One of the interesting and novel features of the interior lightingis the application of Nernst lamps on a large scale to the lighting ofthe fine arts exhibit. In arriving at the decision to adopt the Nernstlamp, the art gallery officials made careful tests to determine thepractical value of its advantages in this field of lighting, namely,white quality, steadiness and economy. In addition, it was claimedthat owing to the downward distribution of the light, a great uni-formity of illumination would be secured over the wall space usuallyoccupied by an art exhibit, the weaker rays being in the direction ofthe upper and the nearer portions of the wall, and the stronger rays.

Wherethe exhibits occupy the walls exclusively, the uniformity and intensityof the wall illumination is greatly improved by the use of a speciallydesigned reflector on each lamp, similar to that shown in Figs. Iand reflector is of light, rigid construction and is fastened to as near as practicable the actual art gallery condi-tions, were attended with very satisfactory results. The plans involve the use of 1,541 Nernst lamps of different sizes,making a total of 4,780 glower units, with a total consumption of
