Sometimes stage and photo studios need a higher wattage of light and that's when they often incorporate these lamps.  There are many types of lighting applications that require a certain kind of light, especially when you're talking about photography.  The way a camera makes an exposure depends a lot on the light you're illuminating with.  When looking for photography lighting, it makes sense to find what what works and has the correct specifications.  One of the most popular lamps is the EBV photoflood light bulbs.  The needs of color correct photography has always been critical, but even more important today with different kinds of equipment including digital hardware.  There are a wide variety of fixtures which use the EBV photoflood, and they don't all look at all the same.  The main purpose for a bulb like this is the light it puts on a surface, how well it fills out the area with light. 

All of the EBV photoflood light bulbs regardless of the brand, have the same shape.  The EBV lamps are 500 watts and 120 volt.  The color temperature is 3400K color is very good for TV cameras, stage as well as some camera exposure as well.  Something to keep in mind about these lamps is that they have a high light output, that usually means they have a much shorter life.  The life is shorter, about 6 hours, so it's good to turn off the lamp when it's not being used.  These also have a frosted coating which makes it possible to get the correct 3400K color which is much like incandescent lighting, only a bit whiter.  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 top if it's more like a bulb as opposed to a reflector type lamp.  Sometimes you'll see the code as EBV as described here like other types of projector or stage lighting such as FXL, DYP, EVW, ENH or something similar to that.  The ANSI 3 letter code identifies that bulb as to the shape, wattage, voltage and any other standard information.  The EBV is a PS25 shape which has a longer neck making it possible to fit in deeper can fixtures.  Unlike other types of bulbs, these have some standards across various manufacturers, the only thing that varies is quality.

In summary, EBV photoflood light bulbs are used specifically for the fixture that can handle the wattage and base.  Of course, you will need fixtures that have the correct voltage for these bulbs.  Whatever type of illuminating 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 photography bulbs for nearly every type of lighting application in the field.  If you need help identifying a photoflood, our customer service representatives can help you determine what you have.
