Comments:Thanks to James for this lamp! Thorn's very clever concept of making their double ended 250w and 400w SON lamps the same dimensions as the 1000w and 1500w linear halogen lamps respectively. The result - a very precise and economical floodlighting system just by adding a remote gear box to Thorn's Sunflood luminaires.
