In all the different variations of stage and studio bulbs, there are some
which have a very specialized application. That's probably the case for
the EFP lamp. It's a little confusing sometimes, with all the choices of projection or
viewing equipment,
to find the exact bulb you will need for replacing your old one. There are
many types, but only one which is designed for the projector you have. One of the
more special lamps for
projectors or illumination is the EFP projector lamps. With the advent of
computer presentation equipment increasing over the past decade, there are still many applications
that require a manual operation and interaction. They need to perform the
simple task of of projecting light on a wall or screen. There are a wide variety projectors which
use the EFP lamp, and they don't all look at all the same or have the same
function. The EFP is also used in some types of machines that have a
viewing component for quality control as well. No matter what kind of
application you have, you'll find that there are certain things you should look
for when identifying your projection lamp.
All of the EFP projector lamps regardless of the brand have the same shape
which is a MR16 shape, and on occasion, 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. The specifications
of wattage and voltage are completely different and although they might fit in
another projector, you'll find it won't work properly. The EFP
projector lamps are 50 watts and 12 volt with a 3400K color temperature.
Another thing to remember, because these have a high light output, that usually
means they have a much shorter life. The life is shorter, about 50 hours,
so it's good to turn off the lamp when it's not being used.
Here's something to remember when replacing these type of lamps, they are
identified by a 3 letter code on the bulb. You'll see it somewhere
on the back, the base or the top if it's more like a bulb as opposed to a reflector type
lamp. Sometimes you'll see the code as EFP as described here or FXL, DYS,
ENX, DYS, ELH or
something similar to that, you get the idea. It's just a code, but it tells
everything you need to know in finding the right lamp. 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. We have found that the quality of these
is superior to almost anything else on the market. The beam patterns are
very solid which mean that you will have an even illumination making the
presentation better.
In summary, EFP lamps are used specifically for the overhead projector or
equipment they operate in. Of course, you will need
the correct voltage and capacity
for the projector bulbs that you intend to use, so if you're not sure, check the
specifications. Whatever type of projection lamp you have, you can get
what you need while getting the best quality brand for your money. We have a large inventory
of projector bulbs for nearly every type of lighting application in the field. If
