I asked him if the manufacturer offered units with red LEDs. He intimated they did but to import them he'd have to buy an entire shipping container's worth. He said he "invented" the filter as an easy-to-use and inexpensive solution.
He charged me $15 for the light and $2 for the filter. Batteries (two CR2032s) included!
I just might mimic his filter with a couple of additional sheets of red cellophane, so to darken the bright light produced. I will also make them a little wider, so to block extraneous white light.
And I just might contact the (local) manufacturer...
