a purple background, with three white stars stacked vertically and numbered 1-3. Text reads "Dark sky friendly lighting has...1) brightness <1,000 lumens 2) warm color tempearture: 2,700 K or less 3) fully shielded and directed downwards...our migratory birds appreciate your Dark Sky friendly lights!" bottom shows two fully shielded lights (where the lightbulb is completely covered by the housing) and a red and orange hummingbird
a purple background with white text that reads "What does warm light mean? How "warm" or "cool" a light source appears is described by Correlated Color Tempearture (CCT), aka color temperature, measured in kelvins (K). Lower CCTs are "warmer" in appearance, while higher CCTs are "cooler" in appearance., 3 squares with progressively more saturated yellows and black text reading: 3000 K warm white, like tungsten-halogen lamps, 2700 K warm white, like 100W incandescent lamps (this one has a white circle around it, pointing to text underneatht hat says "best for migratory birds"), 2600 K warm white, like 60W incandescent lamps. bottom has 4 migratory birds-marbeld godwit, wilson's warbler, varied thrush, and snowy plover
background: a starry sky seen between two rocky cliffs, between which lies the ocean. text reads: Migratory Birds Travel at Night... ...to use stars for navigation, avoid predators, fly in calmer air, avoid overheating, and to have opportunities to refuel during the day. For example: Snowy Plovers, Marbled Godwits, hummingbirds, vireos, and buntings. At the bottom is 4 pictures of birds: snowy plover, marbeld godwit, varied thrush, wilson's warbler. top right has a red and orange hummingbird.
background: a starry sky seen between two rocky cliffs, between which lies the ocean. text reads: Light pollution disrupts our circadian rhythm...Studies have shown the level and duration of darkness we experience before sleep is more important than the amount of time spent in bed. Melatonin, the hormone that helps you sleep, can be suppressed by exposure to blue light. Artificial light at night has been found to contribute to certain cancers, heart disease, diabetes, obesity, mood disorders, and insomnia. (International Dark Sky Discovery Center, 2025)
Humboldt County's new Outdoor Lighting Ordinance has many people asking, “How can I protect the night sky?”
