Non-electric lights.
Before the invention of electric lighting, the substances that provided light were oil and wax. The articles on the following pages are evidence of the technical skill and aesthetic sense that have always traditionally accompanied lamps and lights using these substances.

The Geniol petroleum lamps.
You’ll notice that the Geniol serves more than a decorative purpose when it flares up to an impressive 100 watts. Your friends will admire it – but it will also prove to be a useful, robust, durable object that will light up your garden or patio or other areas not provided with electric current – and which, of course, you can use in emergency if there is a power cut.

Operation.
We have to admit that it’s not so easy to get started. On the other hand, this is all part of its charm, to which we’re sure you’ll fall victim when you finally, and for the first time, get it to work. Read the instructions carefully! Here is a summary: fill it first with pure petroleum, screw the top on, and, using the pump provided, get the contents of the lower chamber up to the necessary pressure (shown by the manometer). This brings about carburation, which is the secret of the lamp’s incredible brightness. Ignition is effected by means of a pre-heating apparatus – you don’t have to use spirits! Occasional pressure checks are advisable. You are advised that the Geniol – like all other lamps of its type – gives off a distinct hiss in use.
