How does 4 tube fluorescent work?
A four tube fluorescent luminaire is just 4 separate fluorescent lamp circuits in one fitting. Look up 'how things work' etc to see a fluorescent lamp circuit.
On your 4 bulb fluorescent only 2 bulbs come on?
On the older fluorescent fixtures a four bulb fixture required two ballasts. Two lamps for each ballast. If you have changed the tubes and it still does not work, it sounds like one of the ballasts is not working. You might want to consider replacing the ballast with an electronic one. One electronic ballast will operate four tubes. The existing end sockets can be re used but they will have to be rewired. There is a diagram on the ballast label that shows the connections. This will allow you to use T8 lamps which are lower wattage. This will save money to you in the long run.
How is a fluorescent light made?
A fluorescent bulb uses a completely different method to produce light. There are electrodes at both ends of a fluorescent tube, and a gas containing argon and mercury vapor is inside the tube. A stream of electrons flows through the gas from one electrode to the other (in a manner similar to the stream of electrons in a cathode ray tube). These electrons bump into the mercury atoms and excite them. As the mercury atoms move from the excited state back to the unexcited state, they give off ultraviolet photons. These photons hit the phosphor coating the inside of the fluorescent tube, and this phosphor creates visible light. It sounds complicated, so lets go through it again in slow motion:There is a stream of electrons flowing between the electrodes at both ends of the fluorescent bulb.The electrons interact with mercury vapor atoms floating inside the bulb.The mercury atoms become excited, and when they return to an unexcited state they release photons of light in the ultraviolet region of the spectrum.These ultraviolet photons collide with the phosphor coating the inside of the bulb, and the phosphor creates visible light.The phosphor fluoresces to produce light.A fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs. That's why you can buy a 15-watt fluorescent bulb that produces the same amount of light as a 60-watt incandescent bulb.

How many T8 fixtures can go on one 20 amp circuit?
Divide 20A by the Amps listed on the label of each fixture ballast. A T8 bulb will use an electronic ballast. They generally run 1A for four 4 foot bulbs. Try 15 four bulb fixtures per circuit and use a 20A rated switch.
How much does a 28 cubic foot freezer cost?
Cubic-Foot Refrigerators: Two-Door, Single Bottom-Drawer Freezer Models: $87.84. Side-By-Side Models: $88.68. Four-Door
Does it cost more to run four equals 25watt bulbs than one 100 watt bulb?
100 watts is 100 watts no matter how you add it up.
If I remove two of the four lamps in my fluorescent fixture to save electricity should they be on the same ballast?
Yes
Are there are drawbacks to using fluorescent bathroom lighting?
It is relatively safe to use fluorescent lighting in your bathroom. Flourescent bathroom lighting usually ranges from two-four feet in length and is an ideal source of light for your bathroom because of the low operating cost and low heat output. The light is spread evenly and with the newer designs, you dont have to sacrifice on style and appearance.
