This is a light source that works wonders on dark rooms. Drop these in your night homes (as many as you need) and position them as needed to light up the interior or exterior of your house. It's a great scene enhancer for your night time rooms. Try it in shop along with a dark room to see the effects. PLEASE NOTE that you will ONLY see changes in rooms with darker ambiance. The effect varies depending on the lighting setting of the room it is placed in.
