The history of screen lighting7 even from the beginning, has been one move after another to obtain more and better light. High intensity projection has always produced enthusiastic response from theatre patrons, since they notice and show favorable reaction to the improvement resulting from installation of this type equipment.

High intensity lamps provide a grcatcr volume of screen light than the older low intensity lamps. This allows a clcar cut scrccn imagc to be shown in the presence of a safe and comfortable level of general illumination. Patrons entering the auditorium from the lobby find their seats without discomfort or embarrassment, whilc the lightcr contrast. between the screen and surrounding illumination adds to visual con'lfort. in viewing the picture.

A furthcr advantagc of the high intensity arc for projection is the snow white. quality of its light. Light from the low intensity arc is comparatively dull and yellowish. This distorls the hues of color features and detracts from the impression of rcalism which color is designed to create. High intensity projection reproduces all colors with great fidelity and gives a realistic quality to color features not otherwise obtained.

From the standpoint of the small theatre, the gIOne Kilowattf carbon arc ranks among the most important advances in the art of motion picture projection. It enables thc smallest theatre, at little or no increase in operating cost, to have the advantages of snow white projection light. and the rcconnnendcd level of illumination on the screen. It rcmovcs thc edge enjoyed by those thcatres

having the more expensive typcs of high intcnsity lamps.

Ono of the most important objectives in prcparing for future busincss is improvcmcnt in the quality and quantity of scrccn illumination, cspccially sincc incrcascd production in color films is cxpcctcd. No tllcatre will bc a

modern thcalrc without high intcnsity projection.

'lihc Li()ll(* KilowatU9 arc, without increasing operating cost, now allows the' small theatre to give its patrons 50 to 80 per cent more screen light, more realistic color reproduction, and a quality of picture presentation un surpassed by anv theatre, regardless of size.
