Consider that the Children's House alone uses more than 75 bulbs in its four classrooms, office, restrooms and meeting space. Next, consider that changing just one incandescent light bulb to a CFL Energy Star bulb will save about $30 over its lifetime and pay for itself in about 6 months. It also uses 75 percent less energy and lasts about 10 times longer than an incandescent bulb. The savings to Sunstone in switching these light bulbs over to CFLs is more than $2,250 in energy savings-who knew a $10 investment in light bulbs could feel this good?!
