Jennifer recently asked about lights bigger than small flashes. She said:
I'm seeing many FB posts in RE Photography groups where many RE photographers are starting to use more powerful flashes (N-Flash, Profoto B1, Flashpoint Streak Light etc.) I do feel that I could use more power than I'm getting from my speed lights and would love to hear some pros and cons from those who have made the switch or added these big guns to their bag of tricks. I use a Canon 5D Mark III as my main camera for RE.
My take on this subject is that for standard real estate photography the bigger flashes will work but can get by without them. A great demonstration of this is that Wayne Capili uses this kit for real estate shooting and these are the results Wayne gets. It does take some learning to get to the point you can get the results Wayne does with a few small flashes but it's well worth the effort to learn the technique.
One N-Flash in it's carrying case (see photo above) without a stand is bigger and weighs more than Wayne Capili's entire real estate kit. Why would you want to carry around more gear than is required to do the job?
So who uses big lights and what are the pros and cons?
