimming capability, and additional wiring work — or it might just reflect a small job where the callout fee pushes the per-unit cost up.
Always ask what’s included: the fitting, the driver, the installation, and the electrical safety certificate.
💡 Property tip: Downlight cut-outs aren’t one size. If your existing holes don’t match the cut-out on the new fitting’s spec sheet, you’ll need conversion plates or a different fitting, so check before your electrician quotes.
Whole-House LED Upgrade — What Will It Cost?
Downlight counts vary a lot from house to house. Here’s what a full LED upgrade comes to at different counts on our guide range, set against EECA’s figure for what each LED saves over its life:
| Number of Downlights | Estimated Total (installed) | Lifetime running-cost saving (our working on EECA’s $100–$300 per bulb) |
|---|---|---|
| 10 lights | $500–$700 | $1,000–$3,000 |
| 20 lights | $900–$1,400 | $2,000–$6,000 |
| 30 lights | $1,300–$2,100 | $3,000–$9,000 |
| 40 lights | $1,700–$2,800 | $4,000–$12,000 |
EECA puts the lifetime saving at $100 to $300 for each bulb you replace with an LED, against $39 to $110 to have a downlight fitted on our guide range. Bulk jobs sit at the low end of the fitting cost, which is where the sums work best, and you stop climbing ladders to replace blown halogens.
The Energy Maths
EECA’s LED lighting guidance gives three numbers worth knowing. LED bulbs use up to 85% less electricity than traditional incandescent or halogen bulbs. An LED lasts around 30,000 hours, against about 2,000 hours for an incandescent bulb. And each bulb you replace with an LED can save $100 to $300 in running costs over its life, depending on the wattage of the bulb it replaces.
Those are national figures, so your own saving depends on how many hours your downlights are on and the unit rate on your power bill. Check both before you count on the top of that range, especially for lights in a hallway or spare room that are rarely on.

Replacing Halogen Downlights With LED: What’s Actually Involved
Most of the downlights we swap out across Auckland are one of two types, and which one you have changes the job. Get this wrong and you end up with flickering lights or a fitting that won’t sit in the hole.
GU10 vs MR16: Know Which Halogen You Have
GU10 downlights run straight off 240V mains and have two stubby pins that twist to lock. An MR16 (also sold as GU5.3) runs off low voltage (12V) through a separate transformer tucked above the ceiling, and has two thin, sharp pins. GU10s are the simpler upgrade: in many cases you can drop a compatible GU10 LED lamp into the existing fitting. MR16s are trickier, because the old halogen transformer often won’t drive an LED cleanly and causes flicker or buzzing.
Why a Full Fitting Swap Usually Beats a Bulb-Only Change
For a handful of GU10s in good fittings, a lamp swap can be enough. Across a whole house, or on any MR16 setup, replacing the entire downlight with a modern integrated LED fitting is almost always the better call. EECA gives the same advice for recessed downlights: replace the whole fitting rather than just the bulb, because the biggest saving comes from cutting heat loss into the ceiling. You get a matched LED and driver (no transformer-compatibility guesswork), a longer warranty, and the option of an IC-F rated fitting that ceiling insulation can sit directly over. That last point is the one landlords miss: it lets you close the insulation gaps the old halogens forced you to leave, which feeds straight into Healthy Homes insulation performance.
💡 Property tip: Before you buy fittings, count how many are GU10 and how many are MR16, and measure the cut-out diameter of a couple of holes. Getting that list to your electrician up front means one visit, not two.
How Much Does an Electrician Charge to Change a Light Fitting?
On a small lighting job, the hourly rate and the call-out matter more than the fitting. Our guide to trade rates across Auckland house repairs puts Auckland electricians at $120 to $180 an hour, with a standard-hours call-out of $80 to $150. Spread that over two lights and it dominates the bill. Spread it over twenty and it almost disappears, which is why our per-light range runs from $110 down to $39.
