The STELMAR

High Intensity

The Stelmar Spot as its name indicates, projects its light by means
of the now well known Stelmar Projection Lighting System.

In the experimental and research work spread over the last
eight years in connection with "Stelmar" it was quite evident
that one of the primary uses of this system would be for spot and
flood light work, and in collaboration with the principal Inventor '
of the Stelmar System, Mr. H. Martin, we have developed a high
intensity spot and flood lamp which we claim without conceit

to be the finest in the world.

In one respect alone it stands far ahead of others in that the whole
of the intense beam derived from the Stelmar unit can be utilised
for spotting purposes, this being done by interposing the iris
at the narrow point where the beams converge after leaving the
unit, this point being exactly 21-ins. from the light source.

By this means, instead of the iris be ing flooded with light and
therefore passing only a small portion through the aperture whe n

. the iris is stopped down, pract ically all the light from the unit

can be passed through the iris even when stopped down , to a

circle of a diameter of
vantage over the ordinary type of spot.

Further, the marvellous reception given to the Stelmar Arc has
proved to the hilt all the claims made for it by both the Inventor
and ourselves, and it therefore provid es an exceptionally strong

¾-in. - this in itself gives a decided ad- ;

source of light for spot work in view of
the fact that the Stelmar Arc responds

readily to every increasing ampere of
light , which means that a spot of any

desired intens ity can be obtained at will.

SPOT &

A study of the two illustrations in this booklet will indicate at
once the care which has been taken to make this a spot lamp
capable of easy control and provide the operator with the desired

effects that he may require. The projector is supplied with both
spot and flood condenser lenses, either being brought into
with the greatest of ease.

The quick release for the colour mediums is conveniently placed
and windows are provided .so that the operator can see at a glance
which

The gun sight objective finder is an innovation which will prove
very acceptable to the operator. For instance, if it is desired to
use the spot on the organ, the operator , by using the gun sight
indicator can train the projector on to the organ with the full
assurance that when he opens his dowser the spot will be exactly
where he desires it to be - this obviates the irritating movement
of a spot when trying to fix it on a particular object .

The balance of the projector is perfect - no matter at what angle

it may be placed it remains perfectly steady and yet can be changed

to any other position by the pressure of a

Another feature of this projector is the wonderful quality of

· the light approaching as · nearly as possible bright sunlight ; this
in itself brings out all colour values as near perfection as possible

; and furthermore, owing to the wonderful evenness of the light

. produced by the Stelmar ~ystem the operator can always be

assured of a nice, clean, even spot or flood.

Exhaustive tests have satisfied us that we are offering to the trade
a spot and flood projector which has no
equal, and which will appeal to all stage

directors and projectionists who desire
to have their front of house projection

at the highest possible standard.
