DYS projector lamps for stage and studio or overhead projectors with 2 pins plus 600 watts and 120 volts.

This lamp has been one of the perennial favorites of engineers in many types of specialty lighting applications.  The base of DYS projector lamps have a two posts or connection points that have a slightly different diameter for each one.  That makes it impossible to put them in wrong or to use them in projector they're not designed for, which has frustrated some people in the past.  It's been one of the most common types of projector lamps because of it's high wattage.  These are made with a special shape which resembles the DYP lamp except that it has linear posts, not tabs.  Because visual communication is important and stage lighting has special needs, these lamps will probably be used long into the future.  There are a variety of stage equipment and projectors which use the DYS lamp, and they have a similar task which is to illuminate.  The brightness, as most people call it, needs to be adequate for dramatic presentations as well as simple overhead presentation viewing.  The DYS lamps are not only used in projection equipment, but also for stage lighting applications as well.  One of the reasons they're used in studios or stages is that they have a color temperature of 3200K which is desired by most production companies.

All of the DYS projector 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.  Almost always, the voltages of projection lamps are different and the lumen output as well.  The DYS lamps are 600 watts and 120 volt and are a replacement for the older BHC or DYV.  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 DYS which has a ceramic base.  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 75 hours, so it's good to turn off the lamp when it's not in use.  Another caution is that these bulbs should not be touched with your skin. The skin oils can react with the glass and there can be some reactions which will shorten the lamp life.

Still another thing to remember 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 DYS as described here or another type with the letters ENX, FXL, DAY, 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.  The DYS has been specified throughout the world and there are so many different kinds of equipment that it could get confusing.  But as long as you stick with the three letter code, you will get the exact bulb you need.

In summary, DYS projector bulbs 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 you need help identifying a projector bulb, our customer service representatives can help you determine what you have.
