Hey there, I’m Jake, and for the past seven years, I’ve run a small neon light decor supply company—we’ve outfitted cafes, retail stores, home offices, and even a few music festivals with custom neon signs. Early on, I’ll admit, we didn’t think much about energy use. Neon was always billed as “efficient” compared to old incandescent bulbs, right? But a few years back, a regular client— a family-owned bookstore in Portland—sent us a note saying their electric bill had spiked 18% after installing our large storefront neon sign. That shook me. I dug into the numbers, tested every neon variant we stocked, and worked with an electrical engineer buddy to figure out where we were dropping the ball. Today, I’m sharing what I learned, from how we tweak our supply to what our customers can do, to make neon light decor way more energy-saving—without losing that bright, warm glow everyone loves. Neon Light Decor
Let’s start with the basics: not all neon signs are created equal, and the oldest tech we used to carry (traditional glass tube neon) is actually the most energy-heavy. Traditional neon signs work by passing a high-voltage current through a glass tube filled with neon gas (or sometimes argon with a phosphor coating for different colors). That high voltage means the transformer (the part that powers the sign) draws a lot more power than newer options. We used to source these transformers from overseas without checking efficiency ratings—we just cared about cost. But after that bookstore incident, we switched to only UL-listed Energy Star transformers for all our traditional neon stock. These transformers are 30-40% more efficient than standard ones because they use soft-switching technology, which reduces energy waste from electrical resistance during on-off cycles.
Wait, but even with Energy Star transformers, traditional glass neon still has a hidden drain. A full-color neon sign for a cafe might have 12 tubes, each 1.5 feet long. Each tube needs a separate transformer? No, that’s not right—wait, no, some multi-tube signs use a single transformer with multiple output taps, but we used to oversize transformers to “play it safe.” That’s a mistake. If a sign needs a 12kV transformer, we shouldn’t use a 15kV model; the extra voltage just bleeds off as heat, which is both energy waste and a fire risk. Now, we calculate transformer size precisely for every custom order: we measure the total length of the neon tubes, the gas type, and the desired brightness, then pick the smallest transformer that meets those specs. Last year, we swapped out 27 oversize transformers from past orders for correctly sized ones, and our customers saw an average of 22% lower energy use on their signs. It’s a small change, but it adds up for someone running a 24/7 retail store.
Now, the biggest game-changer we found was ditching traditional glass neon for LED neon flex. I know, I know—some purists say LED neon doesn’t have that “authentic” neon feel, but modern LED flex technology is almost indistinguishable from glass neon, and it’s 75% more energy-efficient. Let’s break that down: a 10-foot glass neon sign uses about 100 watts of power, while a 10-foot LED neon flex sign uses just 25 watts. That’s a huge difference, and our engineers confirmed it’s not a gimmick—LEDs convert almost all their energy to light, while glass neon wastes about 60% as heat. For our commercial clients, which run signs 12 hours a day or more, switching to LED neon flex cuts their annual neon energy use by $150-$300 per sign. The only catch we had to troubleshoot was color accuracy. Early LED neon flex had washed-out reds and blues that looked fake. Now, we source flex strips with a CRI (Color Rendering Index) of 90 or higher, and we work with our manufacturers to adjust the phosphor coatings to match the exact hue of traditional neon. Our customers can’t tell the difference in a blind test, and their energy bills are way lower.
But even if you’re using LED neon, there are small choices that make a big difference. For example, color. Red neon (whether glass or LED) uses less energy than blue or purple, because red light has a longer wavelength, so the LEDs or gas molecules need less energy to produce it. Wait, let’s make that precise: a red LED neon strip uses about 18 watts per 10 feet, while a blue one uses 28 watts. That’s why a lot of our clients go for neutral colors for storefronts—they get the exact same brand vibe but save energy. We also add a dimmable option to all our LED neon signs, which we didn’t do until two years ago. Dimming a sign by 50% cuts energy use by about 50%, and most of our customers don’t run their signs at full brightness all the time. For example, a home office sign might be dimmed at night when it’s not the main light source, saving $20 a year on power. We also recommend motion sensors for signs in spaces that aren’t always occupied—like a store’s back patio sign, which only needs to be bright when someone is walking by. We don’t sell motion sensors directly, but we partner with a small smart home company to recommend them to our clients, and the feedback has been great. For a 20-foot patio sign, a motion sensor cuts energy use by 80% when the business is closed.
