Bommel Trio Hanging Lamps - Bowl, Dome + BulbNew at Venn + Maker! Bommel Bottle Trio Bowl, Bottle, Bulb The Bommel Collection was inspired by my first series of stump lamps by experimenting with found wood and turning them on a wood and metal lathe. Since then, these pieces are now wood turned from kiln dried solid birch by local Montreal woodturner Pierre Tardif. Materials: Birch, black porcelain socket, cloth covered cord (either with thumb switch or ceiling canopy), LED soft white bulbs.
