This will work on ghost control systems

We asked the Manufacturer and they replied: "We’ve had these units used in “haunted houses” to control some of the displays to scare people. But not entirely sure of what they are asking for."

What is the ambient illuminance rating for the reflective photoelectric sensor?

We asked the Manufacturer and they replied: "It is an IR sensor so we would say no ambient illumination."

Do they operate in daylight ? What is dark on ?

Yes, they work in daylight. The Dark-On/Light-On has to do with the relay status when the unit is powered off.
