Coastal Source vs. Kichler vs. VOLT: Which Landscape Lighting Brand Lasts in Charleston's Salt Air?

If you live in Charleston, Mount Pleasant, Isle of Palms, or Kiawah Island, the fixture brand you choose for your landscape lighting system matters more than anywhere else in the country. Salt air, humidity, and frequent coastal storms accelerate corrosion at a rate that simply isn't a factor in landlocked markets.

We get asked constantly: "Can't I just use the Kichler fixtures from the big box store?" Here's an honest, side-by-side answer.

The Core Problem: Coastal Corrosion

Standard landscape lighting fixtures — including most brands sold at hardware stores and through general landscape contractors — are made from cast brass, zinc-alloy, or powder-coated aluminum that's not rated for coastal exposure. In a market like Charlotte or Atlanta, these fixtures perform fine for 5–10 years. In Charleston:

• Salt air attacks zinc-alloy castings within 12–18 months
• Moisture penetrates non-sealed connectors, corroding connections and causing flicker
• UV exposure in the Lowcountry degrades plastic lenses and seals faster than northern climates
• Flooding from storms infiltrates fixtures not rated for submersion

The result: homeowners who went with a budget installer 3 years ago are now replacing the entire system.

Brand-by-Brand Breakdown

Coastal Source ⭐⭐⭐⭐⭐

The only fixture brand engineered specifically for coastal environments.

• Marine-grade 6063 aluminum housing — the same alloy used in marine hardware
• Powder-coat finish tested to 1,000+ hours salt-spray exposure (ASTM B117)
• IP68-rated connectors — fully submersible, no moisture ingress
• Patented Plug+Play™ system — snap-together connections that never corrode
• Lifetime warranty — no questions asked, ever

Coastal Source was founded specifically because the owners watched standard fixtures fail in coastal Florida installations. It's the brand chosen by professionals who work in salt-air environments every day — and it's the only brand Halo installs.

Kichler ⭐⭐⭐

Good for inland markets. Not ideal for coastal Charleston.

Kichler is one of the most recognized landscape lighting brands in the country, and their fixtures are well-made for normal climates. However:

• Standard Kichler fixtures are cast brass or zinc-alloy — not marine-grade
• Connector systems are not IP68-rated
• No warranty covers salt-air corrosion damage
• Fixtures typically last 3–7 years in coastal South Carolina environments

Kichler does offer some "Coastal" SKUs, but these are still not purpose-built for barrier island exposure the way Coastal Source is.

VOLT Lighting ⭐⭐⭐

Good value, honest company. Still not coastal-grade.

VOLT has built a strong reputation in the DIY and professional market for value-priced brass fixtures. Their brass construction is better than zinc for coastal applications, but:

• Not rated to the same salt-spray standards as Coastal Source
• Connector systems are traditional, not sealed
• Good choice inland; not what we'd recommend on Isle of Palms or Kiawah

Generic / Big Box Brands ⭐

Avoid for Charleston properties.

Home Depot and Lowes carry landscape lighting that will corrode within 1–2 seasons in coastal Charleston. The price is low; the total cost of ownership is high.

The Bottom Line for Charleston Homeowners

If your property is within 20 miles of the coast — which includes all of Charleston County — you should specify Coastal Source or be prepared to replace your system on a 3–5 year cycle. The lifetime warranty alone makes Coastal Source the lower total cost option over a 10-year horizon.
