It could be one of the more unusual lamps for many different applications of
projectors and what makes it different is the base. The base of DYP
projector lamps have a couple of tabs or connection points that don't really go
into a socket, rather they make a flat connection instead.
These are made with a special shape which resembles the DYS lamp except that it
has posts. 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 DYP lamp, and they have a similar task which is to illuminate. In fact, some companies who make
lighting equipment have exchanged bulb types for greater light output while trying to
get better bulb life. The brightness, as most people call it, needs to be adequate for dramatic
presentations as well as simple overhead presentation viewing. The DYP lamps fall into this kind of description, although many designers are
moving away from it to better lamps as far as the bases go.
All of the DYP projector lamps regardless of the brand, have the same shape.
That's one of the reasons they're not interchangeable with other types of
projection lamps. Almost always, the
voltages of projection lamps are different and the lumen output as well. The
DYP lamps are 600 watts and 120 volt. 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 DYP which has a ceramic base with two
buttons on the bottom. 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 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 DYP as described here or another
type with the letters ENX, FXL,
DAY, DYS, EVD, 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 have two of the best manufacturers of all
types which are Sylvania and Eiko.
In summary, DYP projector bulbs 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
representatives can help you determine what you have.
