Genaray SpectroLED-14 Light
When wall outlets are not available, this light can be powered for a little over an hour using 12V batteries (not included). It attaches easily to a light stand (not included), swivels, and accepts standard umbrella-style modifiers. The 13" size is small enough for portability but large enough for good coverage of an individual for film interviews or fashion photography.
It requires AC power to run (AC cord included). You may also run it off of 12V batteries (not included).
