The improvement applies to the 20-watt and 40-watt white and daylight fluorescents, the types in greatest demand. Old and new values for initial lumens per watt are given by Westinghouse as follows: Lamp Old New 20 Watt WhiteInitial Lumens 860 920 Initial Lumens per Watt .... 43 46 20 Watt DaylightInitial Lumens 760 800 Initial Lumens per Watt.... 38 40 40 Watt WhiteInitial Lumens 2100 2320 Initial Lumens per Watt .... 52 58 40 Watt DaylightInitial Lumens 1880 1920 Initial Lumens per Watt.... 47 48 Mr. and Mrs. E.

They brought their new car with them and will motor to Southern California. ADVISORY COUNCIL (Continued from Page £-14) ing alike with respect to maintenance, and the same must be true also of other materials. For the variation in the experience of the experts is enormous and startling. Among members who favored acoustical plaster, some have found that any cleaning at all destroys its appearance; and some, that it can be cleaned without harm for 15 years. Similarly with fabrics; one member declared that cleaning destroys their appearance within a year or two; another that they can withstand cleaning without harm for seven or eight years. Perforated tile fares better in this respect; members who favor that material find it can be cleaned without harm from 15 years to indefinitely. Painting In the matter of painting acoustic surfaces (other than fabrics, of course) the members placed very little reliance on paints of the ordinary kind. One did note that "non-sealing flat wall paints, without a primer underneath" can be used satisfactorily on acoustic plaster, and another that "perforated tiles can be painted with E-29 a minimum loss of efficiency." The great majority, however, were opposed to any paint in the conventional sense of a pigment dispersed in a drying oil. "Water paint material should be used and lightly brushed on." "A non-bridging paint that will stain the fibres, not bridge across the surface." "Water color." "Water color. Thin enough so that the surface is not sealed." "Very thin dye color with no pigment." "Water color paints or non-bridging lacquer." "Non-bridging lacquer." "I've seen improper paint used and it ruined the surface — closed all the pores," one member added. As for how often it is possible to repaint without loss of acoustical properties, provided the right paint is used, two members thought that if sufficient pains are taken it should be possible to re-paint "almost any number of times"; and on the other side, one held that any painting at all impairs the acoustical results to some extent. The majority seemed to consider 3 to 5 re-paintings to come pretty close to the practical limit. A New Six Tube Rectifier The result of the very newest scientific developments. In single and twin type models — achieving a new high standard in three-phase full wave rectification. Built in remote control relays with provisions for operating spotlights.
