Abstract

In reply to yours of 21st: 70 lamps are entered for the test; Weston 20; Edison, 20; Stanly, 20; Woodhouse & Rawson, 10; I propose to make 60 measurements of each lamp; don't see how we can measure over 70 lamps; "would be pleased to make a simple duration test with preliminary metric & efficiency measurements. This would not be of scientific value but might be of use to you"; send 30 lamps & 10 sockets.
