Comparison of Different Types of Bulbs

CFL, halogen, led, or filament, here is a comparison of different light bulbs available on the market. Make your choice!

• CFL

Life: of 6000 to 7000 hours (15000 hours for some bulbs)
Performance (or flux) light: 50 to 70 lumens per watt.
Ignition time: 10 seconds to reach 60% of the luminous flux. But “instantaneous luminous flux” templates exist.
Light type: The range is broad. She’ll warm white light (2700 to 3000 kelvins) to bluish light “light of day” (6000 kelvins).
(Indicative) price: €8 for a spiral bulb of 12 watts (equivalent to a lamp filament of 60 seconds).
(CFL) CFLs or low consumption (LBC) belong to the same family as the fluorescent tubes, the good old neon lights. They are more effective and less-intensive electricity (from 75 to 80% savings) than the old bulbs. Thus, a 15-Watt CFL produces light output equivalent to that of a lamp filament of 65 watts!

Today, many models, especially suitable for lighting, are available. Progress has been made to warm their lighting. But the light of fluorescent remains cold and is better suited to a bathroom and a living room…

Finally, if their starting time has been reduced. better to avoid to install them in the hallway, stairs or cellars.

Two flats: CFLs contain mercury (0.005%). Drop them in a dump or bring back them to the Distributor. They also generate an electromagnetic field, so it is advisable to keep at a distance of 30 cm to the minimum of the lamp.

• The High Efficiency Halogen

Service life: 3000 hours
Performance (or flux) light: 15-27 lumens per watt
Ignition time: snapshot
Light type: warm white light (from 2500 to 3500 watts)
(Target) price: less than €2 for a 46 watt bulb.
Where to find? Ruedesampoules.com.

Halogen lamps consume 30% less electricity than traditional incandescent bulbs, but remain much less sober than the CFLs. They light up immediately and can be installed on dimmer lighting devices, nice for “balancing” the light.

Attention: The halogens of class C will be withdrawn from the market on September 1, 2016. Won’t stay on sale than models with nerve G9 (minibulbes for luminaires) and R7s (bulbs “pencils” to streetlights).

• Light-emitting Diode

Life: of 20000 to 40000 hours.
Performance (or flux) light: from 40 to 80 lumens per watt
Ignition time: snapshot
Light type: white light blue for the most common models (6000 kelvins)
(Target) price: 6 to €35

According to dealledlights.com, light-emitting diode (led or LED) are the most enduring and efficient. Benefits: no delay in ignition and resistance to the cold and impact. Their performance is comparable to the LBC and they contain no mercury. Their light is cold, but recent patterns generate a warm white light.

Attention, the national agency of health security (Anses) alerted about risks to the retina of the large proportion of blue light in some LED lights. Avoid them in the rooms of children or persons sensitive to light. Furthermore, LEDs contain recyclable, electronic components do not throw them in the trash.

• Filament Bulbs

Life: about 1000 hours
Performance (or flux) light: from 9 to 15 lumens per watt
Ignition time: snapshot
Light type: warm white light (from 2500 to 3500 kelvins)
(Target) price: withdrawn from the European market, but still on sale on the Internet. Variable prices.
Where to find? Falbala – luminaires.com

Since December, 2012, manufacturers have more right to put on the market lamps traditional incandescent or halogen ranked from D to G. Those nostalgic for filament bulbs will have trouble finding. But still sell specialized internet sites: from €1.75 for a standard 40-watt bulb, nearly €6 for a bulb of 25 watts flame-shaped, for example.

Other sites distribute “decorative” bulbs, not covered by European regulations. Imported from Asia, these lamps, often retro and original design, are much more expensive – from € 18 to € 23 according to the model – and provide a very warm, orange light.
