Providing you with a reliable light source that glows all night long and recharges quickly by absorbing light, these advanced glow lights will last forever. The glow-in-the-dark strontium aluminate crystals will not degrade over time nor wear out after a certain number of uses. They will keep recharging forever! The crystals recharge by absorbing any light - sunlight, ambient room light or even a flashlight. They will fully charge in 1 - 10 minutes of light exposure and glow for more than 10 hours. The Scout Pack includes a small UV Paqlite, UVO Necklace, UV GloStik and 6” Tooblite.
