Blue-light emitting LED bulbs have taken off with consumers because they have few downsides -- they're bright, use far less energy and last much longer than other types. In fact, the inventors just won a Nobel Prize, proving their huge benefit to consumers and society. But it now appears there's a teeny issue: flying insects. Scientists in New Zealand tested blue-light LEDs (which look white due to a phosphor coating) against regular yellow-hued sodium-vapor streetlights. The result? The LEDs attracted nearly 50 percent more insects, regardless of the brand and type used. While that could be a pain for your next porch party, there's a more serious downside. The researchers said that when used on city street lamps, the bulbs could interfere with the food chain and even draw invasive species like gypsy moths.
