38.9Va.1 is an armature arrangement of 9 blown-glass spheres. 38V is a variant of the original 38 series where a large glass sphere is blown with a multitude of haphazard interior cavities, which intersect and collide in unpredictable ways. 38V is smaller and lighter. The interior cavities can be filled with plants or left empty.
The round, matte black canopy is 6.3" / 160 mm in diameter and 1.6" / 40 mm deep. For integral power supply.
