Here’s why you might stop.
When it comes to serious energy savings, however, LEDs completely changed the game.
The efficiency of LED lighting compared to traditional incandescent lighting is staggering.
Back in the day, it made sense to turn the lights off when you left the room.
LED lights use a small fraction of the energy traditional incandescent bulbs do, though.
And let’s say you leave them on for 5 hours every night.
These bulbs are perfect for cozy evening ambiance and offer dimmable warm lighting in the 2200K-2700K color temperature range.

Suppose you have ten traditional 60w incandescent bulbs.
They consume a total of 600w per hour or 0.6 kWh.
Each evening when you leave those ten bulbs on after work, it costs you $0.36.
Per month, it’s $10.96, and per year it’s $131.49.
These bulbs are perfect for cozy evening ambiance and offer dimmable warm lighting in the 2200K-2700K color temperature range.
Most 60w-equivalent bulbs use between 8-9w of energy, so we’ll use 8.5w for our calculations.
So now your per-hour energy use isn’t 600w, it’s 85w.
Efficient LEDs or not, there’s no reason to leave attic or closet lights on 24/7.
At that price point, you’re talking 1,000 hours of operation to hit one dollar.
