When looking for projection equipment lighting, it makes sense to find what
what works and has the correct specifications. One of the most utilized
bulbs for many different brands of
projectors is the CLS / CLG projector lamps. The needs of multimedia presentation has
expanded over the past decade, but there are still ordinary overhead projectors in use on a daily
basis, and they use a variety of lamps. The need for easy, visual communication
will make these bulbs needed for many years to come. There are a wide variety projectors which
use the CLS / CLG lamp, and they don't all look at all the same. In fact, some companies who make these
projectors have engineered other lamps 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 CLS / CLG projector lamps regardless of the brand, have the same shape.
That's one of the reasons they're not interchangeable. The CLS / CLG
projector lamps are 300 watts and 120 volt. Something to keep in mind
about these lamps is because these have a high light output, that usually means
they have a much shorter life. The life is shorter, about 25 hours, 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
also have a silvered dome top which prevents light from going out the top of the
lamp itself. Another thing to remember is 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 CLS / CLG as described here or ENX, 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. The CLS / CLG has typically been the choice
for an extra bright light.
In summary, CLS / CLG 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.
