The lamp shade is made of fir and cherry wood rings stuck together. The thinly cut cherry wood lets light through creating a natural reddish glow and the hand carvings on the lamp shade sprinkle small pecks of light here and there. The perfect ambient lighting for romantic evenings :) We used hemp rope to cover the cable and the visible parts of the bulb holder and linen seed oil and natural wax to treat the wooden material. We use bulb holders E14, regular light bulbs up to 15W or halogen ones up to 28W, and electric plugs 220V. The length of the cable is 1.5m.
