    60 degrees :p

    I joke, but this is the truth, you need to ask what is the spread at a given distance. For example 12" inches from the light a 60 degree light cone covers 13.9". 20" from the light, 23" etc... Of course not all of this are will provide good PAR, that's just the theoretical coverage assume even illumination which you won't get in reality. The center will be brightest and it will dim towards the edges. Visually you probably won't see this, but your corals will be effected by it. The center may be quite bright to certain corals, so take that into consideration.

    The orphek par38 were supposedly dimmable, though I've never actually seen anyone use a dimmer with them.

    Anyway, back to the OC Reef light. :)

    I wonder why we don't see any dimmable par30s? Like for picos?
