Why LEDs Save Money

LEDs consume 80–90% less electricity than incandescent bulbs while lasting 15–25 times longer. That translates directly into lower electric bills and fewer replacement costs.

Example: Living Room with Six 60W Bulbs

If each bulb runs 5 hours per day:

TypeAnnual CostBulb Life10-Year Total
Incandescent (60W)$761,000 hrs$890
LED Equivalent (9W)$1215,000 hrs$120
You Save$64/year$770

Plus you only replace LEDs once every 8 years instead of annually.

Frequently Asked Questions

Do LEDs really last 15–25 years?

At 5 hours/day average use, yes. Heavy use shortens lifespan. LEDs also don't suddenly burn out – they gradually dim over time.

Are LEDs worth it if I'm moving?

Absolutely. Moving 20 LED bulbs adds only 2 lbs to your box. The instant payback makes them portable upgrades to any home.

What about color temperature?

Warm white (2700K–3000K) mimics incandescent. Daylight (5000K–6500K) is better for task lighting.

Do LEDs work with dimmers?

Yes, but check for "dimmable" on the packaging. Non-dimmable LEDs may flicker or hum on dimmed circuits.
