The LED Diet

A lot changes in 20 years. Newborns become college students, the House of Representatives updates its roster 10 times, and a boulder becomes a slightly smaller boulder. But, for disciples of The LED Diet, one thing stays the same: their light bulbs. LED bulbs can last for up to two decades, casting homes in the low-energy, cooler-burning light. Three years of testing have resulted in an inventory of superior bulbs designed for spaces ranging from kitchens and ceiling fans to sparkling chandeliers. In addition to saving energy, "LEDs are certainly more attractive than the curly CFLs," one of The LED Diet's clients told the Washington Post.

LED comprehensive lighting plans can cut down on energy usage from lighting by up to 80%. They also come equipped to install the bulbs themselves, meanwhile ensuring that they leave the abode spotless or with precisely its original number of spots by covering their shoes. Along with bulbs, they can also install thermostats and LED-compatible dimmers. Afterward, they'll happily replace a bulb if it burns out or, if necessary, remove and refund everything within 90 days of installation.
