Working out 'Load' of Lights

[webpcusa]

Hi
How do you work out the 'load' of florescent lights, so I can make sure I buy the right switch?
I know that I can't use a dimmer.
I have two situations one is 7 outside lights that all use the floro bulbs and another is an office with a total of 9 floro lights.
If I add the ind'l watts everything is under the limit for the z-wave switch but I know at startup there is a greater load.
Any help appreciated

Ignore the startup.

Florescent lights don't have nearly the initial surge that incandescent lights have, and most manufacturers have taken that surge into account.

So I just add the wattage of the tubes/'globes'?
