Editor's Notes
"I have been making a test of the life of 24 "NEW" 3.1 watts per C.24 C.P. lamps, and I have arrived at results, I think, will interest you. ### We run, as you know, 110 V. lamps on 110 V. circuit. ### Lamps were placed in circuit Feb'y 13?. ### 1st lamp burnt out in 11 hours ### [table of 2nd through 6th lamps follows, with hours burned] ### 7th and all are still burning 24 hours per day, which to date makes 2688 hrs." Yours truly, Frank W. Ribble, Sup't
