The heatsinks came like that. Probably held some components or something. They are only 1/16 of an inch deep so a few emitters will sit 1/16 inch higher than the rest. I figured 1/16 inch won't make an appreciable difference in PAR and coverage etc. and given the cost savings of the heatsinks vs. something pristine I could live with it. It won't be visible inside the housing anyhow.
