Voltage does not rely on UV, neon or black lights to create glow. Instead, its self-illuminating. Tiny, microscopic particles in the gel come together in the mixing process to produce a bright colorful glow that can be seen in partial light and in the dark for at least 6-8 hours. The glow is bright enough to even use in lieu of a flashlight to go through a campground at night!
