 – What is a lumen?

 – Why use these energy-saving bulbs?

– Comparison: energy saving bulb and conventional bulb

 

An energy-saving bulb uses about 5 to 8 times less electricity than a regular bulb.

As for ecological energy-saving heating, you can realize actual electric energy savings by consuming smartly.

Introduction

The energy-saving bulbs, also called low-energy lamps (LBC), need 15 times less energy than a traditional bulb (incandescent lamp) for the same quality of light.

These energy-saving bulbs do not have a filament, unlike traditional lamps.

 – On the other hand, they contain fluorescent powders and gas based on mercury vapor.

 – This means that the electrical discharge in the mercury vapor causes the emission of ultraviolet radiation.

This radiation, invisible to humans, causes the fluorescent powder that lines the tube inside to emit white light.

The base of the bulb is equipped with an electronic ballast.

Fluorescent tubes are also part of the category of energy-saving lamps because they also save electricity.

As for the LED (light-emitting diode), it consumes only a few watts.

 – It can be used as ambient light and for lighting a room.

 – It has a very long life, but this lighting technique requires costly materials.

A small aside, in your garden, solar lighting aims to absorb natural radiation during the day and restore it for free in the evening.

What is a lumen?

The luminous efficacy of an energy-saving bulb is calculated in lumens per watt (lm/w).

A high luminous efficacy indicates that the lamp will provide much light (expressed in lumen) for minimum power consumption (in watts).

Why use these energy-saving bulbs?

An energy-saving bulb lasts 8 to 10 times longer than a regular bulb.

However, the initial investment is more expensive and pays itself in about two years of use.

Using low-energy light bulbs allows you to save on the “specific” electricity bill, i.e., lighting, cooling, household appliances, and multimedia. The lighting item alone represents 15% of the consumption.

Good to know: avoid buying low-end bulbs that don’t offer the required efficiency. In addition, these energy-saving bulbs are not very durable.
