Landscape Lighting Guide: LED vs. Halogen for Illinois Outdoor Spaces
Jul 15, 2026
Your Frankfort home looks beautiful during the day, but at night it disappears into darkness. You want landscape lighting to highlight architectural features, illuminate walkways for safety, and create curb appeal after sunset. But when you start researching, you’re hit with questions: LED or halogen? What wattage? And why do some contractors quote $3,000 while others quote $8,000?
Landscape lighting options in Illinois come with specific considerations our climate demands. Fixtures that perform beautifully in Arizona might fail after one Illinois winter. Energy costs with ComEd rates make efficiency calculations different than other regions. This guide breaks down what actually works in southwest Chicago suburbs.
LED vs. Halogen: The Fundamental Differences
Halogen landscape lights use traditional tungsten filament technology that produces a warm 2700-3000K color naturally. These fixtures generate significant heat and typically last 2,000-4,000 hours—about 1-2 years with regular evening use. Most halogen fixtures consume 20-50 watts per fixture and cost less upfront than LED alternatives.
LED landscape lights use solid-state semiconductor technology that’s available in multiple color temperatures. They generate minimal heat and last 25,000-50,000+ hours, which translates to 11-22 years of typical use. LED fixtures consume just 3-12 watts per fixture but come with higher upfront costs.
The basic math makes the decision clear: LED fixtures cost 2-3 times more upfront but use 75-85% less electricity and last 10-15 times longer. Over the fixture’s life, LED is dramatically cheaper despite the higher initial investment.

Energy Cost Comparison: Real Numbers for Illinois
Let’s get specific with ComEd’s 2026 residential rates, which run approximately $0.13-0.15 per kilowatt-hour depending on season and usage patterns. For a typical system of 20 fixtures running 6 hours nightly, the numbers tell a compelling story.
A halogen system with 20 fixtures at 35 watts each costs $204-230 annually in electricity, adding up to $2,040-2,300 over ten years. An equivalent LED system with 20 fixtures at 7 watts each costs just $41-46 annually, totaling $410-460 over the same decade. That’s a ten-year savings of $1,630-1,840 in electricity costs alone—and that doesn’t include the cost of replacing 100-200 halogen bulbs during that period.
For larger systems common in Homer Glen and Orland Park properties with 30-40 fixtures, savings exceed $2,500-3,000 over ten years. Even if LED fixtures cost $1,000 more upfront, you’re ahead financially within 5-7 years while avoiding the hassle of repeated bulb replacements.
Color Temperature and Long-Term Maintenance
Color temperature significantly affects how your landscape looks at night. Warm white in the 2700-3000K range works best for most Illinois landscapes, complementing the brick and stone homes common throughout the southwest suburbs while creating an inviting, cozy atmosphere. Neutral white (3500-4000K) can work for modern architecture but sometimes feels institutional. Cool white (5000K and above) is too harsh for most residential applications—reserve it exclusively for security lighting where maximum visibility trumps aesthetics.
The maintenance comparison over ten years reveals the true cost difference between technologies. A halogen system with 20 fixtures requires replacing each bulb 5-10 times over the decade, totaling 100-200 bulb replacements. The cost runs $500-3,000 just in bulbs, plus the labor time for all those replacements. An LED system with 20 fixtures likely needs zero replacements in the first ten years, with possibly 1-2 driver failures if you choose cheaper fixtures. Your maintenance cost stays between $0-200, and you’re not spending weekend afternoons changing landscape light bulbs.

Application-Specific Recommendations
Path lighting performs best with LED technology. These fixtures run all evening, every evening—exactly where LED efficiency delivers maximum value. Use 3-5 watt LED fixtures spaced 8-10 feet apart in the 2700-3000K range for warm, inviting illumination that guides safely without overlighting.
Accent lighting for trees, architecture, and features also favors LED in most situations. The long life matters enormously since many accent fixtures are difficult to access once installed—think fixtures mounted high on walls or positioned in tree canopies. Use 7-12 watt LED fixtures for most accent applications, adjusting wattage based on the size of what you’re illuminating.
Security lighting absolutely demands LED technology. The instant-on characteristic means full brightness immediately with no warm-up period—critical for safety applications and motion-sensor triggers. Use 10-15 watt LED fixtures, and consider 4000K color temperature for maximum visibility if you don’t mind the slightly cooler appearance.
Deck and patio lighting runs many hours during entertaining season, making LED efficiency particularly valuable. The low heat output also creates a safer environment than hot halogen fixtures that can burn skin if accidentally touched. Use 1-3 watt LEDs for recessed deck lights and 3-5 watts for post cap fixtures.
Low-Voltage Systems and Installation
Most residential landscape lighting in Illinois uses 12-volt or 24-volt low-voltage systems rather than 120-volt line voltage. These systems are safer, more flexible, and easier to modify or expand over time.
Transformer sizing requires careful calculation. Add up the total wattage of all fixtures, then multiply by 1.25 to account for voltage drop over wire runs. For example, 20 fixtures at 7 watts each equals 140 watts. Multiply by 1.25 and you get 175 watts minimum transformer capacity. Choose a 200-300 watt transformer to leave room for future expansion without replacing the transformer.
Wire gauge matters more than most homeowners realize. Use 12-gauge wire minimum for any run exceeding 50 feet. For runs over 100 feet, step up to 10-gauge wire. Undersized wire causes voltage drop, which means fixtures at the end of long runs will be noticeably dimmer than those near the transformer—a common problem in DIY installations using whatever wire was cheapest at the hardware store.
Lighting Ordinances: Local Requirements
Before installing landscape lighting, understand local regulations in your municipality. Both Orland Park and New Lenox have ordinances stating that outdoor lighting shouldn’t create nuisance to neighbors. Fixtures must be shielded or directed to prevent glare onto adjacent properties.
Best practices that comply with ordinances and maintain good neighbor relations include directing fixtures downward when near property lines, using fixtures with built-in shielding to control light direction, and avoiding uplighting trees near boundaries where light could shine into neighbor’s windows. If you live in a planned community in Homer Glen, Mokena, or Frankfort, check your HOA covenants before installation—many communities require architectural review board approval for exterior lighting.
Cost Expectations for 2026
Understanding realistic pricing helps you evaluate contractor proposals fairly. For a professionally installed LED system with 20 fixtures, expect budget quality installations to run $2,500-4,000, mid-range systems to cost $4,000-6,500, and premium installations with high-end fixtures to range from $6,500 to over $10,000.
What affects these price differences? Fixture quality varies dramatically between brass construction and composite materials, and between commercial-grade components and residential-grade ones. Wire burial method matters too—surface installations cost less than properly trenched systems. Transformer quality, design complexity, and site accessibility all influence final pricing.
Watch for red flags in proposals. Pricing that’s 30% or more below competitors usually means cheap fixtures that won’t last. Proposals lacking fixture specifications or brand names suggest the contractor is cutting corners. Missing warranty information, undersized transformers, or no voltage drop calculations on larger systems all indicate problematic installations that will cause headaches later.
