For most people, this lamp is something that most of them refer to as a push
and turn base. The bayonet base isn't like a screw-in base at all, it has
smooth size and a couple of nubs at the bottom which hold it in place.
What's nice about this type of lamp is the way it rest securely in the socket
with no chance of it falling out. There are many kinds of halogen bulbs
that look similar, but many times they can be very different, so it's important
that you know what you have. Among halogen lamps, this type may be perhaps the
widest category and encompasses
everything from low wattage bipin lamps to higher wattage double contact bayonet
halogen bulbs, so it can be a little overwhelming.
But when you look at these bulbs, there are different bases, bulb sizes, finishes,
voltage and of course the wattage. Like all halogen bulbs, they are filled with a special gas that actually rebuilds the filament and
provides longer average lifespan than normal incandescent bulbs. These halogen
lamps burns about 10 percent brighter,
whiter, and hotter than normal incandescent bulbs. Extra heat is typically not a
benefit, but whiter, bright light is something that is useful in a large number
of lighting applications. The applications and light fixtures that these
have been used in are almost endless. The most common lighting task for
these are high areas such as auditoriums or churches, in that
case they're usually in a recessed light fixture.
When trying to identify your double contact bayonet halogen, one of the best places to
start is at the base of the lamp, the part where it makes it's electrical
connection. Here's how to tell the difference between various types of
bases and so on. The smaller bipin lamps will have two pins which have a
specific spacing in millimeters which could be anything from 4 to 9 millimeters.
These are usually a lower watt lamp, but some get into a high watt category.
They vary from 12 to 120 volts. Another type of single ended halogen has
one of several bases which would be a minican (MC or E11), DC (double contact
or Candelabra (E12). These are the lamps which typically have a higher
wattage but some are lower as well. These voltage is almost always 120
volt or 130 volt for longer life. If you have flood light fixtures,
sometimes these are used because of the the small space and large amount of
light they produce. The places where all these have been used over
the past 30 years are typically those applications where a greater beam control
is desired and lots of light. Double contact bayonet halogen light bulbs are available in wide variety
of bulbs and wattages as low as 50 watt all the way up to 1000 watts. Of
course, the lengths in different wattages would also vary slightly. We
have two different brands for these which would be Sylvania or Westinghouse.
Both offer high quality manufacturing and have a long life which we see in the
day-to-day feedback we get from our customers. In our shopping cart, we
have them listed with a DC designation such as the following, 75Q/DC, 100Q/DC,
150Q/DC, 250Q/DC and 500Q/DC. These also come in a clear or frosted glass
and the preference is yours.
Like all halogen bulbs, these should not be touched with your skin in any way
and sometimes the packaging comes with a foam or paper wrapper to prevent this. If they
are touched, the life span of the bulb will be greatly reduced. In case you ever
do touch a bulb, wipe it thoroughly with a soft cloth. Bulbs that
are covered, like the PAR and some of the MR halogen bulbs, are okay to
touch, since you are not touching the actual bulb but a heavy, thick glass that
covers the light bulb. Most commonly, they are put into an enclosure but
be aware of touching a halogen capsule itself directly, is not a good idea as it
will shorten lamp life.
From flood lighting, task lighting or in a large commercial space, you will most likely find
double contact bayonet halogen lamps used in many kinds of lighting applications. The
compact size of these halogen lamps make it
possible to put them in almost any small space and produce high illumination.
