Title: [D8230ZBB], Letter from Francis Robbins Upton to Thomas Alva Edison, July 6th, 1882
Editor's Notes: "Regarding the formation of Lamp Co." Recommends issuing stock to present partners, then a public issue at par. "Regarding a different price for A and B lamps." "Regarding making higher resistance and greater economy lamps." "600 hours life and 12 per H.P. is a big thing to do and we are the only ones that can touch it giving 320 ohms as a resistance. My idea is, that any way for next central station, we will make a lamp requiring 140 volts while giving 16 candles and of as high economy as it is commercial to make."
