Your outdoor lights have been flickering for weeks, or maybe your transformer is tripping every time it rains. You’re finally ready to deal with it and now you’re staring at a choice between LED and halogen. Here’s what that decision actually looks like in practice, from someone who’s swapped out hundreds of fixtures across Albuquerque properties.
Why halogen keeps showing up in older systems
Halogen fixtures dominated residential landscape lighting for decades, and you’ll still find them on most homes built before 2015. The warm amber glow is familiar and genuinely attractive. Cost upfront is lower a halogen MR16 runs about $3 to $5, and the fixtures themselves are cheaper to buy and install.
The catch: halogen bulbs in New Mexico’s climate cycle burn out fast. We see a lot of 50-watt halogens in Albuquerque dying inside six months because of temperature swings it can be 28°F at night in January and 95°F by July afternoon. That thermal stress shortens filament life significantly. By the time you’ve replaced those bulbs two or three times a year, the “cheaper” option isn’t cheap anymore.
What LED actually costs over time
A quality LED MR16 replacement costs around $8 to $14 and lasts 25,000 hours or more roughly 12 to 15 years of typical residential use. A halogen of the same wattage equivalent is lucky to hit 2,000 hours. I’ve seen homeowners over in the North Valley spend more on halogen replacements in two years than a full LED retrofit would have cost them upfront.
Power draw is the other number. A 50-watt halogen replaces with a 6- to 7-watt LED producing the same output. Run ten fixtures five hours a night and halogen is pulling about 750 watts; LED pulls around 65. That gap shows up on your bill every month more so if you’re running your system year-round, which most Albuquerque homeowners do thanks to mild winters and heavy entertaining seasons.
Color and appearance: the honest version
This is where halogen defenders have a real point. Halogen produces a continuous warm spectrum a natural, incandescent-adjacent glow that looks especially good on adobe, stucco, and desert landscaping. Early LEDs were a poor substitute: too blue, too harsh, too flat.
Modern LEDs have closed that gap substantially. A 2700K or 3000K LED is hard to distinguish from halogen in most applications. That said, color rendering still varies by brand and price point. We don’t spec the cheapest LED fixtures for this reason. On premium landscape fixtures in the 90+ CRI range, the difference is essentially undetectable. On budget fixtures, you’ll notice it under mature trees or against warm stone.
When to leave halogen alone
Not every halogen system is worth converting. If you have a smaller system say, four or six path lights on a 150-watt transformer and the fixtures are in good shape, the payback on a retrofit might stretch to seven or eight years. That’s not a compelling case.
Retrofit also has a technical limit. Some older magnetic transformers don’t play well with LED loads, particularly with very small LED wattages. Minimum load requirements can cause flickering or buzzing. An electronic (digital) transformer handles LED loads cleanly; a magnetic one might need to be replaced as part of the upgrade, which changes the math on your investment. We always check the transformer first before quoting a halogen-to-LED conversion.
Ready to stop replacing bulbs?
Red Shovel Landscaping handles full LED retrofits and new installations across the Albuquerque area. If your halogen system is eating bulbs or you’re ready to design something new, give us a call before you start buying fixtures a lot of DIY installs end up with the wrong transformer, mismatched color temperatures, or wiring that won’t pass a home inspection. Getting it right the first time costs less than fixing it the second.
FAQs
Can I just swap my halogen bulbs for LED bulbs in the same fixtures?
In most cases, yes MR16 and G4 LED replacements drop into the same sockets. The real question is whether your transformer will handle the lower wattage load. Some older magnetic transformers require a minimum load to function correctly, and LED wattages can fall below that threshold. We usually do a quick transformer check before swapping anything.
How much can I actually save switching from halogen to LED in Albuquerque?
It depends on system size and run time, but a 10-fixture system running five hours a night in Albuquerque typically saves $15 to $30 per month after switching. That adds up to $180 to $360 per year, and you’re also not climbing around the yard replacing bulbs twice a year.
Do LED landscape lights work in the desert heat?
They handle our climate better than halogen does. Heat degrades halogen filaments faster than almost anything else we see a lot of early burnout on south-facing fixtures during Albuquerque summers. LEDs are more tolerant of sustained heat and handle the freeze-thaw cycling better too.
Is there a permit required for landscape lighting installation?
Low-voltage systems (12V, which covers most landscape lighting) don’t require a permit in Albuquerque. Line-voltage work 120V fixtures, dedicated circuits does require a licensed electrician and permit. If someone is quoting you line-voltage landscape lighting without mentioning permits, ask about it.
What color temperature should I use for my landscape lights?
For most Albuquerque homes particularly adobe, stucco, or Southwest-style exteriors 2700K or 3000K is the right range. It’s warm, flattering on natural materials, and close to what halogen produces. Anything above 4000K starts to look clinical outdoors and tends to wash out warm-toned landscaping.
