It's unusual and you may not run across it very often in the world of stage and
studio and projectors, but the DAY / DAK projector lamps have had many
specialized uses in the past.
These are made with a special shape which resembles and old TV tube with an
unusual base. Because the need to communicate visually
is important and stage or studio lighting has special needs, these lamps will be
an option in a number of places where nothing else will work. There are a variety of
studio equipment
and projection equipment which
use the DAY / DAK lamp. The have a high light output which and ability for
great light control because of the small filament. Many types of studio
lighting fixtures have a reflector system which needs a small focal point of
light. As well as the positioning of the filament, the brightness, as most people call it, needs to be adequate for
stage
presentations as well as overhead presentation viewing.
All of the DAY / DAK 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. The DAY is actually a replacement of the older number
which is the DAK. Many older types of applications will refer to the DAK
lamp. Almost always, the
voltages of projection lamps are different and the lumen output as well. The
DAY / DAK
projector lamps are 500 watts and 120 volt. In regards to
the shape, the DAY / DAK is very unique. 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 DAY / DAK. 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 30 hours, so
it's good to turn off the lamp when it's not in use. The color temperature
is also 3200K which makes it ideal for TV studio lighting as that is the color
that usually works best with many kinds of television cameras.
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 DAY / DAK as described here or another
type with the letters ENX, FXL,
DYS, DYP, 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, DAY / DAK lamps 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