One light, a few lights or the whole house
| Job | What drives the price | Our guide range |
|---|---|---|
| Two to five downlights | The call-out and set-up time shared across very few lights | $70–$110 per light |
| 10 or more downlights in one visit | The call-out shared across every light, working room to room | $39–$70 per light |
| Whole house, 20 to 30 downlights | As above, plus checking dimmers and any MR16 transformers | $900–$2,100 |
A ceiling light or pendant rather than a downlight
Changing a single ceiling light or pendant for an LED fitting is priced the same way: labour for the fitting plus the call-out. Where the new fitting goes in the same position on the existing wiring, it’s a short job. Moving the light, adding a new one or running a new switch means new wiring, which takes longer, and your electrician will tell you which certificate the job needs (more on that below).
Three questions that make lighting quotes comparable
- Is the call-out included in the per-light price, or added on top?
- Does the price include the fitting, or only the labour to install one you supply?
- Will the electrician check your dimmers and any MR16 transformers, and is replacing them priced in?
💡 Property tip: Give the electrician a room-by-room count of every downlight you want changed when you ask for the quote. A per-light price only means something once the call-out has a number of lights to spread across.
LED Replacement for Landlords and Rental Properties
If you own a rental property in Auckland that still has halogen downlights, upgrading to LED is a straightforward decision. The energy savings benefit your tenant (lower power bills), and the longer lifespan means fewer maintenance callouts for blown bulbs.
Insulation Compatibility — This Matters
This is where LED upgrades become more than just a lighting decision. Older halogen downlights usually need gaps in the ceiling insulation around them, because EECA notes the heat from older downlight bulbs is a fire risk. Those gaps are where heat escapes through the ceiling.
Modern LED downlights rated as IC (insulation contact) or IC-F (insulation contact — fire rated) can have insulation laid directly over them. That means replacing halogens with IC-rated LEDs lets you close those insulation gaps, improving energy efficiency twice: once through lower lighting costs and again through better ceiling insulation performance.
Healthy Homes compliance note: The Healthy Homes Standards require ceiling insulation to a minimum R-value of 2.9 in Auckland, and existing ceiling insulation installed before 1 July 2016 must be at least 120 mm thick. Tenancy Services also says existing insulation must be in reasonable condition, with no mould, dampness, damage or gaps. If your rental has halogen downlights with the insulation cut back around them, ask your insulation installer whether the gaps need attention when the fittings are replaced. Whether a property complies is Tenancy Services’ call: see the insulation standard on tenancy.govt.nz.
Bundling LED Upgrades With Other Maintenance
If you’re already having electrical work done at a rental property, or scheduling a tenant turnover refresh, adding an LED upgrade at the same time saves a separate callout fee and reduces total cost. We can bundle LED replacements with general property maintenance, painting and insulation work through our Auckland network.
💡 Property tip: When you compare fittings, check the rated life in hours and the warranty on the spec sheet, and buy from a supplier who can show the fitting meets NZ electrical safety requirements. A cheap fitting with no paperwork is a false saving in a ceiling you can’t easily get back into.
What to Know Before You Upgrade to LED
Colour Temperature — Warm vs Cool
LED lights come in a range of colour temperatures measured in Kelvin (K). For residential use in NZ, the most common choices are 3000K (warm white, similar to halogen and cosy) and 4000K (cool white, brighter and more clinical). EECA’s rule of thumb: warm white is more comfortable in homes, and cool white works best where contrast matters. That usually means warm white in living areas and bedrooms, with cool white kept for work areas such as a garage or workshop.
Some modern LED fittings offer selectable colour temperature: you can switch between warm and cool with a simple toggle. These cost a little more but give you flexibility.
Dimming — Check Compatibility
Not all LED downlights are compatible with existing dimmer switches. If you have dimmers, make sure the LED fittings and the dimmer are compatible, or you’ll get flickering, buzzing, or limited dimming range. Your electrician can advise on this and replace incompatible dimmers if needed.
Who Can Legally Do the Work in New Zealand
Dropping a plug-in LED lamp into an existing GU10 fitting is a simple bulb change anyone can do. Replacing the fitting itself, moving a downlight, or touching the fixed wiring is a different matter. Under WorkSafe’s rules, an owner-occupier who lives in the home may legally replace a like-for-like light fitting themselves, provided no work touches the switchboard. New or altered wiring is where the rules tighten. WorkSafe says a homeowner who installs or alters cables must not connect the work to the supply: a licensed electrical inspector has to check, test and connect it and issue a certificate of compliance. Most people hand the whole job to an electrician at that point, who works to AS/NZS 3000 (the Wiring Rules).
