Austin is one of a growing number of Texas cities that has adopted outdoor lighting regulations designed to reduce light pollution and preserve the night sky. If you’re planning a landscape lighting project in Austin, understanding these regulations — and how to design lighting that complies with them — is important. Here’s what you need to know.
What is the Austin Dark Sky Ordinance?
Austin’s outdoor lighting regulations are designed to minimize light trespass (light that spills onto neighboring properties), reduce glare, and limit sky glow — the orange haze of upward-scattered light that obscures stars above urban areas. The ordinance applies primarily to commercial properties and new construction, but its principles guide best practices for all outdoor lighting in the city.
What Does “Dark Sky Friendly” Lighting Mean?
Dark sky compliant lighting has three key characteristics: it is fully shielded (directing light downward, not upward or sideways), it uses warm color temperatures (typically 3000K or lower), and it uses the minimum light level needed for the task. Ironically, dark-sky principles align almost perfectly with good landscape lighting design — fixtures that direct light precisely where it’s needed look better and waste less energy.
Choosing the Right Fixtures
Full-cutoff fixtures — those with optics that direct all light below the horizontal plane — are the standard for dark-sky compliance. In practice, this means fixtures with solid tops and optics that focus the light downward. Most quality landscape lighting fixtures already meet this standard by design.
Color Temperature Matters
High color temperature LEDs (4000K–6500K, the “cool white” or “daylight” spectrum) contribute more to sky glow than warm LEDs. The Austin area and the broader Hill Country ecosystem benefit from warm amber lighting (2200K–2700K), which is also less disruptive to native wildlife.
Good Lighting is Dark Sky Lighting
At Majestic Outdoor Lighting Design, every system we install uses fully shielded, warm-spectrum fixtures aimed precisely where they’re needed. Our approach naturally aligns with dark sky principles — because good lighting design has always been about putting light exactly where you want it and nowhere else. Call 281-570-7552 to learn more.