Another area we overlooked for a long time is installation. If a neon sign is mounted incorrectly, it can waste a lot of energy. For example, if a sign is installed near a window in direct sunlight, the transformer has to work harder to keep the sign cool, because heat can damage the gas in glass neon or the LED chips. That extra work adds up to 10-15% more energy use. Now, we include free installation consultations with all our custom commercial orders, and we train our installers to mount signs at least 12 inches away from heat sources (like HVAC vents, sunlight through south-facing windows, or even other electronics). We also recommend using reflective backplates instead of matte ones for indoor signs. A matte backplate absorbs light, so the sign needs to be brighter to be visible, which uses more energy. A reflective backplate bounces 90% of the light forward, so you can run the sign at a lower brightness and still have it look vivid. We started including reflective backplates as a standard option in 2022, and our customers report that their sign’s brightness stays the same, but their energy use is down 10%.
Wait, what about maintenance? A lot of people don’t think about that, but a dirty neon sign can use more energy. Dust on glass tubes or LED flex strips blocks light, so again, the sign needs to run brighter to be seen. We now include a free neon cleaning kit with every sign we sell, with microfiber cloths and a mild, non-abrasive cleaner (no ammonia, because that can damage the coating on LED flex). We also send a quarterly email to our customers with maintenance tips, like how to check for loose connections (loose wires can cause electrical resistance, which wastes energy) and how to adjust the transformer if the sign starts to dim. Last year, a restaurant client told us that after cleaning their neon sign, their electric bill for the sign dropped by 12%—that’s a simple, free fix that almost no one knows about.
I know some of you might be thinking, “Wait, I bought a neon sign from a big box store, not your custom company—what can I do to make it more energy-saving?” Don’t worry, a lot of our tips apply to any neon sign, no matter where you bought it. First, check the transformer’s efficiency rating. If it’s a standard, non-Energy Star transformer, consider replacing it with an Energy Star model. You can find these at any hardware store, and they’re not expensive—usually $20-$30. Second, if you have a traditional glass neon sign, see if you can convert it to LED flex. A lot of companies (including us) offer conversion kits that let you swap out the glass tube without changing the mounting, so you don’t have to re-drill holes or redo your sign’s design. That’s a cost-effective option, usually half the price of a new custom sign. Third, install a timer. Even a cheap $5 timer will let you turn the sign off when you’re not using it—no more leaving it on all night while you sleep. For a sign that runs 10 hours a day, a timer cuts energy use by 30% right there.
Now, let’s talk about the science behind why this all works, because I don’t want to just give you tips without explaining why. Neon lights work on electrical current, so energy use is measured in watts, right? The formula for neon sign energy use is roughly: Watts = (Voltage x Current) / Power Factor. Traditional glass neon has a low power factor—about 0.5 to 0.6, which means only 50-60% of the electricity drawn actually goes to light; the rest is lost as heat. LED neon has a power factor of 0.9 or higher, which means almost all the electricity goes to light. That’s why LED is so much more efficient. We worked with our engineer buddy to measure this for all the signs we stock, and we now list the power factor and wattage for every sign on our website, so our customers can make informed choices. No more hiding behind “neon is efficient”—we’re transparent about the numbers.
I should also mention that making neon decor more energy-saving isn’t just good for your electric bill—it’s good for the planet. A single 10-foot traditional neon sign uses about 100 kWh of electricity a year, which is the same as running a refrigerator for a month. If every small business that uses neon switched to LED flex, we’d save over 2 billion kWh a year in the U.S. alone, according to a 2023 study from the Department of Energy’s Commercial Building Energy Efficiency program. That’s enough power to light 180,000 homes. It’s not a huge number, but it’s a start, and it’s something we can all do, whether you’re a neon supplier, a retail owner, or someone who just bought a neon sign for their home.
I won’t lie—making these changes wasn’t easy. We had to switch suppliers, adjust our manufacturing process, offer more support to customers, and take the time to educate people about energy efficiency in neon. But the feedback we’ve gotten has been amazing. The Portland bookstore that had the spiked bill? After we swapped their oversize transformer for a correctly sized Energy Star one, their bill went back down, and they re-ordered another sign last year. A coffee shop in Seattle switched to LED neon, and they told us they saved enough on electric bills to hire a part-time barista. That’s the part that matters to me—not just selling signs, but helping people save money and do something good for the environment.
If you’re a small business owner, a homeowner, or another neon supplier looking to make your signs more energy-saving, let’s talk. We’re always experimenting with new materials and methods, and we love working with customers to find solutions that fit their needs.
