This U6 U-shape fluorescent has been one of the most used for office lighting requiring high illumination in a small space. They are the older style, less efficient type of u-shape, but still are being replaced on a regular basis by many facility managers. The FB40T12 fluorescent light bulbs have a 6 inch leg spacing which is exactly the same as the more efficient FBO32T8 lamps, making them a candidate for energy saving retrofit. The FB40 can be a 40 watt or 34 watt version depending on the color you choose, the cool white are always 34 watt now by energy legislation. These lamps are a T12 version which is 1.5 inch in diameter and operates on an magnetic ballast. There are many different brands of ballasts and all function to make the lamp start and continually operate, supplying the right voltage in each individual instance. They give off a great variety of colors and the color rendition is very high if you choose the better grade phosphors.

The U6 U-shape fluorescent light bulbs are made by several manufacturers including GE, Philips and Sylvania among others. No matter who the manufacturer is, they are as common in today's buildings in 2x2 fixtures as some linear types. That's because many lighting designers are looking to reduce the size of lights making them less noticeable. But because of utility rebates, these lamps are being replaced at a rapid rate, although these will still be around for a long time as there are so many installations that use them. They're easy to install and the pop in the sockets in most fixtures with only a small amount of force. They come in full cases of 12 and transport easily with excellent packaging, great for storage too.

As mentioned before, there are several color choices these come in which include cool white, warm white, daylight, 3000K, 3500K, 4100K or the 5000k which many people refer to as full spectrum light. There are appropriate places for each type of color. If you need a warmer feel that accent natural colors like wood or plants, the warm white, 3000K or 3500K would probably be the best to use. It will maintain and make those colors look even better. For offices, the cool white or 4100K has been the most popular as a clean, white light, good for all general purposes. The 5000K is really for people who want to function better under artificial light and this version of these U6 U-shape fluorescent light bulbs should work great for those who like natural sunlight.
