I'm looking at making a DIY ring light using multiple fluorescent light bulbs. I'm in New Zealand and we get 230-240V and an current of 10A. I know from this I could rig up to 24 100W bulbs in series onto the ring. Although it is likely I won't have more than 10-15.
Here is an example ring light.
My question is this, how should I go about grounding this circuit? I've done some physics and am happy with power and voltage equations but was always a bit fuzzy on the concept of grounding and how it should properly be carried out.
Thanks in advance!
