Certainly one of the smallest fluorescent light bulbs available today, the F4T5, has been used for lighting up very small spaces.  They consume 4 watts of energy in a linear shape making them ideal for many types of tight applications.  Because of their small size, only 6 inches long, they've been used in specialty lighting and sometimes some battery operated lighting.  The F4T5 is the standard cool white or warm white lamp in most cases, but they are also available in daylight.  The daylight color gives a more natural light similar to natural sunlight.  The color temperature of the daylight version is 6500K, it's whiter than either the cool white or warm white and would be put in the category of full spectrum lamps.  As with all fluorescent bulbs, they rely on ballasts inside of the fixtures in order to make them work.  The ballast is important because it is specific for each type of lamp, especially the F4T5 bulb.  You can't change from one type of fluorescent to another without changing the ballast in most cases.  We have this bulb available in one length and they are sometimes labeled as F4T5CW or F4T5WW or even F4T5D.  The "D" stands for daylight as was mentioned before.

As previously stated, F4T5 light bulbs have been used in many types of lighting which includes some things that are much smaller.  A popular application are small hand held trouble lights, battery operated flashlights or other types of machinery which require a specific size light to illuminate a certain area.  These could be special types of industrial machines or specialty lights, but mostly it's for illuminating areas which are usually tight and are hard to reach.  For some time in the lighting industry, exit signs used this lamp in side-lit exits or as a retrofit energy saver.  The F4T5 is really an older form of technology and are being replaced by other fluorescent twin tube or PL type lamps, but it doesn't mean that there aren't many installations where they've been used.  We have them in the popular colors including cool white and warm white.  If you have another color other than these two, please call us for availability, we probably have those too.  So no matter which F4T5 light bulbs you have, we will have what you need.

Because it's still very pervasive in many types of lighting across the country, we make the F4T5 fluorescent light bulbs a regular part of our offering. It's still being sold in some new fixtures for home users and those battery operated fixtures talked about earlier, so there will probably never be a time when these will not be in use.
