https://stream.echo6.co/videos/watch/8e6436a3-074d-4e91-b016-e42999f1b8ec I've been playing around with a very finely balanced glitter lamp running from the small amount of heat from GU10 LED lamps, and this particular lamp is very appealing because it is designed for hydroponic use (growing plants) and has two red and one blue 1W LEDs in it. The result is a mass of red and blue sparkles in the lamp vial and all the walls in the room being covered by swirling dots of colour. The lamp I'm using is filled with a saturated calcium chloride solution finely balanced to support glitter at neutral suspension. It appears that some commercial lamps use calcium chloride, but others use a different density modifier like sodium nitrate. I'm not sure. Ideally I'd send a sample to a lab for chemical analysis, but that's quite an expensive thing to do to for mere curiosity.
