EVW projector lamps for overhead projectors with 250 watts and 82 volts.

Projector equipment seems to require very little maintenance other than cleaning and changing light bulbs.  One of the most common for many different brands of projectors is the EVW projector lamps.  Although the needs of computer / laptop presentation has expanded over the past decade, there are still many overhead projectors in use on a daily basis.  The need for easy visual communication makes overhead projectors a product that will be used for many decades to come.  There are a wide variety projectors which use the EVW lamp.  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 get adequate contrasts of script for overhead transparencies.

All of the EVW projector lamps regardless of the brand, have the same shape, and sometimes the exact same shape of another lamp which might have a different voltage or wattage.  These look a lot like the FXL lamp, but the wattage is higher.  That's one of the reasons they're not interchangeable.  Almost always, the voltages vary and the amount of light as well.  The EVW projector lamps are 250 watts and 82 volt.  In regards to the shape, many bulbs have the same shape as MR16 halogen bulbs, but that's where the similarity ends.   The needs of the projection equipment demands a much higher light output than a standard MR16 could ever deliver.  Another thing to remember is that the life is shorter, about 50 hours, so it's good to turn off the lamp when it's not being used.  Every minute of time you save will give you a longer usable life  and you'll be saving money. These bulbs should not be touched with your skin as the oils can react with 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 EVW as described here or FXL, DYS, ENX, FHS 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, EVW lamps are used specifically for the overhead projector that they are designed for.  Whatever type of projection lamp you have, we have one of the widest selections anywhere, so we probablt have the projector bulb you're looking for.  We have a large inventory of nearly every kind of light bulb for 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.
