It's an older style light bulb that still has many places where it continues
to be used today. For many different brands of
machines, projectors and viewing equipment, the one that has been used are the
DNE projector lamps.
These are made with a special shape which has an integral reflector and an
two post base. Because visual communication
is important it will still be available for all those older projectors for the coming years. There are a wide variety equipment
and projectors which
use the DNE lamp, and they have a similar task which is to illuminate. The main purpose
of any projector bulb 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 DNE 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. These
projector lamps are 150 watts and 120 volt. In regards to
the shape, the DNE is very unique. 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 DNE. 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. Some people have thought that you can change out the bulb inside the reflector,
but you can't, it is precision fitted for the maximum light pattern that is
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 DNE 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, DNE lamps are used in stage and studio, overhead or
slide projector equipment they
are made to operate in. 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.
