Can't get PointLight2D texture to have sharp edges (pixel art)

Question

I’m making a pixel art game and I have a pixel art texture for my PointLight2D. I can’t for the life of me figure out how to get the light texture to have sharp edges (example photo, blue is the light). The edges are fuzzy and at different window sizes you can see a gap where the fuzziness is. Is it even possible to make sharp edged lights? Setting texture filtering on the PointLight appears to do nothing.
