Trust me I have more than one type of these chalices. For me none of them like high light. Jeremy (tuberider) who has the original darth maul chalice says the same thing.
Oceaninabox may just have a weird one. Too me your chalice looks more like one I have than the one he has.
Chalices are great low light corals. In nature they are found at greater depths than many other corals. In order to collect enough light they have grown a plating form to catch as much of the limited light there is at those depths.
