The latest invention from Sylvania is the Pentron circline fluorescent light bulbs which deliver the most energy efficiency in a circle of light.  These have been incorporated into many new types of light fixtures in conjunction with a larger energy saving program.  They are available in 22, 40 and 55 watts which make them a great replacement for many types of high wattage incandescent.  The T5 refers to the width which is 5/8 of an inch in diameter.  Another plus about these lamps is the improved color rendition that they provide.  You will see colors more vibrant under these lamps and the color temperatures available are the 3000K, 3500K and 4100K.  This means that fixtures they're used in will match up with other similar colors in an office or architectural lighting sense.  The grade of the phosphor is the same as an 800 series Octron or T5 linear fluorescent tube.  That is one of the highest grade of phosphors for general lighting and does the best job to get the quality of color you want.  The product code that you may need to provide would be something like FPC22, FPC40 or FPC55.

Circline bulbs in general are probably one of the most used fluorescents in the history of lighting over the past decades.  In the past, before the Sylvania Pentron circline, circline fluorescent bulbs were probably the most "compact" anything you could buy.  They were more energy efficient than incandescent lamps and were reasonably priced as well.  Now with the advent of smaller compact lamps, these bulbs are being replaced in many architectural and commercial applications.  They are an option for home users as many residential fixtures still use these because of their low cost.  We stock the Sylvania and Westinghouse brands in all available wattages with the product being by a number such as FC8T9, FC12T9 or FC16T9 just to name some of the more popular sizes.  These numbers refer to the diameter of the circle and the T9 references the diameter of the tube itself.  They are available in T9, T6 and the newer, more efficient T5 which are electronically ballasted.  The T6 are unique to one manufacturer which is TCP and they are the one people are using in floor lamps made by TCP also.  These are the most common types that are installed in buildings across the country, but the Sylvania Pentron circline is the next phase for this type of lighting.

When it comes to lighting up a business, these new T5 circline fluorescent bulbs are what architects and engineers are specifying for many new fixtures.  They are chosen most often because of the great light output along with energy efficiency as well.  As with all fluorescent bulbs, they rely on ballasts inside of the fixtures or units to make them work. 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.  This is especially true with Sylvania Pentron circline light bulbs, they almost always have an exclusive ballast for each lamp.  The ballast is always electronic and has low harmonic distortion with full light output. 

Remember that there are several wattages of Sylvania Pentron circline bulbs and keep in mind that we also stock all the larger or linear types of T5 fluorescent lamps used in commercial lighting too. Whatever type you choose or have, you will be saving energy while getting the most light you can for your money. We have a large inventory of fluorescent bulbs for nearly every type of light fixture in the field.  If you need help identifying a bulb, our customer service representatives can help you determine what you have.
