We expanded our business with a new innovation as we introduced our very first headlamp.
Although headlamps had existed since the early 1900s (mainly used by miners who had them attached to their soft caps) they weren’t that powerful. After 12 hours, the lamps would produce less than 5 lumens. They also had to be checked on a daily basis for maintenance.
We named our first headlamp Zeiler and the retail price was €0,8.
