Filthy Edna


Filty Edna 1 was a prototype lamp manufacture in 2014 / 2015, to trial a number of innovative concepts, including the use of individual 18650 cells. We manufactured a very low volume (a 1 off batch of less than 30 lamps). The Filthy Edna 2  (production version of the Edna 1) was subsequently launched at Hidden Earth 2019.
