Frequently Asked Questions About LED Birthday Neon Signs
Is there a warranty with your party neon signs?
If you purchase your happy birthday neon sign from Radikal Neon®, you automatically get a 2-year warranty that covers both electrical and construction components, such as AC plugs, dimmers, or transformers. Your warranty is valid from the day we ship it!
Learn moreHow long will my happy birthday neon signs last?
One of the benefits of our LED neon signs is their durability. Radikal Neon®, we build our signs to last up to 40,000 hours or almost 5 years! If overtime you notice the lights start to fade and switch off, it may be time to consider repairing your sign or purchasing a new one. However, if you hope to keep your sign running as long as possible, consider adding our wireless dimmer remote to your purchase at checkout. This way you can have a happy birthday with a neon sign that sets the mood for your event.
Learn moreWhat is the difference between traditional and LED party neon signs?
Traditional neon lights are almost taboo these days. Since they are more dangerous than practical for daily use, we use LED neon with Rad Super Mini LED neon instead. Since these lights are less hot and more efficient and durable, they are the superior option when it comes to neon party signs.
Learn moreCan my happy birthday neon sign be repaired?
Of course! No matter what issue your neon sign is having, Radikal Neon® is here to help. If electrical or constructive components break down, your repairs could fall under your 12 month warranty. If there are other issues, we can still repair or replace your LED neon lights easily. However, if you were to go with a traditional sign, repairs could be far more expensive.
Learn moreAre happy birthday neon signs dangerous?
Traditional neon uses glass tubing which can be dangerous if they drop and shatter into a million pieces. However, our LED neon party signs are made with acrylic tubing which stays cool to the touch and uses a low 12V power draw. This means they are completely safe for guests of all ages.
Learn moreHow do I install my happy birthday neon signs?
And you do not need to worry about how you were going to install your neon birthday party decor when you go with Radikal Neon® LED signs. The installation process can vary depending on whether you chose many screws, suspension wires, or standoff screws. Grab your power tools and a friend and get ready to set up for your birthday party event.
Learn moreHow long will it take to make my neon sign?
There are several shipping options available when you make your purchase. Since Radikal Neon® is one of the fastest LED neon sign manufacturers in the world, we provide two separate options. You can go with a Non-Urgent order and get your neon party sign within four weeks or you can select Expedited Lead Time when you check out and expect your sign to arrive in 14 days or less.
Learn moreAre happy birthday neon signs LED?
Many neon signs use traditional designs, including glass tubing full of electrified gasses like argon and neon. However, Radikal Neon® uses LED lights which are safer and more affordable.
Learn moreCan I use my party neon sign outside?
If you are hoping to host an event outdoors, we can build an acrylic box around your sign which is waterproof and weatherproof. We use silicone glue applied to either end of the strip to ensure it is completely sealed. This way, you can keep your party sign outside without worrying about weather damage.
Learn moreWill my party neon sign get hot?
No! You do not have to worry about your sign getting too hot or posing a fire risk. Our LED neon lights only ever get warm, even if they have been on for several months in a row. However, if you purchased traditional neon lights, the glass tubing is sure to get hot in a matter of hours.
