Straight science, no hand-waving. The Science & FAQ library answers the questions buyers actually ask before clicking add-to-cart: heat, safety, lifespan, power draw, and the gases inside the glass. See what gas is used in neon signs (and how each gas makes a color), how long neon signs last with LED vs. glass lifespan data, and whether neon signs use a lot of electricity—with real watt math. We also cover fire-hazard facts for glass versus LED and how hot the tubes really get, so you can hang your sign with facts, not folklore.
