Denver’s night glow will turn from orange to white with 44,000 new LEDs

The conversion of about 44,000 outdoor fixtures to light-emitting diodes will leave the city of Denver washed in a neutral, whiter light. As the current sodium lights are removed, it might look as if someone’s removed an orange filter from Denver’s evenings. “It seems white, rather than a yellow glow. They called it a white-warm light,” said Nancy Kuhn, spokesperson for Denver Public Works. That change has raised health concerns in the past, but Denver officials say they’re using new technology that minimizes the effects of blue light.
