Even though LED (light-emitting diode) light bulbs are longer lasting, more energy efficient, and provide warmer light than fluorescent bulbs, they are probably too expensive to use in your home. But in large-scale projects, the energy savings and low maintenance costs of LEDs might be worth the high price.The Migros Supermarket in Essenbach, Switzerland, expects its new LEDs to last an average of 16 years (based on 10 hours a day of use, six days a week), while providing superior illumination. An added bonus: it has virtually eliminated the time-consuming process of changing bulbs. The municipal parking garage in Raleigh, North Carolina, switched from stale orange fluorescents to LEDs this spring. The benefits have gone beyond the 40 percent reduction in the garage’s energy bill: The number of drivers who felt “very safe” in the parking lot increased 76 percent.

Why mass shootings spawn conspiracy theories
Mass shootings and conspiracy theories have a long history.
While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.
When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.
Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.
