CLEAR and PEARLVacuum and Gasfilled Single CoilSiemens Ediswan Gasfilled Lamps are filled with an inert gas whichpermits the filament to operate at a higher temperature, and consequently at a higherefficiency than is possible with a vacuum lamp. These Lamps are manufactured witha single coil filament, and their robustness, efficiency and long life, together with a widevoltage tange, make them particularly suitable for all general lighting purposes.

Siemens Ediswan Pearl Lamps give a comfortable diffused light, free of glare, thus minimisingthe risk of eyestrain.

The amount of light lost by the internal frosting is negligible.

ARCHITECTURAL LAMPSArchitectural Lamps are manufactured in Opal GlassTube, and have spiralised tungsten filaments.The caps are mounted at the side instead of the ends to enable Lamps to be

mounted end to end.

When used singly the Lamp appears as a bar of light, but when mounted end to end

a continuous line of light is produced which can be built up into an infinite number ofattractive patterns to frt into all manner of lighting schemes.

Combinations of straight and curved Lamps are ideal for outlining corridors, doorways, fascias,

etc., whilst complete circles and fancy curves are all easily assembled.

For spraying above lamps standard colours add 3/- per foot List extra.Lampholders for Architectural Lamps.

night-lights in nurseries, sick-rooms, etc.Neon Indicator Lamps are specially small diameter lamps for use as indicators on switch-boards, electric cookers, etc., to provide a visual indication that a circuit is o' LIVE ".

INDICATOR LAMPSSiemens Ediswan Pilot and Switchboard Indicator Lamps are used on control panelsand various other installations where the visible light output has to begreater than that of a neon indicator. The Switchboard Indicator Lampis also suitable for use in conditions where the lamp is subject to vibration.

REFLECTOR FLOODLIGHTSThe Reflector Floodlight provides a beam having greater dispersion than the spotlight

lamp so that the light can be projected on to larger areas, such as

hoardings, exhibition displays, blackboards, etc.

The following tables are given as a guide to the performance ofSiemens Ediswan Reflector Floodlights.As a typical example, if a 150 watt lamp is mounted at a distance of 10 ft.from the area to be illuminated, the maximum intensity at the centre of the circlewill be of the order of 12 lumens/sq. ft. whilst the intensity at the circumferenceof a circle of a diameter of 2Oþ ft. will be not less than 2f lumens/sq. ft.

ED I SG I{AR.G E'LAIVI P:S

Siemens Ediswan research into gas and vapour discharge

lamps has been responsible for much of the rapid development in

this form of lighting. These lamps vary widely in design

and manufacture, depending on their type, size, luminous output

and application. For some types of lamp we employ advanced

automatic quantity production techniques, and for others we rely on

the manual skill of highly trained craftsmen. The result

is maximum reliability at the lowest possible

cost, whatever the type.

With the exception of Sieray Dual types, listed on Þage 35,

all Siemens Ediswan Mercury or Sodium Discharge lamps must be

operated in conjunction with a series choke or leak transformer

in order to regulate the current.

The introduction of this component lowers the power factor

ofthe circuit and this can be corrected to a level

satisfactory to the supply authorities by the use of Siemens Ediswan

Power Factor Correction Condensers.

Full details of recommended Control Gear are given on pages 4416.

SIERAY TYPE MA/V and MA/H LAMPSThese lamps are of the well-known medium pressure mercury discharge type and are available in 250 W,400 W and 1000 W sizes.

Type MA/V lamps are designed for burning in a vertical cap-up position. If it is desired to operate

these in the horizontal position, in conjunction with a magnetic arc deflector, then the use of lamps

having a special hard glass envelope is recommended. Type MA/H lamps are designed for burninghorizontally without magnetic deflectors, but may be operated in any position, without deflectors,

without material effect on performance.

FLUORESCENT TYPE MAF/V LAMPSWITH ISO.THERMAL BULBSThese lamps are of similar construction to the type MA/V but the outer bulb is coated on the inside

with a special fluorescent powder which is excited by the Ultra-Violet radiation from the discharge

and emits radiation chiefly at the red end of the spectrum, thus improving the colour of the light

output.

SIERAY TYPE MB/U PEARL LAMPSThese lamps are of the high pressure mercury discharge type consisting of an inner discharge tube of a

special grade of quartz mounted in an outer glass bulb which is of normal pearl finish.

