LED Energy Savings — How Much Can You Really Save?

The average household spends a significant portion of its electricity bill on lighting. Switching to LED can cut that cost by 75-80%. Here are the real numbers.

The Math

A traditional 60W incandescent bulb costs about 12 EUR per year to run (assuming 4 hours/day). An equivalent 9W LED bulb costs about 1.80 EUR per year. Replace 20 bulbs and you save over 200 EUR annually.

Longevity Savings

Incandescent bulbs last about 1,000 hours. LED bulbs last 15,000-25,000 hours. That means you buy 15-25 fewer bulbs per fixture over the lifetime of the LED. At 2-3 EUR per bulb, the savings add up.

Heat Reduction

Incandescent bulbs convert 90% of energy into heat. LEDs convert 80% into light. In summer, this means less heat in your home and lower air conditioning costs.

Maintenance Savings

In commercial spaces, the cost of replacing bulbs includes labour. LEDs dramatically reduce maintenance costs because they rarely need replacing. This is why offices, shops, and warehouses switched to LED years ago.

The Bottom Line

For a typical home, switching entirely to LED saves 150-300 EUR per year on electricity alone. Add the reduced replacement costs and the payback period is usually under 12 months.
