I used them for indoor shots of large subjects. That being said, they're probably bright enough to illuminate your large objects if you have other light sources. If you are only relying on these lights to illuminate large objects (5 x 5 x 5 feet) or more, I would recommend having at least 4-6. However, I doubt you'll find a brighter light than this for less. Finally, you can buy batteries and power the light that way. Otherwise, they come with a power cord.
