I've put up an entry on my blog about mounting an LED44 focus light to the lens adapter that goes on the Ikelite compact housings such as the Fuji F810/E900 and others. The light helps the camera focus fast and you to frame quicker. This mounting option frees up both sides for use with two strobes. It does require some minor modification to the mount (re-drilling a hole on the strap).