TYPE MBF/U FLUORESCENTIn these lamps the internal surface of the outer bulb is coated with a fluorescent powder which converts

part of the radiation in the ultra-violet region, a characteristic of mercury discharge lamps, into visible

radiation, thereby improving the colour of the emitted light. As a result of continuous research and

development we are now able to offer Sieray MBF/U fluorescent lamps, in the 80 w. and'125 w. ratings,

having the same size bulbs as the normal MB/U lamps. In these lamps the use of a new fluorescent

powder for coating the bulb results in the emission of more radiation at the red end of the spectrum

and the lamps give considerably improved colour rendering.

STERAY SODTUM LAMPS TYPE SO/HThese lamps consist of a U tube of special glass containing metallic sodium which is vapourised bythe arc initially established in a rare gas at low pressure when the lamp is switched on and to enablethe necessary operating temperature to be maintained, the lamp is enclosed in an improved detachablevacuum jacket with protected end cover.

45 and 60 watt SO/H lamps may be burned at any angle between 5'above the horizontal, cap down, tovertical, cap up. The 85 and 140 watt SO/H lamps may only be burned between 5" above horizontal,cap down, to 20" below horizontal, cap up.

THE NEW SIERAY LINEAR SODIUM LAMPApproximately 3 ft. in length and fitted with the standard Bi-pin cap at each end, it is not unlike thefluorescent tubular lamp in outward appearance and, in fact, the control circuits of both are similar.The secret of this amazlng lamp lies inihe unique design of the special inner arc tube which, replacingthe conventional " U " shaped tube, makes possible a significant increase in light output.

BURNING POSITION-HORIZONTAL, or up to 20o from horizontal.SPECIAL NOTE : When fitting the lamp, it is important to ensure that grooves of the inner arc tube lie in the

borizontal, and not the vertical plane. The lamp is manufactured with the bi-pin caps so orientatedthat the correct positioning is obtained when used with standard tombstone bi-pin holclers.

DISCHÄ.RGE LAMPS ARE NOT SUBJECT TO PURCHASE TAX

45

Capacitors'fhe regulations of most supply undertakings require that all equipment installed on their mains shall

have a reasonable Power factor.

The introduction of a choke coil into an A.C. circuit lowers the power factor of that circuit to a figure

;ñtr"ri"lit Uãio* the required minimum, but this can be rectifred by installing t tytlug" capacitoruórori the rirains and in páraflel with the lamp circuit. We strongly recommend that P.F. capacitors

U" ltr"tn¿"¿ in all circuitiunless other means óf power factor correction are used.

Siemens Ediswan Power Factor Correction Capacitors are totally enclosed in a welded seamless case,

complete with flexible leads and earthing terminal.

REPRESENTATIVE ECONOMY ofDISCHARGE LAMPSMercury Vapour v. Tungsten

The Table below compares operating cost of mercury vapour and tungsten filament lamps.on a

nut tui" e""rgy basis for 1,d00 houis runnïng. Lamp life is takén as 4,000 _and 1,000 hours respectively,

so that onlyîne-third of the cost of a meicury vapour lamp is included for replacement.

GENERAL NOTES on DISCHARGE LAMPSSiemens Ediswan Discharge Lamps generally, with the exception of ultra-violet and special types,

are suitable for either commercial and industrial lighting, or public lighting and floodlighting.

Characteristics may be summarised as :-DUAL For Commercial, Industrial,LAMps andPubliclìghting. Lightis

near-white colour approach_ing daylight. Higher efficiencies of lamps can beutilised to effect up to 20of economies inelectricity or to give high illumination levels atio extra consumption.

MERCURY For Industrial, StreetAND MERCURv- Lighting and Floodlighting.FLUoRESCENT r¡.vps Give up to three times more

light than ordinary lampsof similar consumption. Have long useful lives.Light is blue-white colour from mercury lamps,and crisp-white from mercury-fluorescent.

soDruM For Street Lighting, Flood-LAMps lighting and some Industrial

Lighting where colour dis-crimination is unimportant. Give up to fivetimes more light than ordinary lamps of similarconsumption. Excellent visibility is obtainedunder the yellow light due to increased visualacuity, enhanced contrasts and freedom fromglarc.

ULrRA- For the production offluor-vrolEr LAMps escence by the irradiation of

fluorescent paints or ma-terials. Emit practically no visible light. Alsoused in laboratories for analysis of various sub-stances, and in forensic science for the detectionof forgeries and examination of stains.

Each lamp is optically pre-focussed during manufacture and the special locating washer (focussingdisc) ensures that accurate focusing of the headlight is obtained without the need for further adjust-ment by the motorist. The disc also serves to prevent corrosion of the reflector by providing a sealedjoint between the bulb and the reflector. In the case of Double Filarnent lamps the second filamentis arranged to produce a dipped beam to reduce dazzle.
