It's one of the highest wattages available in a compact space, for different applications like stage and
studio and projectors, the BVA projector lamps.
These are made with a special shape which has an integral reflector and a two
prong base, one which is thicker than the other. Because visual communication
is important and stage lighting has special needs, these lamps will probably be
used long into the future. There are a variety of stage equipment
and projectors which
use the BVA lamp. The main purpose for a bulb like
this is creates a lot of light in a small space allowing for greater lighting
control, hence the integral reflector.
The brightness, as most people call it, needs to be adequate for dramatic
presentations as well as stage productions.
All of the BVA lamps regardless of the brand, have the same shape, that
includes Sylvania, GE or Eiko.
They are not interchangeable with other types of
stage or studio lamps. Almost always, the
voltages of projection lamps are different and the base or pins as well. The
BVA
projector lamps are 900 watts and 120 volt. In regards to
the shape, the BVA is very unique. The base will almost certainly not fit
in any other kind of socket. This lamp is very specific for the
application it's used in, so don't go looking for a replacement of some other
type, simply replace it with another BVA. Another thing to remember,
because these have a high light output, that usually means they have a much
shorter life. The life is shorter, the rating is only 75 hours, so
it's good to turn off the lamp when it's not in use. Another helpful tip is
that these bulbs should not be touched with your skin. The skin oils can react
with the glass and there can be some reactions which will shorten the lamp life.
Remember when replacing these, that they are
identified by a 3 letter code on the bulb itself. You'll see it somewhere
on the back or the top if it's more like a bulb as opposed to a reflector type
lamp. Sometimes you'll see a code such as BVA as described here or another
type with the letters ENX, FXL,
DAY, FHS, DYS, EVW or something similar to that. The ANSI 3 letter code
identifies that bulb as to the shape, wattage, voltage and any other standard
information. Unlike other types of bulbs, these have some standards across
various manufacturers, the only thing that varies is quality. We prefer to
sell the Sylvania brand as they seem to offer the best performance and the
longest life.
In summary, BVA lamps are used specifically for stage and studio light
fixtures and overhead projectors they
are made to operate with. Of course, you will need
projectors that will have the correct voltage and socket
for these projector bulbs. Whatever type of projection lamp you have, you
can get what you need from eLightBulbs. We have a large inventory
of projector bulbs for nearly every type of lighting application in the field. If
you need help identifying a projector bulb, our customer service
people can help you determine what you have.
