Since white light is emitted from an incandescent bulb, it contains all wavelengths in the visible light spectrum between 400 to 700nm. It also emits wavelengths in the infrared region.
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
55-watt
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
A 13 watt cfl is the same as a 60 watt incandescent. So find an led bulb that is equivelant to a 60 watt incandescent
fluorescents are about 5x as efficientso a 12W will give about as much light

A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.

Yes, if the bulb is incandescent, and you change from a higher wattage bulb to a 25 watt bulb the future growth will be smaller.
Incandescent: 10-12 lumens per watt CFL: 50 lumens per watt.

Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.
It depends on the type of bulb. Incandescent bulbs convert about 90% of the energy into heat and and only 10% is put off as light. LEDs, for instance, are much more efficient, converting almost 90% of the input energy to light. So, a 5 watt LED will convert about 4.5 watts to light, while a 25 watt incandescent will only convert 2.5 watts into light.
A 3 watt led light is not the same as a 45 watt bulb. A led light is a lot brighter.
You would need a 12 Watt flourescent bulb
