I belong to a camera club that puts the prints to be judged on a large tackboard (I don't know the correct term) on the wall of a public building. At present the prints are lighted by a couple of bulbs normally used as floodlights in ceiling sockets of rooms. The bulbs are in sockets clipped onto portable stands of the kind that might be used for cheap photofloods. The light is tungsten and not very bright. The club can to afford a few hundred dollars to provide better lighting, but none of us know what sort of devices we should buy. We'd prefer to rent some to try them for the first time. Any ideas?
