For super portability I'm a big fan of the new Came TV Fresnels. We got a set of these a few months ago. Amazing quality for the price. Use cheap Sony batteries. Super easy to gel and modify with the bowens adaptor.
If you can afford it I also love the Aputure LS-1 series. Amazing build quality. Not quite as portable but could be kitted out that way. Much more expensive but also amazing value for what you are getting.
