The proliferation of projector equipment has also precipitated the need for
lamps as well. One of the most common for many different brands of
projectors is the ENX projector lamps. Although the needs of multimedia presentation has exploded over the past decade, there are still millions of overhead projectors in use on a daily
basis. The need for easy visual communication makes it something that will
be used for many years to come. There are a wide variety projectors which
use the ENX lamp, and they don't all look at all the same. In fact, some companies who make these
projectors have switched bulbs from
time to time for any number of reasons. 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 writing or overhead transparencies.
All of the ENX 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 vary and the amount of light as well. This is done by engineers
who are building an overhead to perform correctly for it's use. The ENX
projector lamps are 360 watts and 82 volt. In regards to
the shape, many bulbs have the same shape as
MR16 halogen bulbs, but that's where the similarity ends. The MR16 has a
few basic voltages and does not have the watts that are needed to produce the
light that an overhead projector needs. Another thing to remember, because
these have a high light output, that usually means they have a
much shorter life. The life is shorter, so it's good to turn off the lamp
when it's not being used. Every bit of time you save means the lamp will
last longer and you'll be saving money. These bulbs should not be touched with your skin as the oils can
react with the glass. If they
are touched, the life span of the bulb will be greatly reduced and sometimes you
might see a bubbling of the glass. In case you ever
do touch inward reflector of the lamps, wipe it thoroughly with a soft cloth.
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 the code as ENX as described here or FXL, 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, ENX lamps are used specifically for the overhead projector they operate in. Of course, you will need
projectors that will have the correct circuitry
for the projector bulbs. Whatever type of projection lamp you have, you
can get what you need while
getting the most light you can for your money. 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.
