Re: CFLs wattage in fixtures
^^^What they said. However, if it is an enclosed fixture, be sure that the CFL is rated for installation in an enclosed fixture. Many are not.
Installing a CFL that's not rated for an enclosed fixture can cause the CFL to overheat, damage its internal components, and fail prematurely. (In spite of overheating, it probably won't be a fire hazard.)
LED bulbs are much better than CFLs in pretty much all respects, except bottom-line price. However, the life expectancy is much greater, meaning the total cost of ownership for LED bulbs can be less than for CFLs. (And if you're in a commercial setting where you are paying someone to change the bulbs, LED can even have a lower TCO than incandescent.) Like CFLs, some LEDs have restrictions on installation in enclosed fixtures, as with the current technology LEDs produce about the same amount of light and heat per watt as CFL, though I have confidence that will improve.
LED bulbs in a 75W equivalent can be purchased for somewhere between $10 and $20 each. I think that if you can stand to pay the premium, you'll like the LED bulb better.
