Tariffs are rising. An energy shortage is reality, not a scare story from the news. And here’s the situation: an LED screen has to shine brightly to be noticed on the street at all. And every hour of bright shining is money leaking out of the budget every day, no days off.

The temptation arises to solve this crudely: lower the brightness and forget about the effectiveness of running ads. That way you’ll only get a dim screen that no one sees in daylight, and the advertiser won’t achieve their goal during the ad campaign. The advertising turns into a gray rectangle. Its value — zero, and on top of that the advertiser won’t come back to you.

The question is framed differently. How to pay less without killing visibility and picture quality. There is an answer, and it’s not about “making it dimmer.” It’s about smart management.

Why LED screens eat up so much electricity

First, let’s figure out where the money goes.

LED screens for advertising are hundreds of thousands of diodes glowing at once. Consumption depends directly on brightness. The brighter the content, the higher the current, the higher the bill. This isn’t a linear trifle. The difference between running at full power and at half is dozens of percent of the bill.

Not all screens eat the same. Large LED screens on façades and LED billboards along highways consume the most — they have a large area and require high brightness for open space. An outdoor LED video display on the sunny side of the street needs more power than the same screen in the shade. LED advertising screens in an indoor environment — shopping malls, lobbies, covered stops — consume noticeably less, because they don’t have to “punch through” the sun. The first conclusion is already here: saving begins with understanding which medium of yours is the most voracious.

Now the key point that many people skip. A screen doesn’t need maximum brightness around the clock.

During the day, under direct sun, the screen really does have to “punch through” — otherwise the image burns out in the glare and can’t be seen. And at night? At three in the morning, that same brightness simply blinds passersby and burns electricity for nothing. The picture doesn’t get better because of it. It becomes excessive.

Add to this one more hidden factor — the equipment. Old energy-saving LED screens of the new generation consume less than diodes that are eight to ten years old. If part of the network is built on outdated modules, the bill is inflated before any settings at all. This isn’t a reason to replace everything at once, but it’s a factor worth keeping in the calculations.

Here’s where the money is hiding. Not in shining dim all the time. But in shining exactly as much as is needed for the specific hour of the day — and on hardware that doesn’t burn current pointlessly.

A brightness schedule: the simplest lever for saving

Let’s move from theory to practice. The most effective tool here is the LED display’s energy-saving modes, tied to time.

The logic is this. You don’t control brightness manually every time. You set up a schedule once, and the system itself changes the level throughout the day.

How this looks in a real case. The IAB Ukraine report “DOOH Casebook 2026” describes an approach applied in the Advision CMS dashboard. There, a flexible brightness schedule setup is implemented: the level automatically changes depending on the time of day. During the day, the screens run at 80–100% — for maximum visibility under the sun. In the evening and night period, brightness is lowered all the way to 30%. The result — electricity savings of up to 40–60% during the hours when high brightness simply isn’t needed (the full case is in the IAB Ukraine casebook).

Think about that figure. Up to 60% savings for part of the day — with no loss in daytime visibility at all. The advertising during the day is just as bright. At night — exactly as much as needed for it to be seen, but without blinding anyone.

Let’s do a back-of-the-envelope estimate of what this means in money. Imagine a network of ten outdoor screens. Each runs around the clock. Roughly a third of the day is evening and night, when maximum brightness isn’t needed. You lower it for this period by half or more — and it turns out that a significant part of the night-time consumption simply disappears from the bill. Multiply by ten screens. Multiply by twelve months. The sum that excess night-time brightness used to eat up every month turns into money that stays in the budget. And all of this without any new equipment — purely by configuring what’s already installed.

This is the answer to the question “how to pay less without losing quality.” Don’t cut brightness across the board. Cut it where and when it’s excessive.

Separately, it’s worth mentioning intelligent screen brightness control. A time-based schedule is the basic level. The next one is when the system accounts not only for the hour, but also for the season and the actual length of daylight. In summer the sun sets late, in winter — early. A fixed schedule of “lower at 18:00” switches on saving in time during winter, but too late in summer, because at six it’s still bright. Smarter logic ties the brightness reduction to the actual sunset, not to a rigid number in the settings. A trifle? Over a year across the whole network — again, noticeable money.

Why this matters specifically for out-of-home. Digital out-of-home advertising works in the harshest lighting conditions: from a blinding noon to complete darkness within a single day. This is exactly where the difference between “always shine at maximum” and “shine on a smart schedule” gives the biggest gap in the bill. An indoor screen in the stable light of a lobby doesn’t have this scope of saving — there are fewer fluctuations there too.

Software vs. hardware: why light sensors aren’t a cure-all

Here someone will say: why a schedule, there are hardware light sensors. Install a sensor — it adjusts brightness to the real light by itself. Sounds logical. In practice there’s a nuance.

