The rapid advancement of LED technology is unparalleled in the lighting industry, which has caused cities and utilities to reevaluate the specifications used for their street and area lighting applications. Early generation LEDs were typically 5000K or higher, which at the time was the upper end of the technology’s capacity for products that remained both economically viable and energy efficient.
Within just a few short years, the industry has dramatically improved the efficiency of LEDs, ushering in a new generation of 3000K “warmer color” products that emit less blue light. 3000K LED lighting saves energy and lowers costs, protects health and human safety, conserves nocturnal wildlife, and protects nightscapes.
Today, 3000K LEDs are the standard choice for outdoor lighting and are in use by dozens of municipalities – representing millions of consumers – both in the United States, Canada and around the world. Its anticipated that as LED technology advances it is only a matter of time before 2700K or lower becomes the new norm.
Save Energy & Lower Costs
3000K LED lighting is both economically viable and energy efficient.
Protect Health & Human Safety
High Kelvin lighting (greater than 3000K) create a harsh glare, making it difficult to see clearly at night. It can also suppress melatonin production, leading to disrupted sleep and other health risks. 3000K and less LED lights are the safest LED currently available.
Conserve Nocturnal Wildlife
Excessive outdoor lighting disturbs nocturnal wildlife and their habitat, negatively affecting birds, insects, turtles, fish and other species.
Protect Natural Nightscapes
Shielded 3000K or less LED lighting helps to reduce skyglow and improve nightscapes.
