[X154A5AT], Letter from Uriah Hunt Painter to U.S. Senate. Sergeant-at-Arms, William P Canaday, February 1st, 1886

Editor's Notes

Have had charge of Edison Electric Light Plant (120 lamps) for Congressional Record Composing Room since it was installed 18 March 1882, and of the enlarged plant for the composing and press rooms 580 lamps, since July 1884.###Have found the Edison dynamos always reliable.###Edison central station dynamos have been running continuously in New York and Milan for over three years, proving the system as reliable as gaspipes; Edison isolated system under one's own control is preferable to remote source of gas supply,###[Gives statistics on running of the plant]; average life of lamps 1126 hours; cost per lamp per hour--67/100ths of a cent; gas costs 95/100ths of a cent per lamp per hour.###had no experience running Edison system until it was put in printing office, but have had no trouble running it; by carelessness, though, operators could be injured.
