Firefly Lacrosse is offering an ultra compact, super bright, black light flashlight to "charge up" Firefly Lacrosse balls while you're on the go! The science: black lights use UV light to react with phosphorus in the balls causing the balls to glow. The wavelength of the UV light is perfectly suited to get the balls to glow brighter and longer!
