The Watt is ameasure of electrical power. How can new energy saving bulbs put out as much light as regular bulbs with 1/4 of the Wattage?

Easily. The thing to remember is that with a traditional bulb, the wattage is only how much power it uses, not how much it converts into light. On average a 100 Watt conventional light bulb only converts about 5 Watts into light and the rest goes into heat. This makes them only about 5% efficient. This also explains why a bulb that has been on for a while is too hot to touch. So for a fluorescent energy saving light bulb to put out the same amount as a conventional 100 Watt it only needs to generate 5 Watts of light. So a 20% efficient bulb can generate 5 Watts of light and 20 Watts of heat. Hence this slashes the total wattage by 1/4.

The watt is a measure of how much power is used BUT the "Lumen" is the measurement of brightness. for the longest time they appeared locked together but newer styles & tech can do some wild things BTW a car headlight & a table lamp may both draw 40 watts but the car light will take 10 times the amperage

Because of the lumens produced per watt of energy consumed.
