This lens is a good replacement for a red Slo-Blo LED cover if you are using a light kit with an RBG (multicoloured) LED on your own custom made Ghostbusters wand. It is also perfect for the wand box flash LED. See the photos for examples of these.
The lens top has a 7mm diameter and the lower shaft (that goes in the hole) is 6.5mm. Inner diameter is 5.5mm.
(The replica Ghostbusters wand shown in the photos is not included.)
