Which is bigger, a 16.3 inch or a 17 inch lava lamp?
The 17 inch lamp is taller, but the 16.3 inch lamp is bigger where it counts: its globe holds 52 oz against 32 oz. The 16.3 inch is the wide one, 5.9 inches across against 4.5.
How much space does a 14.5 inch lava lamp need?
A circle 3.9 inches across and 14.5 inches of height: the lamp weighs 3.2 lb and stands on a base about the size of a coffee mug. Leave a hand of clear space around it, since the globe runs hot.
