Discussion on "Factory lighting" at the London Section of the Institution

MR. ANDERSON: As a fellow member of the industry, I would like to express my appreciation of what Mr. Iliffe has told us. I realise that Factory Lighting is an extremely important side of lighting, and while we have many forms to deal with I can say that this is quite the hardest side to lecture on. Mr. Iliffe raised one or two important and interesting points. I would comment on his asking you to give your opinion on whether you thought the fixed or movable focus was the more desirable type.
