So this is Reaper's large fire elemental that I got in the first Bones Kickstarter.
Turns out the bottom part is hollow. Hollow enough for the LED from a tea light, anyway.
This is a D&D Miniatures fire elemental, probably listed as some synonym for "really big fire elemental". Unbasing this guy was a pain - there are several pegs involved. Easiest way is to drill several holes in the bottom and break the base in half. He isn't as nice a technical sculpt as the Reaper model. but the light can go a lot further up and the orange is more convincing than the Reaper red.
With The Lady in Red for scale. They're not little in comparison, but the table footprint is the same as it would be without me hiding lighting infrastructure in a juice lid. These are from the Simply brand. Their Apple juice is really tasty if you like that sort of thing.
