Uw, my thats a big one! Very nice! Evidently there were huge industrial sized ones for lighting workshops. I've only seen pictures of those. If I can photograph and measure a real one I'd like to make one, one day.
RE rush lights I've not found them to be that smokey, possibly as I over do the rendering of the mutton fat, boiling it up in salt water at least twice. How thick are the rushes you're using as I'm getting quite a lot of light off of the thicker ones, the main down is how fast they burn down.
I'm having trouble finding images of how they were stored. In the reserve collection at St Fagans I found a tin candle holder which still had desicated, broken up rushes in it, much to mine and the curators surprise, I've also seen a photo of odd vertical wooden box with a fireplace like hole at one end. I assume you stood the lights on their ends and pulled them out as required. There's mention of them being tied up in bundles but that would leave them open to mice and insect attack.
