The light output is really good. Unfortunately I had to send them back as they are a bit bulky for travelling. Too many pieces to assemble and a lot bulkier than I expected. A battery would be easier. I used them for a headshot session and really liked the results. Basically I got them because of the softbox option. Most LED lights are for videographers and I wanted something for portrait photography so the light needs to be softer. However, I would recommend them. The build quality is excellent, the light output is excellent.
