CORE Glow FAQs

What kind of light works best to charge the glow pebbles? Sunlight! But, if that is at a minimum, then various artificial lights work just great as well, i.e. black light, fluorescent and incandescent lighting
How long should I charge the pebbles? For a full nighttime glow, a minimum of 10 minutes is needed to give a full charge (light source dependent). Allowing the pebbles to glow between 10-12 hours long (in the dark of course!)
Is the glow from the pebbles the same as from solar powered garden lights? No. CORE glow lighting is considered ambient light. They will light your way in dark conditions but don’t compete with regular lighted conditions (your eye compensates for the ‘brighter’ object). That said, CORE glow doesn’t ruin your night vision. It also lasts a lot longer than most solar garden lights: 20 years!
 What makes them glow? A chemical element called Strontium Aluminate. An activator, Europium, is added to make the Strontium Aluminate a photophosphorescence (glow).
 Is it safe? It is both biologically and chemically inert, so safe for home use.
Other Interesting bits of Info Previous ‘glow in the dark’ products where made with zinc suphide, which are only useful for 35-45 minutes. Strontium aluminate afterglow can be visible for several days or more! You can even read by the initial glow of our products (for the 1st minute or so anyway).
What is the best way to view CORE glow? If your CORE glow stones have a new charge, then you can easily see them when going from a lit room into a dark room. BUT, the afterglow is best seen with eyes that are fully dark-adapted. Check out the CORE glow at 3 a.m.!
