I see why he's asking. Probably using it as a door alarm with re-enforced doors blocking direct light emissions and on a low setting it can be setup as a warning alarm for unwanted visitors on tekkit servers without the obvious pressure plates being used. I've got a similar setup for my treasure room that alerts me when someone enters and a simple circuit to keep the hidden warning light powered till I shut it back off again.
