A comparison of the readings taken on these two installations will show 

 a similarity which explains the dual selection of satisfactory illumination. 



The general tendency of both of these units mounted on 2i-foot stand- 

 ards is toward a uniformity which will relieve eyestrain, but with sufficient 

 variation between maximum and minimum intensity at a spacing of 156 

 feet to create a silhouette effect desired by some observers. 



The tendency of the General Electric unit is to a higher maximum and 

 higher average intensity with a greater amount of illumination from the 

 same source, whereas the Westinghouse unit produces a slightly higher 

 minimum intensity and a more uniform distribution of light. 



In the opinion of the observers, both installations satisfied in this loca- 

 tion the conditions previously mentioned as requisites of a well-designed 

 lighting system and produced effective and pleasing illumination. 



The glare due to the high intensity of lamps used in the low mounting 

 heights could be diminished by using lower candle power lamps. This, 

 however, would require a closer spacing of standards in order to get the 

 required average and minimum intensity, and because of the cost involved, 

 it was not considered practicable for boulevard lighting. 



Park and playground lighting. Experience in the lighting of our own 

 parks has demonstrated that high intensity of illumination in the parks is 

 not necessary or desirable and subsequent recommendations are based on 

 providing only sufficient light for discrimination of object. Because of the 

 winding walks and irregular features of the parks and the low-hanging 

 foliage, it is necessary to use small sized lamps of low mounting height and 

 comparatively close spacing. 



The design of the playground lighting contemplates providing suffi- 

 cient illumination for ordinary activities such as lawn games, gymnastics, 

 football practice, skating and such uses as do not require high intensity of 

 illumination. No attempt has been made to light the tennis courts because 

 of the large expense, involved and the unsatisfactory results obtained by 

 other cities. Special floodlighting equipment is desirable for bathing beaches 

 and hockey rinks. 



RECOMMENDATIONS 



Lighting equipment. All conduits, transformers, standards, luminaires, 

 and other equipment on park land to be the property of the board of park 

 commissioners and to be purchased and installed by them, under contract 

 or otherwise. 



Electric service. All electric service to be furnished by the Minneapolis 

 General Electric Company from present lines and necessary extensions in 

 conformity with plans attached.
