Pictured is a comparison of a plasma(1) produced in the L.E.M.U.R. lab and a photo of the anomalous Brown Mountain Lights.
Joshua P. Warren explains further: "These images (Photo 1, Photo 2) of unexplainable illuminations on Brown Mountain were captured by Brian Irish using an IR camera (Infra-red). Being shot (at night) at a distance of 2.5 miles away, and using the IR technology, the colors and detailed forms of the illuminations are obscured compared to what is visible to the naked eye.
"L.E.M.U.R.'s plasmas in the laboratory were shot from inches away using a non-IR camera. This reveals the full color and form of the hovering illuminations. If the lab plasmas are shot with an IR camera, they too appear as white blobs of light."
