On the fence about installing a tubular daylighting device? Consider that the Solatube Smart LED System can actually help you save on monthly lighting expenses. Here’s how it works: During the day, the Smart LED delivers natural sunlight to a part of the home interior, such as the hallway, at no cost, because sunlight (obviously) is free. It's when sunlight levels recede that the Smart LED really sets itself apart. Equipped with built-in, highly efficient LEDs, the Smart LED System can provide nighttime lighting up to 94 percent more efficiently than a traditional fixture can. If you want to make your Smart LED System even more of a money-saver, go for the optional occupancy sensor. Depending on whether or not the sensor detects someone in the room, it activates or deactivates the LED bulbs accordingly. That way, you can ensure that if a family member always forgets to turn off the hallway light, you don’t end up paying for the mistake at the end of the month. The occupancy sensor option doesn’t only mean savings, though. It also means the convenience of never again having to think about hitting the light switch!
