A 15 watt compact flouresent bulb and a 60 watt standard bulb reportedly give out the same amount of light. So the flours uses 1/4 the energy.
If you have a watt meter, wire it in series with the flours bulb, energize and take a reading. Do the same for the standard.
If you have a light meter, measure the readings for both. If the light output is the same, it should be your proof.

measure the Voltage across the bulb and the current in a simple series cicuit.
then use P = VI to calulate power in watts.
The Flourescent bulb should use less power, this is because the filament in a normal bulb works by having a very high resistance generating a lot of heat energy which is an unwanted energy conversion making it inefficient.

The CF bulbs, by a large margin. Why would you have to "prove" this, it's common knowledge. The ratings are printed right on the package.
In fact, California has actually proposed banning the incandescent bulbs.

Cf s do. Nearly every one of them in my house is cf. But bathroom and reading area has incandescents available for better? more useful spectrum when needed.
How to prove electrical savings.
Just run every light with one type and watch the meter spin.
Lowest electric bill $22. Highest for last year $70.
12 times 50 average equals $600 for year electric.
Less bills less work. less work more time to invent.

flourescant is better energy conservation but doesnt make a complete spectrum of light, which is why the light from them always look kind of odd. incadescent will cost more money but make a full spectrum of light. i would suggest combing one of each in fixtures where there are two sockets, and using whatever is apropriate in the other. if your only concerned about being efficent than go flouresent all the way.

The compact fluorescent bulbs do...that's the whole point of switching...they use 1/3 or less watts...
13w instead of 75 or 100!!

compact fluorescent bulbs.
our light bill went down 40 dollars just by turning off lights when were not in the room.

The fluorescent wins hands down

Keeping them turned off saves the most energy.
