I want to tap into one existing light in the middle of the loop and run outdoor-rated flex out and branch out to about 8 CFL outdoor fixtures.

The CFL's that are equivalent to a regular 75 watt incandescent are 18 watts, so 8 x 18 = 144 watts, if I convert the existing ten 60 watt bulbs to CFL's as well then I'm looking at 140 watts (they're 14 watt CFLs), and thus about 284 watts total, or around 2-1/4 amps, plus voltage drop on about 300 feet of outdoor wiring. It looks like I'll be well under the load rating of the 15 amp breaker. Any thoughts? Are my assumptions correct?
I'm no electrician, but are the new fixtures designed to only accept the CFLs?

If you are using standard flood light fixtures that can support standard flood bulbs is it acceptable (code), or advisable to have a circuit that could be overloaded by someone simply swapping the CFL bulb (18 of them, if I'm understanding your description) with larger (100+ watt) bulbs?
