Load calculations for Fuorescent Lamps

[230V]

Can anyone advise on how to calculate the load current for 15 high frequency tube lights (116W / each fitting)...all on one circuit.

Normally it would be: I= Power/Voltage. But for dicharge lamps I think there is a multiplication factor (not the power factor..some other)

...can anyone show me the light !!!

1.8 factor
mean anything to you.

116x1.8 = 208.8

208.8x 15 = 3132w

3132/230 = 13.7amp

means a lot to me, I forgot to add it on during an exam and lost marks, still passed but those silly mistakes cost

But I bet you'll never forget again though.

i'd have thought HF fittings would have a better power factor than conventional ones but maybe i'm wrong.

Thanks guys. Thats sorted me out. I read it somewhere but wasn't sure. Much appreciated.
