delivered turnkey.

The most reliable, solid, cost-effective, and efficient way to solar-light your project, engineered by the manufacturer, not a reseller.

25-Year Service Life

Stealth II systems are engineered for a 25-year design life, with simple battery replacement every 5–7 years.

LiFePO4 Batteries

Long-life, replaceable lithium batteries deliver 7–10 years of quality operation, sized for dusk-to-dawn autonomy.

Dark Sky Compliant

An adjustable LED bar and light shields let you angle output precisely, putting the light exactly where it belongs.

Turnkey, No Wiring

A single complete unit that requires no wiring, fast and easy to install on almost any street-light pole.

The Fixture

The Stealth II
all-in-one portfolio.

Solar Lighting International, Inc. is excited to introduce our NEW “Stealth II” All-In-One Solar Light Portfolio. All-in-one solar street lights integrate a monocrystalline solar panel, Philips 5050 LED chips, and a long-life LiFePO4 battery into a compact, reliable, and extremely bright package.

This solar all-in-one street light and parking-lot light is an alternative to traditional solar lighting system design. We provide a single, complete unit that requires no wiring, making this product fast and easy to install. When your lighting project must succeed, you want to select the Stealth II all-in-one solar light.

The Manufacturer

Programmable,
and proven in the field.

SLI’s all-in-one solar street, parking-lot, and roadway light provides multiple programming options: standard dusk-to-dawn without dimming, adjustable timed control mode, and motion-activated human-body sensor mode via our dual-sensor technology. Time-control mode includes an all-night sensor mode and a morning mode: one simple setup and the controller adjusts each mode automatically.

The Stealth II is manufactured for a 25-year life design with battery replacement every 5–7 years. The Philips-illuminated LED light bars are TM-21 heat-tested to 80°C and last over 60,000 hours, verified by 3rd-party Energy-Star-rated testing. It has performed in the harshest cold, reaching −22°F at an installation in Helena, Montana. Hot or cold, saltwater or extreme weather, the Stealth II remains the most reliable solar light available.

How It Works

You have questions.
We have answers.

The Stealth II Solar Lighting System is designed with a compact, high-efficiency monocrystalline solar panel, an MPPT (Maximum Power Point Tracking) charge controller, greater than 190 lumens-per-watt LED light bars, a long-life LiFePO4 battery, a 15-meter (50-foot) PIR motion sensor, an optional IoT 4G/5G smart-city software package, and more.

Why monocrystalline?

A monocrystalline module produces more energy, works better in high temperatures and low-light areas, and lasts longer than polycrystalline panels: a budget-friendly panel that’s built to last.

What is >190 lm/W?

It means we produce more light using less power than our competitors. Watts don’t matter; lumens do. The higher the lumen-per-watt ratio, the brighter and more efficient the system you can expect.

Adjustable LED bar?

Yes. Competitors use a fixed, non-adjustable bar: an outdated, inefficient design. Our LED bar adjusts 40 degrees in each direction, so you can put the light exactly where you need it.

How long does the battery last?

LiFePO4 is a long-lasting, replaceable battery. Expect 7–10 years of quality operation from the cells, and up to a 25-year service life from the overall solar lighting product line.

How does it mount?

It fits almost any street-light pole that reduces to 2⅔″ (60mm). SLI can supply fiberglass, aluminum, or steel pole options, or you can provide your own.

Color options?

We took the Henry Ford Model T approach: you can have any color you want, as long as it’s black. And by investing in solar, the U.S. government may incentivize your commercial purchase. We email the forms with every invoice.
