One of the most common lamps for many different brands of
machines, projectors and viewing equipment are the DJL projector lamps.
These are made with a special shape which has an integral reflector and an
unusual base. Although the needs of
computer presentation has increased more and more, there are still many
applications of overhead projectors in service daily. Because visual communication
is important, it makes it
a popular lamp for the coming years. There are a wide variety equipment
and projectors which
use the DJL lamp, and they have a similar task which is to illuminate. In fact, some companies who make these
projectors have exchanged bulb types for greater light output while trying to
get better bulb life. The main purpose for a bulb like
this is the light it puts on a screen, how well it fills out the screen space.
The brightness, as most people call it, needs to be enough to gain good contrasts
of objects, writing or overhead transparencies.
All of the DJL projector lamps regardless of the brand, have the same shape, and sometimes the
exact same shape of another lamp which might have a different voltage or wattage.
That's one of the reasons they're not interchangeable. Almost always, the
voltages of projection lamps are different and the lumen output as well. The
projector lamps are 150 watts and 120 volt. In regards to
the shape, the DJL 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 DJL. 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 15 hours, so
it's good to turn off the lamp when it's not in use. Every instance of
time you don't have it on means the lamp will last longer. Another caution 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.
Another thing to keep in mind when replacing these is 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 DJL as described here or another
type with the letters ENX, FXL,
DAY, DYS, EVD, ELH 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 have two of the best manufacturers of all
types which are Sylvania and Eiko.
In summary, DJL lamps are used specifically for the machine, overhead or
slide projectors they
are made to operate with. Of course, you will need
projectors that will have the correct voltage and socket
for the 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
representatives can help you determine what you have.
