Max Graetz invented a process to make gas of petroleum. This petroleum gas has a high calorific value and energy content, this creates a hot blue flame. Particularly beautiful pressure lamp in chrome with orange/red shade. Lamp is ideal for on the boat, beach or camping. The corresponding (new) sock is included. Physical characteristics: Size: Height approx. 41 cm (including handle approx. 58 cm) Diameter bottom approx. 17 cm Weight approx. 2750 grams. This pressure lamp will be packaged with care, and shipped with Track & Trace code.
