It’s well-known that LED (light-emitting diode) lightbulbs are the most energy-efficient bulb types, but caution should be used when considering them for outdoor lighting. The reason? Scientists have discovered that the unnatural lighting is attractive to migrating birds, and it can lead to injuries and death when birds collide with buildings and other structures that reflect that light. The solution is not to abandon LED bulbs, but to choose ones that have filters that block the direct light. Look for LED bulbs that are designed specifically for outdoor use or have color coatings on the bulb to diffuse the artificial light.
