✦ Synopsis

Diagram, /;i/r. 4, shows the results of test on IO0 lamps of a high-grade lamp, and illustrates what may be expected of well-made lamps.

It is to the interest of all purchasers to require lamps to conform to the one candle, 3-watt limits referred to above, by testing samples from each lot purchased, and rejecting every lot failing of these requirements.

There is no need of farther testing any lamps that fail in this respect.

In comparative tests of lamps, as many lamps as possible should be tested for initial rating--from 50 to Ioo or more. This gives a full average of results, and besides provides a sufficient quantity from which to choose lamps of the efficiency taken as a basis for the candle-power performance test.
