Hawaii Class I Lighting is defined as lighting where CRI is important in places such as eating areas, repair shops, and recreational facilities. Lights in this category may be LED or low-pressure sodium but they must be fully shielded. All lights in this category must be off from 11 pm to sunrise.
Hawaii Class II Lighting includes lighting that is used for general illumination of grounds, such as walkway lighting, roadway lighting, and sidewalk lighting. This lighting must also be fully shielded and low-pressure sodium, with no exceptions.
Hawaii Class III Lighting, which is considered to be the least essential type of lighting, includes any decorative lighting such as sconces for buildings, landscape lighting, or pond lighting. All decorative lighting must be fully shielded.
Low-Pressure Sodium vs PC Amber LED
Hawaii’s lighting ordinances prioritize the use of low-pressure sodium (LPS) lighting for outdoor applications, such as street and tunnel lighting. LPS, an induction lighting type related to fluorescent and neon lights, is favored for its extremely narrow wavelength. This feature is crucial for dark-sky compliance as it minimizes light pollution that could interfere with astronomical observations, providing a clearer view of the night sky without the dispersion typical of broad-UV spectrum lights.
Contrasting with LPS, PC Amber LEDs offer advanced technology benefits. This specialized form of LED lighting not only matches the low light pollution benefits of LPS but also surpasses it by providing better color rendering and higher lumen output. This makes PC Amber LEDs suitable for applications requiring both environmental sensitivity and enhanced visibility. Therefore, while both lighting types serve the goal of reducing light pollution, PC Amber LEDs offer additional advantages in terms of visual quality and efficiency without compromising the dark-sky-friendly attributes essential in Hawaii.
The chart to the right shows the difference between LPS and PC Amber LED.
