Polarized ring light source

Recently I saw this tweet from Andrew Zonenberg where he shows a comparison between a regular ring light versus one with a polarizing filter in front of the light source and the objective lens. And the difference in terms of reduction of reflection and clarity is night and day.
But after seeing the price tag of 615$ for the ring light source I said to myself: “You’re a cheap ass, you can do this cheaper”

So I went shopping on amazon and bought the cheapest LED ring light and polarization film with shipping by amazon for a grand total of 47$. Three days later these two things showed up:

I used a paid of dividers with a scalpel blade wired to one shank to cut a ring out of the polarizing film.


I removed the front transparent bezel since if would have negated the effect of the polarzing film
