The DesignLights Consortium is inviting input into the second draft of its technical requirements for outdoor LED luminaires.
The Luna Technical Requirements are designed to mitigate adverse environmental impacts of lighting at night while providing appropriate visibility for people. As well as save energy, LED lighting’s attributes limit light pollution, sky glow and light trespass.
According to the International dark Sky Association (IDA), a third of all outdoor lighting in the US is wasted, costing facility owners some $3.3bn annually and responsible for 21 million tons of carbon emissions annually.
The DLC is a non-profit organisation which aims to achieve energy optimisation by enabling controllability and focuses on quality, people and the environment.
It is accepting comments on the draft policy through 22 October 2021 and anticipates releasing final Luna technical requirements by 16 December 2021. Once Luna is fully implemented in 2022, lighting manufacturers will be able to list and qualify their products to the specification.
Project designers will then be able to easily search for LED outdoor lighting products in a subsection of Luna Qualified Products on the DLC’s Solid State Qualified Products List (QPL), which will include luminaires that are both energy-efficient and have characteristics enabling best environmental practices for night-time illumination.
“Although night-time outdoor lighting is often critical for safety and navigation, negative impacts linked to over brightening of the night sky abound”
With the Luna requirements in place, utilities can better serve their customers’ needs for energy efficiency and dark sky goals. Municipalities and other public entities will also be able to adopt Luna requirements for use in their outdoor lighting projects.
“Although night-time outdoor lighting is often critical for safety and navigation, negative impacts linked to over brightening of the night sky abound, from disrupting human sleep patterns and disorienting wildlife to hindering astronomical research and wasting electricity,” said DLC executive director and CEO, Tina Halfpenny.
