What type of lighting will produce the most visible beam in daylight?
I am trying to create a certain special effect for an art project in which a cylinder of light appears in a well lit room and people can “step inside” this cylinder of light. I was going to use several green laser pointers arranged in a circle, pointing down from the cieling but laser beams aren’t visible unless there is smoke or dust or other particulate in the air and that isn’t feasible for this room. Is there any type of lighting that will produce a visible beam effect in a normally lit room? Maybe high intensity LED lights? Will lasers that are more powerful than pointer lasers be visible without introducing particulate into the air? Special lenses? I can ask participants to wear special glasses with filters if there is a type of light whose beam will be seen in a well lit room when someone is the filters.
