Aktiebolaget Aladdin, Stockholm, made the Ideal, one of a series of Aladdin-Invert lamps,
which appears in a 1911 catalog in Christer Carlsson's collection.
The 250 cp light is fueled with kerosene from a tank (right image)
that connects to the downward projecting brass connector (middle image).
The key on top of the tank goes into the regulator below the key
and allows the air  to pressurize the fuel in a separate part of the tank.
The tip cleaning mechanism is missing (middle image).

The Primus brand was manufactured by Aktiebolaget B.A. Hjorth, Sweden.
Their Model 394/6 is an alcohol fueled variation on Model 994 (below)

and is in Christer Carlsson's collection

This Model 992 Primus harp lamp dates from 1955.

and is a close match to the original.

It was made in Sweden by Aktiebolaget B. A. Hjorth Stockholm.
The lamp on the left is in the collection of Roger Price; image by Neil McRae,
while the lamp on the right is in Neil McRae's collection.

Aktiebolaget Lux, Stockholm, Sweden, made this kerosene gravity lamp street lamp that is nearly 1.5 m tall!
Fuel from the fount at the top of the lamp travels down the small tube seen on the left in the left image.
The fuel enters a vapouriser within the globe
(seen on the right inside the globe in the left image) and travels back to the top
where the heated fuel passes through a jet and back down the lamp cylinder (mixing chamber) to the burner.
This lamp, in Christer Carlsson's collection, dates to 1909-20 and produces 700 or more cp.

Aktiebolaget Lux also made this Victoria model
which is a kerosene gravity lamp for indoors.
Christer Carlsson, whose collection this is in,
runs the lamp (right) with an upright Aladdin mantle.
The Victoria dates to the same time period as the Autolux above.

The globe is a replacement that is similar to the original.

Aktiebolaget Optimus, Upplands Väsby, Sweden

made this Model 209 kerosene burner,
this 200 cp table lamp is complete with optional shade.
This lamp is in Neil McRae's collection.

When Bo Ryman bought this Optimus lamp
it had a different globe and was a Model 250.
Bo was able to convince a workmate, who had this globe,
to trade it to Bo, thus making it a Model 250A.
This is another example of a lamp option
on a stove base.

Optimus Model 253, in Magnus Thilander's collection,
is a 200cp kerosene model
that likely dates to the 1930's.
This pendant lamp has an added heat deflector.

depending on the shade which is missing (Nils Stephenson).

was photographed by Neil McRae.

A number of Swedish lamp models were lanterns with shades added.
An example is this Optimus Model 930, which was in Magnus Thilander's collection.
The shade is original and the small can is for preheating alcohol
for the kerosene fueled lantern/lamp.
This version is 350 cp, not 300cp and is so marked.

This is a Radius Model 106A outfitted as a lamp.
Bo Ryman bought this lamp from an employee of the Radius factory
after the employee had stored it for 20 years in his basement.
This 1960's vintage lamp is in brand new condition.
The original fringe is made of glass beads threaded on ribbon
and held up by a thin wire pressed under the edge of the reflector.

Small alcohol pendant lamps, like these Radius Model 107s, were made during WWII
when petroleum-based fuels were in short supply in Sweden; the fount holds about a half pint.
The lamp has a vented filler cap so cannot develop pressure except by gravity
to fuel the generator under sufficient pressure to operate.
The lamp on the left is in Neil McRae's collection.
Bo Ryman refinished his lamp on the right to the original.

Bo Ryman bought this Radius 114 lamp
in never-used condition.

Radius Models 143 (left), 145 (center), and 146 (right) lamps
were sold by the company as options to put on the stoves
which are Models 21 (left & right) and 17 (center).
The lamp on the left is in Neil McRae's collection
while the ones in the center and on the right are in Bo Ryman's collection.
These models were probably made in the 1930's.
