I'm having a real problem with those lights:
1) Main runway lights are clearly shown on the September 1943 vertical in UK Airfields of the Ninth
. (This despite AIR2/5500 which states that Contact lighting was not extant at this time).
2) They are not evident on the May 1946 vertical in Airfields of the Eighth
, (but may have been toned down / overgrown by then).
3) Haven't seen anything exactly
like the concrete plinth or the fitting itself before.
4) One very remote possibility is that they were early versions of the T2 (See POST 2
Need to establish whether it is contact lighting or otherwise. Could some wonderful person measure the overall diameter, and that of the lens please. Thanks in advance.
T2 Post war glass encased, replacement for WWII cast iron taxi-track light. 12 volt lamp at either 12, 24 or 36 watts. Manufactured principally by GEC and Revo. 8 inch diameter with 5 inch glass dome. This unit was often fitted with a lens to provide a bi-directional beam and then used as flarepath lights at 100 yard spacing on subsidiary runways of some airfields in the immediate post war period.
