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.
Well they are suppose to give off the same light, say in wattage, but they use less power, and generally cost more. Most LED's, have a rating to match a regular bulb.

The wattage will depend upon the type of bulb and the number of lights on the string. It will tell you on the package what each bulb requires in wattage, so you only need to multiply that by the number of bulbs in the string. so, number of bulbs x wattage requirement for each bulb = wattage requirement.
Also CFL and LED light bulbs use much less actual wattage than their equivalent wattage. It is best to look at the datasheet for each individual type of light bulb. They can vary from milliwatts to kilowatts, depending on the purpose the light bulb was intended for.
