I consider these studio only lights. I really wish I just invested in led lights early on. They do work great though, but to me they are not portable at all.
EDIT: I have since purchased more portable LED Lights and I take it back, I am happy I invested in these first and they are great for the studio.
These have 9 Bulbs and create some great light. We have 4 of them, mainly so we can light the background well and two for the subject and we use a smaller 5 bulb version for hair light etc.
