Glow Gravel Green Bulk 2 6mm 1kg
Glow in the Dark Gravel offers self illuminating, electricity free lighting that will recharge itself over and over again and last indefinitely. The glow gravel is an actual source of ambient light, it absorbs radiant U.V. energy from the sun (or artificial light) and converts it into longer wavelengths of the visible spectrum, thereby producing a visible light. By day the gravel is a very pale green. The gravel represents a cutting edge technology in zero energy self sustaining light, and can be used in a multitude of applications, you can mix it in with your regular gravel to create a 'star path'. It can be set in a clear resin to create glowing floors, ornaments, funky kitchen worktops, the potential applications are endless. The gravel is also water resistant making it suitable for aquatic and other submerged applications (we would always recommend that it is washed first).
Not just for outdoor use, the glow in the dark gravel can also be incorporated into table decorations, as it can be easily charged by exposing it to light (UV blacklight is even better). The shards of gravel range between 2mm-6mm and can be purchased in 1kg bags, there are discounts for larger quantities suitable for larger projects and applications.
The 'glow' time and brightness depends on various factors such as how much light it will get in the daytime, and how dark an area it is placed (the gravel look better the darker the surrounding area). Even down to how different people see 'glow' in the dark so there's no concrete answer, but 'afterglow' is around 10 hours. Please read our guide on getting started with Glow Gravel.
