F6T5 fluorescent light bulbs for many kinds of lighting.

The F6T5 fluorescent light bulbs are commonly used in many places where a lot of light is needed in a very small space. The length is 9 inches and the diameter is only 5/8 of an inch and that makes it possible to use the in very small areas. It's most often operated on a magnetic ballast which has been in use for decades. The small package still creates a lot of light for many types of visual tasks. The F6T5 fluorescent is not an exclusive to any manufacturer, all the major lighting manufacturers have made them including GE, Sylvania and Philips plus many other smaller makers. Some of the available colors are cool white, warm white, daylight and even black light. Generally speaking the lower the color temperature, the warmer the color of the lamp, in other words, more yellow. The daylight is 6500K and is to be like natural outdoor daylight, it's a very white color. People use this type of light for SADS and other kinds of ailments sometimes called "winter blues". The 4100K is typically the color used in office lighting.

If you have a fixture that doesn't have the lamp in it and you're unsure about the lamp itself, then open the ballast cover and check the label. All ballasts have a label that identifies what fluorescent lamp is the one for the ballast. The ballast is an electrical device that starts the fluorescent bulb with a higher voltage then goes to a lower operating voltage after the initial start. If you see a new lamp that won't light or flickering on and off, then you probably have a ballast issue and you probably need to replace that as well.
