In this episode of LIGHT TALK, the Lumen Brothers (and SISTAH!) discuss everything from Chromatic Aberration to Cats on Roombas.  Join Anne, David, and Steve as they pontificate about: Why some women use male names to "Fit In"; Elizabeth Warren in David's Back Yard; PAR alternatives; The VariLite VL800 series; LED's and Tension Grids; The Skittles Defuser; Who is more intelligent... an Architect or a Labrador Retriever?; The Roomba 2020; Holograms on stage; and Date Night at Home Depot.

Nothing is Taboo, Nothing is Sacred, and Very Little Makes Sense.
