Lateral file cabinets are usually between 30 and 42 inches wide and come with 1 to 6 drawers. A foot of paper is a foot of paper whether it is in a standard banker box or a lateral file cabinet. Just figure out how much feet of drawer space you have and multiply by the amount of paper you have in a foot.
The bulb is normally 25 to 40 watts. Generally, it will take 45â60 minutes for the wax to warm up enough to form freely rising blobs, when operating the lamp at standard room temperature. It may take as long as 2 to 3 hours if the room is below standard room temperature.
The standard deviation, along with a given average life, provides a way to estimate individual lamp failures. For example, consider two T8 fluorescent lamp models with an actual life of 24,000 hours and standard deviations (failure rates) similar to models 1 and 2 in Figure 8. For an office space with 100 lamps, the first lamp failures would be expected to occur before 17,300 hours for model 1 and 11,800 hours for model 2.
