If your outdoor lighting system was installed more than eight or ten years ago, there is a good chance it runs on halogen bulbs. Halogen was the standard for residential landscape lighting for a long time, and it did the job well enough. The light looked warm. The fixtures were widely available. Installers knew how to work with them.
But LED technology has come a long way since those early days when the light looked cold and artificial. Today, LED landscape lights match the warm glow of halogen while outperforming it in almost every measurable way.
If you are building a new system or thinking about upgrading an older one, here is why LED is the clear choice in 2026.
Energy Use: LED Wins by a Wide Margin
Halogen bulbs convert a lot of their energy into heat instead of light. A typical 35-watt halogen spotlight puts out roughly the same amount of usable light as a 5 to 8 watt LED. That means the halogen bulb uses four to six times more electricity to produce the same result.
On a single fixture, the difference in your electric bill is small. But most landscape lighting systems have 15 to 30 fixtures or more. Multiply that energy gap across every fixture running four to six hours a night, every night of the year, and the savings add up quickly.
Homeowners who switch from halogen to LED on an existing system often see a noticeable drop in their electricity costs within the first billing cycle.
Bulb Life: Years vs. Months
A halogen bulb lasts roughly 2,000 to 4,000 hours. If your system runs five hours a night, that means you are replacing bulbs every one to two years. Some burn out sooner, especially in fixtures that trap heat or get hit with moisture.
LED fixtures are rated for 40,000 to 50,000 hours or more. At the same five hours per night, that is over 20 years before the light output starts to diminish. And even then, LEDs do not burn out the way halogen bulbs do. They gradually dim over a very long period rather than failing all at once.
This means fewer service calls, fewer trips to the store for replacement bulbs, and fewer evenings spent noticing that half the lights in your yard are dark.
Heat Output: Cooler Is Safer
Halogen bulbs run hot. Very hot. A 50-watt halogen spotlight can reach surface temperatures above 400 degrees Fahrenheit. That kind of heat is a real concern when fixtures sit close to mulch, dry leaves, plant foliage, or wood decking.
LED fixtures run cool to the touch by comparison. This makes them safer around landscaping materials and eliminates the risk of scorching plants that grow close to a fixture over time.
It also means LED fixtures are more comfortable to adjust by hand if you need to reposition one. Try that with a halogen light that has been on for an hour and you will learn that lesson the hard way.
Light Quality: LED Has Caught Up
The early knock on LED was that the light looked cold, bluish, and artificial. That was true ten or fifteen years ago. Early residential LEDs were designed for efficiency first and appearance second, and the result was a sterile look that did not work well in landscape applications.
That is no longer the case. Modern LED landscape fixtures are available in warm color temperatures (2700K to 3000K) that look virtually identical to halogen. Most homeowners cannot tell the difference once the fixtures are installed and aimed.
In fact, LED offers something halogen never could: consistency. Every LED fixture in a product line produces the same color temperature. Halogen bulbs can vary slightly from bulb to bulb, and that variation becomes more noticeable as bulbs age and their color shifts.
Transformer Load: More Fixtures, Less Strain
Because LED fixtures draw so much less power than halogen, your transformer has more capacity to work with. A transformer that maxes out at 15 halogen fixtures might comfortably handle 40 or more LED fixtures.
This matters if you want to expand your system later. With halogen, adding a few lights to the backyard might mean upgrading your transformer or adding a second one. With LED, you often have plenty of headroom on the existing transformer to add lights without any electrical changes.
It also means less voltage drop across long wire runs. Lower wattage fixtures put less strain on the wiring, so the lights at the far end of a run stay bright instead of dimming.
Durability in Indiana Weather
Indiana puts outdoor fixtures through a cycle of extremes every year. Summer heat and humidity, fall rain, winter freeze and thaw, spring storms. That cycle repeats and takes a toll on anything sitting in your yard.
Halogen bulbs are more sensitive to moisture and vibration. A heavy storm can sometimes knock out a bulb that was already near the end of its life. And the heat cycling (hot when on, cold when off, hot again the next night) shortens their lifespan faster in climates with big temperature swings.
LED fixtures handle temperature fluctuations better because they do not generate the same internal heat stress. High quality LED fixtures paired with sealed, corrosion resistant housings hold up to Indiana conditions for years without degradation.
This is one of the reasons every fixture Serenity Outdoor Lighting installs comes with a lifetime manufacturer’s warranty. The products are built to handle what our climate throws at them.
How to Switch From Halogen to LED
If you already have a halogen landscape lighting system and want to upgrade, the process is simpler than most people expect.
Option 1: Retrofit With LED Bulbs
Some older halogen fixtures accept LED retrofit bulbs that fit the same socket. You pull out the old halogen bulb and drop in an LED replacement. This is the fastest and least expensive option.
The trade-off is that you are still using the old fixture housing, which may be showing wear after years outside. And not every halogen fixture accepts a retrofit bulb cleanly. Sometimes the beam angle or light output is slightly different, which can change the look of your design.
Option 2: Replace the Full Fixtures
This is the better long term option. Replacing the fixtures entirely means you get modern LED technology, fresh housings that are sealed and weather ready, and a clean starting point for the next 15 to 20 years.
It is also a good opportunity to revisit your overall design. If your original system was installed years ago, your landscaping has probably changed. Trees are taller. Shrubs have filled in. Maybe you added a patio or a water feature that was not there before. A full fixture upgrade lets you redesign the lighting plan to match your property as it looks today.
What About the Transformer?
In most cases, your existing transformer can stay. Since LED fixtures draw less power, your current transformer will likely have more than enough capacity. A professional installer will test the transformer output and confirm whether it works with the new fixtures before starting the job.
If the transformer is very old or undersized, replacing it is straightforward and not a major cost.
The Cost Comparison Over Time
LED fixtures cost a bit more upfront than halogen equivalents. But when you factor in energy savings, bulb replacement costs, and service calls over a five to ten year period, LED comes out significantly cheaper.
Think about it this way. With halogen, you pay less for the initial bulbs but keep paying for replacements, higher electric bills, and occasional service visits when bulbs burn out in hard to reach fixtures. With LED, you pay a bit more once and then spend almost nothing on maintenance for years.
For new landscape lighting installations, there is really no reason to consider halogen at this point. LED is the standard for professional systems, and every reputable lighting company has made the switch.
