According to the U.S. Department of Energy, LEDs offer the potential for cutting general lighting energy use nearly in half by 2030, saving energy dollars and carbon emissions in the process.
Most LED bulbs last between 25,000 to 50,000 hrs compare this to 1,000 or 2,000 hours from most incandescent and halogen bulbs. LEDs also save you money by using 70% less energy.
LEDs don’t have glass bulbs and they don’t have delicate filaments that can break from vibration. This makes them the most durable light bulbs available. They also contain no mercury, a known toxic substance found in CFLs.
This is a fancy way of saying “keeps shining like it did when it was new.” Other lights may lose 30% to 40% of their brightness after 1/2 their rated life, LEDs are known to maintain close to 90% of their initial lumens at half their rated lives.
Other bulbs’ frequent on/off cycles can cut the bulb life in half. But this cycling doesn’t have much impact on the life of LEDs.
Most light bulbs emit a lot of heat and, as you know, you would never replace them without first giving them a period to cool down. But LEDs remain cool to the touch on the front of the bulb and emit very little heat.
