| to where it is needed and avoid wasting light. A common situation like this is a place with a high ceiling. Here, lights can be suspended and the reflectors will reduce illuminating the area above the lights. Also, reflectors would have value where lights are mounted on ceilings that are unfinished or unpainted drywall because the reflector is far more reflective than either of those surfaces. Plus the reflector would concentrate the light and could better direct it to the work area, something of potential value even in white painted, finished garages. So you can see that the value of reflectors depends on a host of factors and needs. Also, light spreads according to the inverse square law. If you don't have a lot of light, or are working in a place without white walls, it will help immensely to reflect the light to where it is needed, rather than let it bounce around.
