A Lux JL whereby the designation L indicates it was to be pressurised with Luft (Air) instead of CO2. Given the scarcity of Lux catalogues, it is tricky to date this exact model. I'd estimate her date to lie between 1904-1908. The JL is listed in a 1904 catalogue and it is shown in the catalogues published the years after. By the time the 1908 catalogue was published, the hood had two vents, such as this example already featured in the gallery HERE. This lamp is heavy! It weighs in at around 16 kg's/35 pounds. The lamp was surprisingly complete. I am thankful the glass was in one piece, albeit it has some scratches. Unlike the Lux J, which operates on a hollow-wire fuel system, the JL has a large bell right below the burner, whereby by means of an air-pump one can pressure the lamp. Lux actually had this down as a portable worklight/lamp! Surely I wouldn't want to be moving around the lamp very often! And finally, here it is next to a Tilley FL6.
