Lighting for prints on the wall

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?

Tracklighting attached to the ceiling in front of the board, with a bunch of 75W adjustable lights.
