When people think about adding garden lighting, one of the questions that often comes up is: Will this increase my power bill?
The good news is that with today’s hardwired LED systems, the impact on your energy costs is surprisingly minimal. Unlike the old halogen fittings that chewed through electricity, modern LED garden lights are designed to be efficient, durable, and cost-effective, all while transforming your outdoor space.
Here’s what you need to know about the real costs of running garden lights.
Why LED Has Replaced Halogen
Not long ago, outdoor lighting relied heavily on halogen fittings. While halogen bulbs delivered plenty of light, they were notorious for being inefficient and short-lived. In fact, halogens convert a large portion of electricity into heat rather than light, making them wasteful and costly to run.
By comparison, LED (Light Emitting Diode) technology offers:
- Up to 80–90% less energy consumption than halogen equivalents
- Cool operation (no wasted energy as heat)
- Long lifespan, often 25,000–50,000 hours or more, 10 to 20 x the life of halogens
- Durability in outdoor environments
This means that switching to LED isn’t just about saving power; it’s about reducing maintenance, replacements, and environmental impact at the same time.
The Real Cost of Running Garden Lights
So, what does this look like on a household power bill?
Let’s break it down:
- A single 5-watt LED garden light uses only 0.005 kWh of electricity per hour.
- If you run 10 of these lights for 5 hours every night, that’s 0.25 kWh per day, or about 7.5 kWh per month.
In other words, you could run a modest garden lighting system every evening of the year for less than $30 annually about the cost of a single dinner out.
By contrast, the same setup with halogen fittings could easily cost 5–10 times more.
Smarter Controls = Even Lower Costs
Another major advantage of hardwired systems is how they can be paired with timers, sensors, and smart technology. These controls ensure you only use lighting when and where it’s needed, cutting down waste even further.
- Timers: Set your system to turn on at dusk and off at a fixed time each night.
- Motion sensors: Add extra security lighting that only activates when movement is detected.
- Dusk-to-dawn sensors: Automatically adjust with the seasons for seamless operation.
- Smart controls: Integrate with apps or home automation for remote access and scheduling.
The result? You get the beauty and security of a well-lit property without worrying about unnecessary energy use.
Long-Term Value: Durability and Performance
While upfront investment in hardwired lighting is higher than solar or DIY options, the long-term cost benefits are undeniable.
- Quality LEDs designed for outdoor fittings, last longer, reducing the need for replacements.
- Durable fittings, NZ-made fixtures are built for harsh climates, from heavy rain to coastal salt air.
- Consistent brightness, unlike solar, which fades after cloudy days or limited sun exposure.
- Warranty-backed performance , The Garden Lighting Company offers a 10-year “3520 Nights of Light” guarantee for complete peace of mind.
Instead of constantly replacing fittings, bulbs, or batteries, you get years of reliable, energy-efficient performance.
The Environmental Advantage
For many homeowners, the sustainability aspect is just as important as the cost savings.
- Lower energy use reduces your carbon footprint.
- Fewer replacements mean less landfill waste.
- Cooler operation makes LEDs safer for plants and outdoor materials.
By choosing a professional hardwired LED system, you’re making an environmentally responsible choice without sacrificing performance or style.
Hardwired LED garden lighting doesn’t just keep your outdoor spaces beautiful and safe, it does so with minimal impact on your power bill. By pairing energy-efficient fittings with smart controls and durable NZ-made materials, you get a system that is sustainable, reliable, and cost-effective for years to come.

Garden Lighting & Power Bill FAQs
Do garden lights significantly increase power bills?
Not with LED systems. A well-designed hardwired LED setup uses very little energy, often adding just a few dollars per month to your bill, even with nightly use.
How do LED garden lights compare to halogen?
LEDs are up to 80–90% more efficient, last longer, and run cooler than halogen fittings — meaning lower running costs and less maintenance.
Can I control when my garden lights turn on?
Yes. Hardwired systems can integrate with timers, dusk-to-dawn sensors, or smart controls, ensuring lights only run when you need them.
What’s the long-term cost benefit of hardwired LED lighting?
Beyond the low running costs, LEDs have a much longer lifespan than halogens, reducing replacement expenses. Combined with warranties like The Garden Lighting Company’s 10-year “3520 Nights of Light” guarantee, the long-term ROI is strong.
Is outdoor LED lighting environmentally friendly?
Yes. LEDs consume less electricity, reducing your carbon footprint, and their long life means fewer fittings and bulbs need to be replaced over time.
