Title: [D8206B], Letter from Electric Engine Co to Thomas Alva Edison, February 3rd, 1882
Editor's Notes: Would like to know how much candle power would equal the same light on a clear day for photographic purposes. {TAE replies: "Incandescent Lights provides light of such low infractibility that they do not act with any degree of prominence on the nitrate of silver - and therefore arc light would be the only E L suitable for photographing"]
