Traditional glass neon signs are made from glass tubes filled with gas that emits light when electrified. They offer a vintage aesthetic and a warm, distinct glow. However, they are fragile, consume more energy, and can be costly to repair.LED neon signs, on the other hand, use flexible silicone or PVC tubes filled with small LED lights. They are more energy-efficient, durable, and safer due to their lower heat emission. LED neon also allows for more flexibility in design due to its ability to bend into various shapes and offer a wide color range.
