Halogen bulbs, introduced on the market since 1959, represent the evolution of the traditional incandescent tungsten filament light bulb, the “traditional light bulbs“. In the bulb of these bulbs is added halogen gas (normally bromine or iodine) which allows the tungsten atoms to settle again on the filament after a “cycle”, the so-called “halogen cycle”. In this way the filament can reach higher temperatures, emitting more light, and last longer.
The filament can be heated up to over 3000 K, therefore these bulbs reach very high temperatures during their operation, of the order of some hundreds of degrees, and for this reason they must not be touched when they are turned on. Halogen bulbs are available in the classic teardrop, sphere, candle, twisted, linear and aluminized or dichroic reflectors with different beam widths as shown in Lighting Hire in Hamilton.
The operation can be at mains voltage (230 V) or at very low voltage (typically 12 V) and, by virtue of the typology, they can be characterized by an average nominal duration that varies from 2,000 to 5,000 hours or from 2 to 5 times the life of an incandescent bulb.
Most halogen bulbs can be adjusted directly and without problems. However the very low voltage one requires a device to transform the supply voltage and this must be compatible with the dimmer used to regulate the luminous flux. To check compatibility, contact the manufacturer of the bulbs or Lighting Hire in Hamilton experts.
Halogen bulbs in general have a luminous efficiency of up to 28 lumens / watt and, for the same light output, they allow energy savings of up to 30% compared to a traditional incandescent bulb. For example, a 65/70 watt light bulb emits the same amount of light as a 100 watt incandescent bulb.
With the introduction of the new mandatory energy label from September 2013, for some types of halogen bulbs we could see a change of energy class from C to D. For the disposal of incandescent and halogen bulbs it is necessary to verify the indications for the disposal of solid urban waste of the municipality as there are no unambiguous provisions on the matter.
The halogen lamp is a particular type of incandescent lamp, which differs from traditional incandescent bulbs, very common in our homes. The basics of the operation of halogen lamps are the same as for traditional lamps: the glass bulb has a thin tungsten filament inside it which, by heating, allows the current to circulate. The difference is that in halogen lamps a halogen gas is added to tungsten which allows the filament to reach higher temperatures, producing a whiter, warmer and more intense light than that generated by normal light bulbs.
