This article is brought to you by TLC — Maryland’s trusted outdoor lighting team for energy-efficient upgrades, smart outdoor design, and long-lasting performance.
If your outdoor lighting still runs on halogen, it might be costing you more than you think.
In 2026, LED lighting isn’t just the future — it’s the now. And at TLC, we help Maryland homeowners replace outdated halogen systems with high-performance LED that looks better, lasts longer, and saves money every season.
So how much does it really cost to switch?
Let’s break it down.
Why LED Replacements Make Sense in 2026
- Lower energy use: Up to 80% less than halogen
- Cooler operation: Reduces fixture wear and heat stress
- Longer life: 30,000–50,000 hours vs 2,000–5,000 for halogen
- Less maintenance: No frequent bulb swaps or burned-out lamps
- Better brightness control: Dimmable, focused, color-tuned options
- Compatible with smart systems: Seamlessly works with apps, timers, and voice assistants
And here’s the big one:
LED saves money and stress over time.
Most people don’t realize that halogen systems rack up energy costs and maintenance calls that add up fast.
Average Cost to Convert Halogen to LED (2026)
| Conversion Scope | Typical Price Range |
| Simple bulb swap (if LED compatible) | $25 – $45 per fixture |
| Retrofit with new LED module | $75 – $150 per fixture |
| Replace fixture entirely (LED upgrade) | $200 – $350 per fixture |
| Add new transformer or smart control | $350 – $900 |
| Full system conversion (10–20 fixtures) | $2,000 – $6,500 |
Some TLC customers start with a few high-traffic areas (walkways, patio), then upgrade the rest in phases.
We often say:
“Start with where you live most. Then grow the system around your lifestyle.”
What Affects the Cost?
1. Fixture condition
If the housing is in good shape and compatible, we can often retrofit the lamp and socket. But if it’s corroded or sealed for halogen only, we usually replace the whole fixture.
2. Wiring quality
Older low-voltage systems may not be sized for modern LED loads. We check for splices, wire gauge, and insulation wear before finalizing your quote.
3. Transformer swap
Most halogen transformers were oversized or under-regulated. LED needs clean, consistent power. We’ll often upgrade the transformer for safety and longevity.
4. Layout changes
Many halogen systems were spaced for broader beams. LED can be more precise. So we sometimes move or re-angle fixtures during the upgrade.
5. Control system
Adding dimming, smart control, or zone-based lighting adds cost — but it gives you complete flexibility for ambiance.
Real TLC Case Study: Patio Upgrade in Severna Park
A couple had 14 halogen path lights and 6 uplights from a system installed in 2009. The lights were hot, constantly burning out, and their patio transformer buzzed.
TLC Solution: – Replaced all 20 fixtures with solid brass LED models – Upgraded transformer to a 300W smart-ready unit – Added timer and Bluetooth control module – Re-spaced uplights for new landscaping layout
Total cost: $4,900 Result: 80% energy reduction, gorgeous color tone, no heat near plantings, and no bulb replacements in 2+ years.
“It just works. And it looks ten times better than our old lights.”
Real TLC Case Study: Front Entry Restoration in Annapolis
This homeowner had inherited a halogen system from the prior owner. Four path lights were cracked, and one shorted during rain. TLC evaluated the system.
What we found: – Transformer had no surge protection – Wiring was frayed at two splices – Lights used 35W halogen — way too much for a 6-fixture system
Our fix: – Replaced all path fixtures with LED (2.5W per fixture) – Rewired all splices with direct-burial connections – Installed a compact transformer with surge and Wi-Fi control
Cost: $2,600 Outcome: Entry looks incredible, and the owner can dim lights from their phone before guests arrive.
Smart Lighting Upgrades with LED
More homeowners ask us about smart systems every year. LED integrates perfectly with: – Wi-Fi app-based controllers (schedule, scenes, timers) – Voice assistant integration (Alexa, Google) – Dimming modules for zones (patio vs path vs trees) – Holiday scene customization (warm white to festive tones)
We often recommend smart control when you’re: – Upgrading 10+ fixtures – Hosting outdoor events – Managing a property remotely (Airbnb, vacation home)
LED vs Halogen Energy Savings Breakdown
| Fixture Count | Halogen (50W ea) | LED (5W ea) | Annual Savings* |
| 10 fixtures | 500W | 50W | $250+ |
| 20 fixtures | 1,000W | 100W | $500+ |
*Assumes nightly 5-hour use for 8 months/year @ $0.12 per kWh
Plus, no more mid-season burnout calls. That’s worth something too.

FAQs About LED Conversion
Q: Can I keep my existing fixtures?
A: Maybe. If they’re in good shape and compatible, yes. If not, we’ll recommend LED-specific fixtures.
Q: Will it change the look of my yard?
A: Yes — for the better. LED offers cleaner color and more consistent coverage. We aim for a natural, welcoming tone.
Q: Is LED safe for pets and kids?
A: Absolutely. Fixtures stay cool to the touch and run on low-voltage power.
Q: Can I upgrade in stages?
A: Definitely. Start with the areas you use most. We can design systems that grow with you.
Q: What’s the lifespan of LED?
A: Most fixtures are rated 30,000–50,000 hours. That’s 10–20 years for most homeowners.
Q: Will I need maintenance?
A: Very little. We offer yearly system checks, but LED systems need far less attention than halogen.
