Are you sure you want to delete this?
Bodging something together by placing it between phases is not something I would recommend - especially as you are obviously not a qualified electrician. The very fact that you need to ask a question like that tells me that the answer is "Don't do it!"
Depending on how your lights are wired internally, yes, you can ruin them or even put the housing and lighting stands onto a phase - I've seen it done!
Sorry to be blunt - but there is nothing quite as much fun as watching someone handling a lamp and then reaching out to a scaffold pole, only to be caught between two phases and nearly killing themselves. At least some people thought it was fun because the guy in question was repeatedly told not to rig his lights that way.Back to Lighting...
