Title

[D8332ZBJ], Letter from Francis Robbins Upton to Thomas Alva Edison, June 25th, 1883

Editor's Notes

Howell has tested 45 recently made lamps; avg current draw is 0.754A. "I have given orders that all central station lamps in future be tested for both Amperes and E.M.F. and that all taking over .80 amperes be thrown out. This will prevent any 8 x 17 getting into use. It strikes me that the tendency will be to have the bills increase in any place from this reason. Lamps using more current [---] of power economy and probably long life. The good economy lamps will give out first and leave these uneconomical ones burning." Will take 2 weeks vacation in July. "This will be the first vacation of any length I have had since I have been with you."
