LED bulbs are good and more energy efficient (less heat and uses less electricity), but they cost a significant multiple of what incandescent bulbs cost. It will take many years to cover the investment in the new bulbs to make it worthwhile to switch over if we now had a choice.

Who was it that used the phrase about the “giant sucking sound?”
A couple years back, I bought probably forty dimmable LED bulbs from Costco for around $300 or so. My power bill went from around $100 per month to $65. They’re already (twice) paid for. We’ve had one bulb fail, and it was brand new. Swapped it for a good one.
