LED: Why 3000K or Less

3000 Kelvin Shielded LED Lights Have Quickly Become the Standard for Outdoor Lighting

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.

The Accelerated Transition to LED Environmentally Responsible Lighting has Brought a New Standard to Outdoor Fixtures

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.

A central deficiency of the early generation LEDs was the excessive amount of blue light they emitted, leading to complaints that they were too “cold,” glaring, and created an uncomfortable environment. Nonetheless, the only option available at the time that provided adequate lumens per watt and that were still energy efficient were 5000K+ LEDs.

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. The lower kelvin lights are cost and energy efficient, safer, better for human health and wildlife conservation, and contribute less to skyglow.

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 and around the world. IDA anticipates that as LED technology advances it is only a matter of time before 2700K or lower becomes the new norm.

The following municipalities and organizations understand the importance of responsible lighting and have taken action to provide their constituents safe, cost effective, environmentally friendly street lighting:
