Sometimes people need a higher color temperature than something like a standard 5000K Chroma 50.  That's where people turn to this lamp which has a slightly bluer color than the standard color correct lamps with a color temperature of 5765K.  Along with this, the Excella has a very high color rendition which will be helpful for people in a retail lighting environment.  For years, people have wanted color correct fluorescent lighting and one of the lamps which accomplish that today is the F40T12 Excella light bulbs.  Most people in retail store lighting situations rely on these lamps to give better color rendition that make product look great.  With most fluorescent bulbs, you won't be able to get this kind of high color rendition as you do in this lamp, they're made for better color making your environment easier to work and play in.  They are commonly used as overhead fluorescent lighting in offices because of the clean, white light they put out.  It simulates a daylight color like natural sunshine, that makes them easier on the eyes.  This is especially important for people who work on computer screens all day long.  The one thing to keep in mind is that the light output is lower than other variations of fluorescent lamps such as cool white, unless you want to use a T10 fluorescent, which would be higher light output.  Although they have a lower light output, people generally perceive these as brighter, because colors stand out more.  These typically come in the F40T12 tube which is the standard for the more common colors like cool white or warm white that's been used in offices throughout the world.  

Like all fluorescent bulbs, no matter the color, they have ballasts inside of the fixtures in order to make them work. Ballasts are available from Universal among other brands.  The ballast is important because it is specific for each type of lamp.  You can't change from one type of fluorescent to another without changing the ballast in most cases.  On some occasions, there may be a ballast that is made for several different types such as in the case of T8 lamps. But when using these F40T12 Excella fluorescent bulbs, you don't have to change the ballast, it's a simple lamp change.  Any F40T12 fluorescent typically operates on a magnetic ballast which is less efficient than it's electronic counterpart.

With the advent of higher electrical costs, many businesses are looking for ways to save energy with lighting.  There are many choices in this area right now and one of the most popular type of lamps are the FO32T8 fluorescent light bulbs with matching electronic ballasts. This combination has been a standard for saving energy and many times has electric utility rebates associated with it.  What makes them such a natural is that the sockets used for less efficient F40T12 Excella lamps are exactly the same making it an easy retrofit if increased energy efficiency is important.
