Sylvania twin tube compact fluorescent light bulbs for energy efficiency plus long life. Used in area lighting and energy saving fixtures of all types.

One of the best innovations in compact fluorescent light bulbs over the past decade or two has been the Sylvania twin tube Dulux lamp.  It's what some people call a 2 tube compact fluorescent or sometimes a twin tube fluorescent.  The reason these are so great is that it allow designers to get a very small bulb that has a great light output.  These also offer light control that was not possible with other kinds of linear fluorescent before.  The lengths of these Sylvania Dulux lamps was such that the placement in a fixture would be in an ideal position for light distribution. Since the invention of compact fluorescent light bulbs, users have been saving energy with the most efficient small light source available. They have been used in for years in small fluorescent fixtures. The Dulux twin tube is a high lumen compact fluorescent which because of its shape can be used in many areas where a lot of light was not possible before. It has been the choice for lighting applications like recessed or hallway lighting of common areas, almost everywhere! The color rendition on the lamp is very high making it an excellent choice for color sensitive areas. The diameter of the bulb is the T4 and it has two pins typically, but there are a few of them that have 4 pins.

Compact fluorescent are the smaller fluorescents you see used in almost any type of recessed light fixture that used to use an incandescent flood light bulb. When it comes to lighting up a home or office, compact fluorescent bulbs tend to be the ones chosen more often than other types of bulbs. They are chosen most often because of the great light output and good color along with energy efficiency as well. When compared to incandescent lighting, these are longer lasting, using much less energy making them a perfect choice for almost any type of lighting. There are several kinds of compact types which include the regular household base, some that are plug-in types and some short linear bulbs. 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. On a rare occasion there may be a ballast that is made for several different types such as in the case of some commercial plug-in Sylvania twin tube lamps. Most of the time though the ballast in the lamp are matched electrically and so it's good to make sure the ballast you have is the right one for the lamp you choose.  You'll find these in several wattages down to 9 watt and all the way up to 13 watts.

You can get these in almost any color you want with a warmer 3000K color or the 4100K color more like office lighting. Fluorescent lamps can come in many other colors as well and are identified by their Kelvin temperature. By definition, virtually all are full spectrum in that they contain some of all colors in their spectral range. However, the term full spectrum is primarily used when referring to those lamps that fall into the white to blue/white color temperature range. Color temperature is measured by a term called Kelvin. 3000 Kelvin would be a warm tone color, 5000 Kelvin would be a white color and 6500 Kelvin would be a blue/white color. Although there are many choices in color for the twin tube, it is most commonly found in the 3500 Kelvin or 4100 Kelvin temperature.  The typical office color is usually the 4100 and so it makes sense that these would match up to what the light color is all around the office.

With the advent of higher electrical costs, many businesses are looking for ways to save energy with lighting. Obviously, Sylvania twin tube compact fluorescent light bulbs are the perfect choice to replace higher wattage incandescent flood lamps and save energy. You will find a great reduction in your electrical bill while still getting the amount of light that you want. Keep an eye out for electric utility rebates in your area which might be available for compact fluorescent light bulbs. This is more true in commercial lighting than it is for residential as they are a larger user of electricity during the day or high demand times.  Most cases it's been used recessed downlighting or common areas where there can be a good amount of light control while retaining good aesthetics.  It causes a greater light spread and evenness of light, with a tremendous energy savings over incandescent flood light sources.
