Irvine's streetlights are being replaced with LEDs, and residents across the city report the newer fixtures as harsher and harder to look at. The city's code sets no ceiling on how bright a light may be and no limit at all on how blue. We are a group of concerned residents asking Irvine for a standard.
Intense glare and blue-white light strain the eyes and leave uneven pools of light and dark that make it harder, not easier, to see at night.
Blue-rich light at night suppresses melatonin and delays circadian timing, and unshielded fixtures put that light where people sleep. Residents with migraine, autism, or photophobia are affected more still.
Unshielded fixtures spill into the sky and into bedrooms and yards, causing unwelcome nuisance in homes and washing out the night sky.
Irvine's code requires that outdoor lighting be confined to the site and that neighbors be protected from glare — but it gives no way to measure any of that, and sets no limit on color temperature. Our goal is a city-wide standard with enforceable numbers, for lighting that is
Use only as much light as the task needs; this includes picking the lowest possible color temperature (amber tones wherever possible, and no more than 2700K outdoors at night).
Use timers, dimmers, and sensors so light runs only when and where it's actually needed.
Shield fixtures to aim light down at the ground — not into eyes, windows, and the sky.
Our three R's distill the Five Principles for Responsible Outdoor Lighting, published jointly by DarkSky International and the Illuminating Engineering Society. Irvine can build on them.
The American Medical Association recommends that community street lighting be shielded and no higher than 3000K to cut glare and protect sleep. (AMA, 2016)
California's building codes already treat warmth and shielding as good practice: CALGreen's voluntary tier measures cap general hardscape lighting at 3000K, and the state energy code limits backlight, uplight, and glare from large outdoor fixtures. Both carve out public street lighting — which is exactly the gap a city standard exists to fill.
Lighting does make roads safer, and we're not asking Irvine to turn anything off — the question is where the light goes. Glare from an unshielded fixture scatters inside the eye and washes out contrast rather than adding to what you can see. Bright pools next to dark gaps are harder to see into than steady, even light. Good lighting is quality lighting.
Not meaningfully. Warm and shielded aren't upgrades you pay extra for — color temperature is an ordering option, and modern LED streetlights are full-cutoff by design. Warm LEDs are slightly less efficient, but the difference is small next to the savings LEDs already deliver over the lights they replace.
Residents across Orange County have signed our petition — and the list keeps growing.
After one resident spoke up, the city modified the lighting in one neighborhood.
We have presented the problem to Irvine city staff and council members and are in ongoing dialogue with them.
A short, polite note from a resident carries real weight. Copy our template, add your name, and send it to the Irvine City Council.
Dear Irvine City Council,
I'm an Irvine resident concerned about the glare and brightness of the city's new LED streetlights. I'm asking the Council to adopt an outdoor lighting standard requiring warm (2700K or lower), well-shielded, appropriately dimmed lighting — the shielding and warmth the American Medical Association recommends.
This isn't a request for less light. It's a request that the light we already pay for lands on the pavement instead of in bedrooms and eyes.
Thank you for your time and consideration.

The Irvine City Council meets on the second and fourth Tuesday of each month, with time set aside for public comment. A minute at the podium from a real resident can move the needle more than anything.
Share this page and our videos with neighbors, and follow along. The more Irvine residents who know, the stronger the ask.
Sign the petition and help bring warm, shielded, night-friendly lighting to Irvine.
