How To Choose Different Types of Light Bulbs

What could be more ordinary today than pressing the button of an electric switch to see the room illuminate? Since “fairy electricity” has gone through our homes, we can see the night as in broad daylight!And there is a long time, when a single bulb gave a little light in the living room. On the contrary today, the choice is so vast that it becomes difficult to choose the right light bulb for good lighting. In order to illuminate your lanterns here is a small guide of the bulb.

The Incandescent Bulb

Originally the incandescent bulb is one invented by Edison in the late nineteenth century and improved over time. It is inexpensive but has a limited lifespan (about 1,000 hours) and, above all, is a major energy consumer, and virtually no longer exists in the European Union, which has been phasing out since 2009.

Halogen Incandescent Bulb

Technically, it is the little sister of the previous one: a filament of tungsten carried at high temperature but this filament is installed in a quartz glass containing halogenated gases under high pressure. This increases its lifetime, its brightness and there is virtually no loss of intensity over time.

It is available in 230 V or 12 V (very low voltage halogen).

But the halogen bulb is energy-intensive. Its energy classification is most often in category C or D. From 2016 (unless a postponement in 2018 is authorized by the European Union) only bulbs in categories A or B should be marketed Manufacturers have reacted and today there are halogen eco bulbs on the market. For an identical rendering, it consumes 20 to 30% less, has a longer life and meets criteria B of the classification.

THE +

Beautiful light with excellent color rendering

An instantaneous ignition

Possibility of installing a drive or a motion or presence detector

It can be disposed of in household waste

A very affordable cost

THE –

A limited lifetime (approximately 2000 hours and 3000 hours for the eco version)

Repeated stairs / stops use them prematurely

It heats up, pay attention to the risk of burning or fire

Of all the bulbs, it remains that which consumes the most even in economic version

He Low Energy Compact Fluorescent Bulb

This bulb is a copy of the neon tube, also known as the E27 LED light bulb defined by Healthvv, which has been lighting our classrooms, administrations and so on since the 1960s. Imagine a small neon tube, which would have met a compactor! And there he is, all withdrawn into himself. This tube contains argon and low pressure mercury. When you press the switch, an electronic ballast produces an electrical discharge that will ionize the gases and thus create ultraviolet radiation. The tube is internally covered with fluorescent powder, the beryllium which will convert the ultraviolet to visible light.

THE +

A good price-performance ratio

A high service life (about 8000 hours)

Good performance

THE –

A cold light and a color rendering significantly less good than with a halogen

It does not support a dimmer or motion detector

Repeated stairs / stops use them prematurely

It requires a few seconds of heating before reaching its optimum efficiency.

It contains hazardous gases and must be recycled

It produces electromagnetic waves

The LED Bulb

The LED bulb (Light Emitting Diode) or Diode Electro Luminescent in French (LED) has been present for a long time in electronic equipment or digital displays. Since the years 2000, the evolution of the technology makes it possible to present LED bulbs giving a light allowing the domestic lighting. These light bulbs have an interesting decorative potential for our living spaces. Nevertheless, it should be used wisely.

THE +

An unbeatable lifetime (30,000 to 50,000 hours)

Excellent performance

Good color rendering

An instantaneous ignition

Compatible with a dimmer (unless otherwise stated)

Decorative effects with color LEDs

It is recyclable to 98%

THE –

A high price

Pay attention to blue light which may present a risk to the eyes and glare
