Title 24 Outdoor Lighting Requirements 2019

Essential Aspects of Title 24 Outdoor Lighting Requirements 2019

Title 24 Outdoor Lighting Requirements 2019 are a set of regulations adopted by the California Energy Commission to reduce energy consumption and light pollution from outdoor lighting fixtures. These requirements are designed to help homeowners, businesses, and municipalities save energy and reduce the negative impacts of light pollution on the environment and human health. Understanding these requirements is essential for anyone installing or maintaining outdoor lighting fixtures in California.

The main objective of Title 24 Outdoor Lighting Requirements is to reduce the amount of light emitted from outdoor fixtures by limiting the wattage and lumens of the bulbs used. Additionally, the requirements specify the color temperature of the bulbs, the shielding of the fixtures, and the placement of the fixtures to minimize light trespass onto neighboring properties and the night sky.

One of the key elements of Title 24 Outdoor Lighting Requirements is the establishment of maximum allowable light levels for different types of outdoor areas. These light levels are measured in foot-candles (fc) and vary depending on the intended use of the area. For example, parking lots and roadways have higher allowable light levels than residential areas and parks.

To meet the light level requirements, fixtures must be properly shielded and directed to ensure that the light is emitted only where it is needed. Shielding can be achieved through the use of hoods, louvers, or other devices that prevent light from escaping upward or sideways. The fixtures must also be placed at the appropriate height and spacing to minimize light trespass.

In addition to limiting light output and shielding fixtures, Title 24 Outdoor Lighting Requirements also specify the color temperature of the bulbs used. The color temperature of a bulb is measured in Kelvins (K) and indicates the color of the light emitted. Bulbs with a lower color temperature (warm white) emit a more yellowish light, while bulbs with a higher color temperature (cool white) emit a more bluish light. Title 24 recommends using bulbs with a color temperature of 3000K or less to reduce light pollution and glare.

Compliance with Title 24 Outdoor Lighting Requirements is essential for all new and existing outdoor lighting fixtures in California. Non-compliance can result in fines and penalties. It is important to consult with a qualified lighting professional to ensure that your outdoor lighting system meets the requirements and minimizes light pollution.
