Low Voltage ET2 Landscape Lighting LED: What Changed in 2025

Landscape lighting has quietly undergone a real shift over the past two years. The old halogen fixtures that burned out every six months are gone, and the newer low voltage ET2 landscape lighting LED units run cooler, last longer, and throw a cleaner beam than anything from a few seasons ago. But the recent change is not just the bulb type—it is the housing, the color temperature, and the way these fixtures handle rain and frost. If you are replacing a tired system, here is what actually matters now.

Why the Switch to LED Changed the Whole Fixture

The move to LED landscape lighting did more than cut the electric bill. It changed how manufacturers build the sockets, lenses, and even the wire gauge inside each unit. Halogen bulbs produce intense heat, so older fixtures needed large metal bodies to dissipate it. LED chips run at a fraction of that temperature, which let designers shrink the housings and use sealed optics that keep water out far better.

That means a modern ET2 low voltage path light can be half the size of its halogen predecessor while putting out the same usable light. The trade-off is that you must pay attention to the driver and the transformer, because LED fixtures are pickier about voltage drop over long cable runs.

What Do the New ET2 LED Fixtures Cost?

A single ET2 LED landscape spotlight typically runs between 45 and 90 dollars. Path lights sit in the 60 to 110 dollar range, and a full bollard-style fixture can go up to 150 dollars. That price point is roughly 20 to 30 percent higher than the old halogen equivalents, but the LED chips inside are rated for 25,000 to 50,000 hours of use.

For a typical front yard with 12 to 15 fixtures, the total material cost lands between 700 and 1,300 dollars. That does not include the transformer or the low voltage cable, which adds roughly 150 to 250 dollars depending on the run length.

Sizing the Transformer for a Low Voltage Run

The transformer is the part most people get wrong. A low voltage ET2 landscape lighting LED system runs on 12 volts AC, but the cable resistance drops voltage over distance. If you run a 200-foot cable to a fixture rated at 12 watts, you can lose up to 1.5 volts before the power arrives. That dims the LED and shortens its life.

The practical rule is to keep the total wattage of all fixtures at 80 percent of the transformer rating. So a 300-watt transformer comfortably powers 240 watts of LED fixtures. Also, plan the cable layout in a loop rather than a single long line. A loop feeds power from both ends, which cuts voltage drop roughly in half.

Matching the Beam Angle to the Landscape Feature

The beam spread matters more than the wattage for the final look. A narrow 15-degree spot works for a tall tree trunk or a flagpole. A 36-degree flood is better for washing a brick wall or a low hedge. The newer ET2 fixtures come with interchangeable lenses, so you can buy one housing and swap the optic to match the planting bed.

For a typical two-story colonial home, you want:

• 4 to 6 narrow spots aimed at architectural columns
• 3 to 4 wide floods for the foundation shrubbery
• 6 to 8 path lights along the walkway, spaced 8 to 10 feet apart

Keeping the Fixtures Clean After a Wet Season

The sealed optics on modern ET2 landscape LED lights keep out rain, but they still collect dust and pollen on the lens face. That film cuts light output by up to 30 percent over a few months. Wipe the lenses with a microfiber cloth and a drop of dish soap in warm water twice a year.

Check the rubber gaskets around the bulb housing each spring. If the gasket looks cracked or flattened, replace it before the heavy rain season. A failed gasket lets moisture inside the housing, which corrodes the brass contacts and kills the LED driver.

How Do ET2 LED Units Handle Freezing Temperatures?

The LED chips themselves tolerate cold well, but the plastic lenses can become brittle below 20 degrees Fahrenheit. The current ET2 line uses a polycarbonate lens that holds up to about minus 10 degrees, which is a real improvement over the acrylic lenses from five years ago. If you live in a northern climate, check the product spec for the lens material before buying.

Also, the low voltage cable should be buried at least 6 inches deep. In freezing zones, go 8 to 10 inches to protect the insulation from frost heave, which can nick the jacket and cause a short.

Choosing Between Brass and Aluminum Housings

The housing metal determines how long the fixture survives outdoor exposure. Brass fixtures develop a natural patina and last 20 years or more, but they cost 30 to 40 percent more. Aluminum fixtures are cheaper and lighter, but the powder coat finish will chip if you hit them with a weed trimmer. Once the coating chips, the aluminum corrodes quickly.

For a seaside property with salt air, brass is the only sensible choice. For a protected backyard with no salt exposure, aluminum works fine. A brass ET2 landscape path light will hold its resale value better if you ever sell the house.

Wiring the Fixtures in a Radial Layout

A radial layout means running a main cable from the transformer to a central junction, then branching out to each fixture. This keeps each branch short, which reduces voltage drop. For a 12-fixture system, use 12-gauge wire for the main run and 14-gauge for the short branches to each light.

Use waterproof wire connectors rated for direct burial. The twist-on connectors from the hardware store are not sufficient—they let moisture creep into the splice. Use the gel-filled connectors that cost about a dollar each. That small expense prevents a frustrating failure in year two.

Replacing One Fixture Without Replacing the Whole System

If you already have an older low voltage system, you can often swap the old heads for new ET2 LED bulbs without changing the transformer or cable. Most ET2 fixtures use a standard GU5.3 base, which matches the older halogen sockets. The new LED bulbs fit right in, though you may need to replace the socket if the old one has corroded pins.

For a quick upgrade, look for a low voltage ET2 LED bulb that matches your existing fixture base. Check the lumen output against your old halogen bulb—a 12-watt LED puts out roughly the same light as a 20-watt halogen, so you can go down in wattage and still see the same brightness.

Adjusting the Aim for a Layered Night Scene

Aim the fixtures in layers. The first layer is the path lights, which guide the eye along the walkway. The second layer is the uplights on the house columns, which define the architecture. The third layer is the moonlighting effect—placing a fixture high in a tree and aiming it down to cast dappled shadows on the lawn.

Set the fixtures at a 30-degree angle from vertical for the most natural look. Straight up creates harsh shadows, while too flat an angle washes out the texture of the bark or brick. Spend an evening walking the yard with a helper moving the heads until the light feels balanced.

Checking the Color Temperature Before You Buy

The color temperature is measured in Kelvin, and it changes the entire mood of the yard. 2700K gives a warm amber glow that matches old incandescent bulbs. 3000K is a slightly crisper white that still feels warm. 4000K looks clinical and blue, and it makes a residential yard feel like a parking lot.

Most ET2 landscape fixtures ship with a 2700K chip, which is the safe choice for a home. If you want a slightly more modern feel, the ET2 LED landscape lighting kit with 3000K chips is a good middle ground. Avoid the 4000K option unless you are lighting a commercial storefront.

Planning the Layout for a Narrow Side Yard

A narrow side yard, about 4 to 5 feet wide, needs a different approach than a front lawn. Use small well lights recessed into the ground rather than path lights that stick up and crowd the walkway. Space them 5 to 6 feet apart, aiming straight up to wash the fence line.

For a long driveway, place ET2 LED bollard lights every 15 feet along one side. That spacing keeps the driveway edge visible without creating a runway effect. The bollards should be 36 inches tall to match the sightline of a driver backing out of a garage.
