LEDs use low-voltage of 12 volts with acrylic being the primary component which makes them robust, safe to handle and easy to courier.
A neon glass light has an input voltage of 3KV to 18KV, which used to be the industry standard because of their long lifespan. That changed once LED lights came into play with the LED neon having an input voltage of 12V, which makes them safer to use.
A 12V DC LED system is a common voltage platform. Many electrical systems operate on 12V DC. Many batteries for vehicles including boats and RVs operate on 12V DC.
12V LED systems have a lower electric shock risk. Because 12V is a much lower voltage compared to line voltage (120/240V), it is more difficult for the electrical current to overcome the built-in resistance of human skin and other objects.
12V LED systems are more reliable, and can be repaired and serviced. In 12V LED systems, the transformer and power supply are located away from the LEDs, typically in a cool and vented area. This improves the reliability of the electronics, and most significantly, allows for the faulty electronics to be repaired or replaced with ease.
Regards to robustness, traditional neon gas signage is made from glass which is moulded with heat from fire and bent into shape. This can result in a very fragile sign. HiNeon rigid LED neon is mainly crafted out of solid acrylic which makes it very unbreakable. It’s easier to ship around as well.
