Does this fit Prime freshwater?

Yes. It fits all versions of AI Prime lights.

Does the OEM diffuser cover need to be removed prior to using this aftermarket accessory?

Nothing needs to be removed from the factory light. You simply snap on this product and you are ready to go.

Which side of the plastic faces down? The pointy side or the smooth side?

Pointy side down and smooth side towards the light.

How much reduction in light intensity does this create?

15% reduction. If your light is 12 inches in height or more, lowering it about 2 inches is enough to regain the par reduction.
