It dose what a light dose and bright with two preset brightness recargable plug in back with two batterys inside and has that regular rubber seal where in opens to keep water out . used this for youtube when working on something in a tight spot like a engine bay or under a car or someware where my lams cant get at this will. since we do car stuff and work in a quonset hut dungon and dark with no skylights so watever the studio lights cant get or will create a shadow with this shining where the camera looks looks great, I can see its function on atv's at night. and one thing i never saw it looks like a spoon but that ataches on the screws to tighten and loosen the bolt perfect.
