It’s all about conserving energy while having the most reliable luminosity possible. LEDs are already an energy conserving measure. They allow illumination without as much energy output as regular lights have. The thing is, theyare slightly more expensive than regular lighting solutions, so many people have shied away from them. What they don’t realize is that the savings aren’t on the front end, but on the back end. LEDs last longer and use diminished amounts of resources.
