By the 2020s, work was being done to create safer glow sticks and alternatives. Canadian company LUX BIO, for example, developed glow stick alternatives such as the Light Wand which is biodegradable and glows with bioluminescence, rather than the chemiluminescence and LÜMI, which is a reusable and non-toxic alternative that glows with phosphorescence and is chemically and biologically inert.
