LEDs are saving insects and butterflies

The Austrian Environmental Law Commissioner Wolfgang Wiener observed the slow but sustained adjustment to LED streetlights from a very specific point of view. He announced in an interview, that LED lights are not only saving money and reducing the electricity consumption, but are also saving insects, which are night-active. Those insects are geared to the UV light of luminaries. Mercury lamps, as opposed to LEDs, radiate UV light and disturb the orientation of insects as butterflies. That’s the reason, why a big number of insects is flying into the streetlights and dies due to the heat of those lamps. The usage of LEDs as streetlights could save billions of insects per year and ameliorate their ecosystem.
