What's the difference between a compact fluorescent light bulb (CFL) and a fluorescent tube?
The main difference is their size. CFL are made to fit in standard household light sockets (eg. table lamps). Additionaly, most compact fluorescent lamps have an "integral" ballast that is built into the light bulb, whereas most fluorescent tubes require a separate ballast. Both types are energy efficient lights.
How much UV should a fullspectrum lamp contain?
Just enough to support the positive effects UV light has (like vitamin D production). A too much of UV could be harmful. Viva-Lite fullspectrum lamps contain a desireable amount of UV, the exact number is corporate secret.
How can I save energy with my general lighting?
This is simpler than you might think.
Switch all light sources off when they are not used. It is correct that energy saving lamps make only sense when they are not switched on and off all the time but letting them on for no reason is not what is meant by this statement either!
Less watt means less energy consumption. Nevertheless, it is more energy efficient to use one strong bulb instead of many weaker ones.
Use indirect lighting sparingly.
Arrange work places with as much daylight as possible.

Why do I suffer from headaches from some fluorescent lamps?
That's a good question. The reason for headaches under some fluorescent lamps may be due to an older version of ballast used which creates a stronger electromagnetic field and also causes flickering in the range of 50Hz that may be very disturbing to our minds and bodies.
