LEDs vs. Incandescent Lights

If you’re hesitant to make the switch to energy-efficient LEDs, you’re not alone. Thanks to advances in LED technology, you no longer have to sacrifice the familiar warm glow of a traditional incandescent bulb if you want to upgrade to efficient lighting. Today’s LEDs are capable of replicating the look and feel of an incandescent bulb without wasting excess energy. Not only do they take less energy to power, LEDs also last significantly longer, are more durable, and are just as cheap as a traditional bulb.
