Halogen describes the gas inside a lamp re-depositing the spent
tungsten back on the
filament which allows for more output, smaller
filament in many cases, and a higher
color temperature, and longer lamp life than an
incandescent lamp (also in many cases unless high output version).
Quartz describes the higher temperature type of glass used on a
halogen lamp instead of Soft Lime glass used on
incandescent lamps. It's purity and higher operating temperature on a
line voltage lamp (84v or higher) will be effected by touching it - oils from the skin, or dirt, or
fog goo
etc. coating and bonding with the pure glass in having adverse effects to it working properly = including explosion stated above and you learned. A low
voltage halogen lamp c. 64v or less does not get hot enough for touching the
globe to fail, nor will it explode. Been professionally doing lamps since about 1993 and touching a low
voltage lamp has never been the cause of explosion I have seen. Not a bad idea to retain the no touch concept though.
There is a few types of
halogen lamps which do not use a quartz
bulb/
envelope. A few discontinued A-Lamp types and some PS-52
ANSI DKZ types amongst a few others. They had quartz capsules inside of a larger standard soft lime glass outer
globe. Otherwise it hurts my brain when people confuse
halogen verses quartz as two different lamps, just as much as when people
call a lamp a
bulb.
Smallest
filament design (below lamps cited) eludes me in ever understanding C-Bar6 verses c-6,
Axial verses TransAxial, C-6 oval, 4.6x3mm area... What I could tell would be the smaller the number or size, the more
point source
the light source. Osram had/has an excellent free PDF
book on the design factors going into a
halogen lamp's design. Pick one of the
ANSI lamps below such as the EVA, scroll down to the "doccuments" section and hopefully this
book is still an option to download. It will explain all about
halogen lamps including
filament size and structure. Dependant on the brand, Philips for instance from euro catalogues state area the
filament takes up instead of it's size and support structure. That's a better concept but does not persay translate to other info.
Below are some of many lamp notes I have taken over the years as I had to learn lamps that might be of help.
Far below is a list of lamps similar to the one you plan on using. Last number noted assuming my table will not transfer is expected lamp life. Note, given
LED lamps are really popular now, many or most lamps listed are probably discontinued, but you will see some with even higher output or smaller
filament sizes that might still be available to search for.
ANSI = American National Standards Institute. A consensus organization which coordinates voluntary standards for the physical, electrical and performance characteristics of lamps, ballasts, luminaries and other lighting and electrical equipment. The
ANSI code is one of a few basic standards for describing lamps. J-Code or Japan code as per the lamp you describe above is a fairly standardized amongst brands description of the lamp which could also be
ANSI coded. GE also in description code has a recognized lamp description code standard similar in many ways to the J-Code.
Capsule = The most compact
halogen lamps and can be used for a wide range of applications. The capsules are low pressure lamps produced according to
IEC 357 with a special operating filling gas pressure ≤2.5 bar to be used in luminaries without front glass (according to
IEC 598). The capsules have an
axial filament, a
clear bulb and have a G4 or GY 6.35
base.
Axial filament gives higher light output in combination with luminaries and a uniform beam.
Corex Glass = c.1964 In some larger sizes (wattages) for special purposes, a special glass called Cores is being used. This permits a smaller
bulb than would be possible with ordinary glass because of the heat involved in operation. (?Later called Quartz Glass?) (A Syllabus for
Stage Lighting, Stanley
McCandless c.1964 p.10)
Fused Silica = Improved Quartz Glass with silica fused to the wall material. Used on high fill pressure/wattage lamps for over 50% more efficiency.
Hal =
Halogen Lamp - A short name for the
tungsten-halogen lamp.
Halogen lamps are high pressure
incandescent lamps containing
halogen gasses such as iodine or bromine which allow the filaments to be operated at higher temperatures and higher efficacies. A high-temperature chemical reaction involving
tungsten and the
halogen gas recycles evaporated particles of
tungsten back onto the
filament surface. Also called a Quartz lamp, though this is a term for the higher melting temperature glass enclosure used on
halogen lamp
HRG =
Bulb made of Special Thremal-Shock Resistant & Heat Resistant Glass
Qxx = 1st Digit, Lamp Code for
Halogen Lamp w. Quartz Glass.
Quartz = Common description of the type of glass used in and implying a
Tungsten Halogen Lamp.
Quartz = A type of glass used for
halogen,
HMI, and other high output / high temperature type lamps. This type of glass construction is used extensively on
Stage and Studio lamps. Quartz glass is more expensive but has better reliability and virtually constant color temperatures. They also are capable of withstanding higher temperatures without deforming or breaking which allows for a smaller lamps
envelope in
thickness and diameter in closeness to the heat source. Quartz glass is also able to support coatings such as
Infrared and
Dichroic coatings used to prevent the more harmful un-seen rays of light from leaving the lamp and keeps both the
fixture’s lenses and beam cooler. This also allows for a hotter
filament temperature without extra energy used to achieve it. When
Halogen gas is combined with Quartz glass, a hotter
filament is also able to become smaller and more
point source. For
incandescent lamps, soft lime glass is used because the soft glass is easy to work with and will telerate temperatures up to 350°C.
Tungsten Halogen Lamps =
Halogen Lamps are
tungsten fliament
incandescent lamps filled with an inert gas (usually krypton or xenon to insulate the
filament and decrease heat losses) to which a
trace of
halogen vapor (bromine) has been added.
Tungsten vaporized from the
filament wire is intercepted by the
halogen gas before it reaches the wall of the
bulb, and is returned to the
filament. Therefore, the glass
bulb stays clean and the light output remains constant over the entire life of the lamp. (p33, Sylvania Lamp &
Ballast Product Catalog 2002)
Low
Voltage Dimming: Low
Voltage halogen lamps should not be dimmed by more than 10% of their rated
voltage since this will result in a reduction in life. Standard
tungsten filament lamps (with no
halogen filling), can be dimmed to zero volts, resulting in virtually endless life. However if low
voltage tungsten halogen lamps are dimmed by more than 10%, the lamp will be operating at too low a temperature and the free halogens in the gas fill, will attack the cooler parts of the
tungsten filament i.e. where enters the quartz or glass
envelope. The
wire at that
point will then be eroded and eventually will fail. So if dimmed by 10% or more low
voltage tungsten halogen lamps will not have an extended life but are unlikely even to reach their rated life. - Philips Website, Optical p1
