High light output and longer life, that's why many designers have
incorporated the ENH projector lamps for many kinds of lighting applications.
There's always need for an adequate amount of light to clearly present your
ideas. Although the needs of computer presentation has exploded over the past decade,
there is still a need for a manually interactive forms of visual communication. This need for easy visual communication makes it something that will
be used for many years to come, because it's still relatively inexpensive and
easy to use. There are a wide variety projectors which
use the ENH 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. Another feature of these lamps is
the excellent beam pattern that fills out the screen evenly.
All of the ENH projector lamps regardless of the brand, have the same shape, and
there are quite a few lamps that have 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 ENH
projector lamps are 250 watts and 120 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, but the ENH has one of the longer hour ratings than most
others, a full 175 hours average rated life. 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 ENH as described here or FXL, DYS, EVD, ELH or
something similar to that, you get the idea. 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, ENH projector 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 a better quality bulb. 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.
