Lighting devices containing LED bulbs are energy-saving light sources. The LED "bulb" doesn't glow, so there is no heating that causes a loss of approx. 90% with traditional light sources. One of two headlights with the same brightness has a 35 W halogen bulb with a lifespan of 2000 hours, the other 3 with 1 W each works with an LED bulb with a lifespan of 30,000 hours. The price of the halogen bulb is HUF 1,000, and the total of 3 LED bulbs is HUF 3,750. Let's calculate the costs of the two types of light sources during the almost three and a half year lifespan of the LED lamp! When evaluating the result note that the lamp is not
we use it continuously for three and a half years. It may only operate for two hours a day on average.
