Amazing New Lamp

a Discovery by Prominent _ Physicist.’ '

yz has been reported that one of i. most important.-discoveries in ch. trical science has now been made by t v ‘ physicist, C. Bol. In the overseas laboratories. of the Philips Lamp Works in Eindhoven, Holland, Bol has now succeeded’ in’ ‘making a gaseous discharge lamp’ of extremely high’ bril-

liance, exceeding by far the ordinary ‘are lamp.» Whereas the brilliance of the carbon are lamp is 100,000 int. ep. per square inch the new lamp has a brilliance of no less than 250,000 int. e.p. per square inch. It is confidently expected that the new lamp will provide- more ef-. ficient lighting for projection, aerodrome, flooding, searchlight, ete. Experiments in the application of the sume principle for general lighting have resulted in the-construction of a similar lamp of lowér wattage. This lump has a very high efliciency and further developments are expected to reveal interesting ‘possibilities for general lighting. "At the same time, ‘the sodium lamp is expected to retain its position as the most. suitable lamp 4 for road lighting. .... we

We look forward with interest to further details of the new discovery which. coming on. top of the introduction of the sodium lamp, promises remarkable cevelopment in lighting practice, although, as before, the sodium lamp will tmain unchallenged for road lighting. .
