HFs vary alot in efficiency, manufacturers data will help but if its running 10.8 you have little choice but to go C16, 1.5 might work if the runs are not too long
Is there a formula for flourescent lighting??
Yes, you've got enough information to determine it;
10.8 / 7.25 = 1.49
12 / 7.25 = 1.65
Seems to agree with earlier posts.
What about if you use the R2 method?
I always record the highest reading.
Do the fittings not have to fused to be connected to a 16a mcb? Seem to remember havinbg to install a load of fused fittings when the circuits were 2.5/16AHFs vary alot in efficiency, manufacturers data will help but if its running 10.8 you have little choice but to go C16, 1.5 might work if the runs are not too long
The run is 10 metres mate what do you think I can easily change the wiring to 2.5mm for a c16 or change the mcb to a c10.
Just a personal preference, but checking every point ensures all current using points meet the required Zs rather than relying on a installation being perfect because one other test says all is good.

I knew it was X 1.8, just wasn't sure where it was listed.
As the others have said, check your Zs at the end of line (should be the highest) and just make sure it doesnt exceed the maximum value given for the mcb you require. (in this case a Type C)
If it does exceed that value, how about changing for an rcbo? Or reduce the earth loop impedance by adding supplementary bonding (if practical)
