| X.3362 EFC {E. Fowler Clarke - Electrical Engineer} 5/T21.1.21. To Wd {Mr Wood / Mr Whitehead} /Ms. from EFC. {E. Fowler Clarke - Electrical Engineer} X.1114 RE HALF WATT LAMPS. X.3362 You will remember enquiring for us about Sept. 1919 as to whether 12 volt half watt lamps of lower wattage than 24 could be obtained from (a) The Ediswan Co. (b) The G.E.Co. (c) The B.T.H. Co. and in each case the answer was in the negative. Recent correspondence with the Ediswan Co. shows that the position so far as they are concerned has not changed today, but since Mr. Royce seems to expect that such lamps can be obtained, we would like you to again have it confirmed from these other two Cos. that such lamps cannot be manufactured.
