Manufacture of Electric Lamps in RUSSIA: Test Results,
at a GUM Store in M0S00W purchased some electric
lamps which have subsequently been tested with the results given
hereunder.
2, Four of the lamps, marked on test A, B, C and D were nominally of
82 watts rating; one., marked E, was rated at 150 watts and tvto.marked F and G
were nominally 15 watt fluorescent tubes. Lamp "A" has been made available for
further study,
Filament Lamps A.B.C.D and E,
a) Lamp "A" 220V, 8211', Clear Coiled Coil
Mounting Very bad, coil pitch uneven due apparently to
stretch on mounting. Coil is out of one loop
and this defect was present when lamp was purchased.
Loops appear hand-made and badly inserted. Nickel
lead wire badly bent and distorted,
Capping Wire exposed in top contact. The side wire has been
are-welded but is now disconnected, As in the other
lamp of this type the copper lead to the centre contact
appears smaller in diameter than that to the side,
b) Lamp "B" 220V 82;T, Pearl Coiled Coil
Sealing'-in Bad shape top appears to be blown out,
Capping Soldering had been used instead of arc-gelding for the
side contact, but the finished Job is poor in appearance,,
Cap appears to be zinc-coated steel,
c) Lamp "C" 220V, 8Z7, Clear Coiled Coil
Mounting Very bad, Coil pitch very uneven due apparently to
/stretch,,.....

stretch, Supports-
upports pen ed nted but the advantage of the 25X1
construction completely wasted by too narrow lead spacing
and insufficient angle of support. Clamps badly made,.
Cam Crooked, Top soldering poor, Wire exposed, Cap
appears to be zinca#coated steel. Cement appears under-
baked and has run into the well, The side wire is arc--
welded. No evidence of fusing although the copper lead
to the centre contact is smaller in diameter than the
other, (Accidentally broken).
d) Lamp "D" 220V, 82W. 900 lrns. Pearl Coiled Coil
Sealing-4 Bad shaped top, blown out.
C appin& Soldering has been used for side contact - appearance
is fair. Cap appears to be zinc-ooated steel.
e) Lamp "E" 22OV. 150~1, Internal White Finish Side Coil
Sealing-in Slightly blown top.
Capp Soldering used and the appearance is satisfactory.
The cap seems to be zinc-coated steel,

5. An expert in lamp manufacture has coi.u,iented "The general quality
is so bad that one wonders whether they are really representative of Russian
manufacture, yet the manner of their purchase suggests that they must be, It
is interesting to note that coiloddooil filaments are usedt ir.iplying a good
quality tungsten and competent metallurgy and wire-drawing techniques., quite
out of keeping with the quality of the finished product."
