I agree these are superb little units! All the Thorn Alpha 4s down my road had these as did many other streetlights around Oxford. Not one was ever seen day burning! The only day burners have the NEMA plug-ins! PS have you noticed inside the cell that silver coating (like on a scratchcard) on the LDR window with a couple of scratches in it?
