I put a 75w equivalent CFL on a scope with a current probe, looking at
the wave form.
This is what it looks like

Those spikes are almost 2 amps so this might average 33w but it is not
that simple. I assume this is also a very reactive load so if you
opened a relay at or near peak, it could get pretty ugly

I have the B version of that scope. What are you using for the current
probe ? I may want to look into getting one.
