Not unless you really really desire it.  There are a few reasons I do not bring dancefloor lighting.

You don’t want your DJs wedding setup to look like a high school homecoming.  This is an adult event – not an 8th dance.  The venue is going to look great and your DJs setup should compliment the room.  Lighting up a dance floor requires that the lights are hung in the air so it projects over people.  Well that is awful ugly for a wedding don’t you think?  People walk in and see a bunch of light fixtures by the DJ junking up the place.  No good.

Aesthetics are not the only thing saved by the absence of dancefloor lighting.  Great moments captured by your photographer of people having fun are completely ruined.   You have these spectacular candid shots of people letting loose and having a ball only to be ruined by random dots of color everywhere and all over everyone.  Huge disappointment.

That is where uplighting creates an elegant and fun atmosphere while being unobtrusive in your pictures.