For a rental you don’t live in, or any job someone is paid to do, a registered electrician is required regardless. Whatever the job, the electrician must issue an electrical safety certificate once the work is complete and safe (Electricity (Safety) Regulations 2010, reg 74A). A certificate of compliance is required for general and high-risk electrical work and optional for low-risk work (reg 65), so ask which one your job will come with. If a job turns out to be bigger than a downlight refresh and needs the circuit reworked, that moves into full rewiring territory. The electricians in our Auckland electrical maintenance network can tell you which side of that line your job sits on before any work starts.
Compliance note: WorkSafe says landlords and tenants can’t do electrical work in a rented property unless they are registered electrical workers with current practising licences. Owner-occupiers may do only the limited list WorkSafe publishes, and never switchboard work beyond fuses. For anything else, use a registered electrician and keep the certificate you’re given.
Getting Your Downlights Swapped in One Visit
The cheapest way to do this is all at once. Count the downlights, note which are GU10 and which run off a transformer, check your dimmers, and get one per-light price that includes the call-out. That turns a string of small call-outs into a single visit.

How much does it cost to replace a downlight with LED in NZ?
On our published guide range, replacing downlights with LED costs $70–$110 per light installed on a small job of two to five lights, including the fitting and electrician labour. For 10 or more lights in one visit, the per-light cost drops to $39–$70. The total depends on the fitting quality, number of lights, and whether any additional wiring work is needed. For anything beyond a like-for-like swap, use a registered electrician.
How much does a whole-house LED upgrade cost in Auckland?
A full LED upgrade for a typical Auckland home with 20–30 downlights costs between $900 and $2,100 installed. The per-light cost is lower for larger jobs because the electrician's callout fee is spread across more units. On EECA's figures, each LED that replaces an older bulb can save $100 to $300 in running costs over its life.
How much electricity do LED downlights save compared to halogen?
EECA says LED bulbs use up to 85% less electricity than traditional incandescent or halogen bulbs. Over its life, each bulb you replace with an LED can save $100 to $300 in running costs, depending on the wattage it replaces. Your own saving depends on how long the lights are on each day and the unit rate on your power bill, so check both before relying on the top of that range.
Can I replace halogen downlights with LED myself?
You can drop a compatible LED lamp into an existing GU10 fitting yourself. Under WorkSafe rules an owner-occupier may also replace a like-for-like fitting, as long as no switchboard work is involved. New or altered wiring is different: a licensed electrical inspector must check, test and connect it. In a rental, landlords and tenants can't do electrical work unless they are registered and licensed, so use a registered electrician.
How long do LED downlights last?
EECA gives a lifetime of around 30,000 hours for LED lights, against about 2,000 hours for an incandescent bulb, and says LEDs last up to 10 to 20 times longer. Rated life and warranty vary between fittings, so check both on the spec sheet before you buy. A longer-life fitting matters most in high ceilings and stairwells, where every replacement means a ladder.
Do LED downlights affect ceiling insulation?
Older halogen downlights usually need gaps in the ceiling insulation around them because of the heat they give off, and heat escapes through those gaps. EECA says most LEDs can be installed without gaps between them and the insulation, so replacing the fittings lets the gaps be closed. For a rental, check the insulation standard on tenancy.govt.nz and ask your installer whether the gaps need attention.
What colour temperature should I choose for LED downlights?
EECA's guidance is that warm white is more comfortable in homes and cool white works best where contrast matters, such as a workshop or garage. On the packaging, warm white is usually around 3000K and cool white around 4000K. Some LED fittings offer selectable colour temperature for flexibility. Avoid 5000K+ for residential spaces as it feels too clinical.
Are LED downlights compatible with dimmer switches?
Not all LED downlights work with existing dimmer switches. Incompatible combinations cause flickering, buzzing, or limited dimming range. When upgrading to LED, ask your electrician to check dimmer compatibility. Older leading-edge dimmers often need replacing with LED-compatible trailing-edge dimmers. Your electrician can price any dimmer that needs replacing in the same visit.