Hardware sensors aren’t always installed. And if they are installed — they don’t always work stably. A sensor can get dirty, fail, give jumps in readings. On a network of dozens of outdoor LED screens, physically checking every sensor is a separate headache and a cost of maintaining LED screens.

A software solution works differently. It doesn’t depend on external factors and the state of the hardware. The schedule set in the system — it’s executed identically on all media, regardless of whether some sensor is clean or not. Predictably. Controllably. From a single dashboard for the whole network.

This doesn’t mean sensors are evil. It means relying on hardware alone is risky. A software schedule gives a basic, predictable saving that you can count on in the budget in advance.

A bonus people forget: LED screens live longer

Saving on the bill is the obvious benefit. There’s a second one, non-obvious.

Less brightness at night means less load on the diodes. And less load means a longer service life for the panel. LEDs degrade from heat and prolonged operation at maximum. By lowering the brightness where it isn’t needed, you don’t just pay less for electricity. You push back the moment when you’ll have to replace modules.

Count it yourself. Replacing part of the LED screens or repairing large LED screens is sums of a different order than a monthly electricity bill. By extending the panel’s lifespan even by a year or two, you save where the costs hurt the most.

In other words, smart planning of the screen’s operation hits two cost items at once: operational expenses on energy and capital expenses on hardware. One tool — two savings.

A different approach: saving through the creative itself

A brightness schedule is management from the side of the digital signage equipment. But there’s a second path, from the content side. And it also delivers numbers.

A bright, color-flooded picture forces the diodes to work at full. A dark palette — the opposite. The fewer bright pixels, the lower the consumption. This is physics, not marketing.

This idea was developed into a working technology. The LePub team from Publicis Groupe launched Dark Mode Ads — an approach that adapts creatives for digital out-of-home advertising to a darker palette. According to preliminary data, this can reduce LED screens energy consumption by up to 74% without losing campaign noticeability. The first campaign on the market to use the “dark mode of advertising” was, quite fittingly, the Italian energy company Plenitude. But LePub created the Dark Mode Ads digital platform, available to all brands, where they can experiment with the technology, including automatic conversion of their advertising materials to dark mode.

The conclusion from this is simple. Energy efficiency isn’t only about technology. It’s also about design. Modern  for advertising allows saving from two sides at once: a smart schedule plus a thought-out creative.

How to assemble this into a system

Now let’s put it all together. What an owner of a screen network can actually do to make the bill smaller.

First — a brightness schedule. A basic, mandatory step. Day — high brightness, evening and night — lowered. Set up once, works every day. This is the very lever that gives 40–60% savings during the night-time hours.

Second — centralized management. If you don’t have one screen but a network, manual control doesn’t scale. Here you’re saved by content management on LED displays from a single dashboard: one schedule is rolled out to all media, without going around each one physically.

Third — creative built for energy efficiency. Where it’s appropriate, a darker palette in the layout isn’t only style. It’s a smaller bill. Not every campaign allows this: a brand with a bright corporate color can’t be repainted. But where there’s freedom, a dark background instead of one flooded with light is a direct impact on consumption.

Fourth — accounting for service life. Keep in mind that lowered brightness extends the panel’s life. This is part of the economics, not a pleasant accidental bonus. Build this effect into the network’s payback calculation, rather than finding out about it after the fact.

And fifth — eco-friendly solutions for digital signage are no longer about fashion. Under conditions of energy shortage, responsible consumption is both reputation and a real resilience of the business to outages. The less you consume, the less you depend on tariff jumps and restrictions. And the less you load the grid during peak hours, when every saved kilowatt matters not only for your bill, but for the system as a whole.

Where to start in practice. You don’t need to redo everything in a week. The first step is to look at how much the network actually consumes at night, and switch on a basic brightness schedule at least on the largest media. This alone will give a first noticeable result on the next bill. Then — scale the approach across the whole network and bring in the creative component where the brand allows it. Saving here is cumulative: it works not once, but every night, for as long as the screens are switched on at all.

Summary

The question was this: can you pay less for electricity without killing the image quality on LED screens.

The answer is yes. But not through crudely turning down the brightness, which makes the advertising invisible. But through smart management: a schedule tied to the time of day, centralized control over the network, an ad creative adjusted for darker colors.

The numbers confirm this. Up to 40–60% savings on a brightness schedule. Up to 74% — on a dark creative palette. These aren’t theoretical promises, but approaches already proven on the market.

An LED screen isn’t obliged to be expensive in daily upkeep. It becomes that way only when it runs at maximum around the clock without need. Remove this excess — and the bill will shrink on its own, while no one will even notice the picture became more economical. Because during the day it will stay just as bright as it should be.
