Which type of light bulb is the most economical to use?

Light bulbs are one of the devices that contribute significantly to a family's monthly electricity bill.

Specifically, according to Vietnam Electricity Group EVN, lights will consume 10-15% of a family's electricity costs. However, if you know how to use it correctly and choose the right type of light bulb, you can save up to 70% of electricity.

Currently on the market there are many different types of light bulbs and electric lights such as LED bulbs, Halogen bulbs, CFL compact bulbs, fluorescent bulbs and incandescent bulbs. Among them, LED light bulbs are the type that use the least amount of energy when operating, helping to save the best electricity.

Specialized sites have measured over 5 lighting levels of different types of light bulbs to provide specific comparison tables, helping users more easily visualize the electricity consumption between different types of lights.

It can be seen that incandescent bulbs consume 25W of electricity at the lowest lighting level of 220+, and 100W at the highest lighting level of 1300+, so they consume the most electricity.

The light bulb that consumes the least amount of power and is the most economical is the LED light bulb that consumes only 3W when at a lighting level of 220+, and 70W when at a lighting level of 1300+.
