The original monitor light doesn't make the wall brighter (the Halo edition is a relatively new offering). Rather it provides a smooth intensity gradient on the work surface directly in front of and underneath the monitor. This smooth gradient is very effective at reducing eyestrain. Unless the room lights are specifically designed for optimal lighting of the workspace, they cannot achieve the same effect. In typical homes, the room light is either a single ceiling fixture or lamps (one or more), spread throughout.
