T bar lighting height

As close to the ceiling as you can get, really. Want to avoid that people look directly into beams. You need lighting stands, they go higher than speaker stands and are usually a bit thicker/sturdier to support the greater height/weight aspect. As for set-up, that is different for everyone.

My suggestion is usually to save some money to add a Fazer (not smoke!) as it will enhance the effect of ALL your lighting gear.
