Narrow/pinpoint lense for Prime hd?

[DaneGer21]

I was wondering if there was a type of lense I could put in front of/over a prime hd to essentially direct light in one spot light a spot light.

The reason, I’d light to get a clam or two in the future and my par to the sand is only about 80-120, and I don’t really have room on my rocks to reach higher par areas.

So, I was hoping I could use a Prime hd with a certain lense to turn it into a spot light so to speak and direct its intensity to a certain spot on the sand bed.

Then via the AI app I could set up its own profile to help gain a little more par.

Make sense? Anyone try this? Thoughts?

Thanks!

I’m wondering if a lens like this would do it. A diameter of about 3”, and a focal length of about 39”. The light would be mounted 14” AWL, and a clam on the sand bed would be about 20-22” BWL, so a total of about 34-36”, which means it would be pinpointed pretty well on the clam.

Thoughts?
