Lighting

108 industrial LED fittings (horticultural) 240v.
only have 3 phase and earth in building panel.
question - can I arrange the lights in 3 rows (36) join the 1 end of each row together (star config) then feed each line with a different phase. E.g like a star motor winding.

I don't think its a daft question, it is a logical conclusion to make without further info.

If the LED power supplies put any harmonics into the neutral then you will need a neutral I think. Harmonics don't cancel in the neutral.

what about a 415v delta to 415v star transformer?

That'll do it!
