Anyone replacing old industrial hall lighting with LED wants to know one main thing: how quickly will the investment pay for itself? In many warehouses, production plants, and workshops, the payback period is within a few years if the existing system causes high electricity costs and is in use for many hours a year. However, wattage and purchase price are not the only decisive factors. Operating hours, maintenance effort, mounting height, lighting level, and any control systems also have a major impact on profitability. You can read more background information and our approach in Hallenbeleuchtung auf LED umrüsten.
For an informed decision, you should therefore not only compare energy consumption (see Verbrauch und Energieeffizienz von LED-Beleuchtung), but also weigh the total annual operating costs of your old system against the planned LED solution. This is precisely what shows whether the new industrial lighting is not only more efficient, but also pays for itself quickly in economic terms.
What industrial hall profitability truly depends on
LED high bay lighting pays for itself particularly fast when existing fixtures are inefficient and operate for long hours. Typical scenarios include older HQI, HQL, or fluorescent systems in facilities with shift work, extended operating hours, or continuously illuminated zones. That is usually where the biggest impact on electricity costs can be made. For typical storage environments, you can find suitable options at LED industrial lighting.
Then there is the maintenance factor. In a high-ceilinged hall, replacing a light source is significantly more expensive than in smaller spaces. Scissor lifts, cordoned-off areas, labor deployment, and potential operational disruptions often cost more than the replacement part itself. Modern LED high bay fixtures noticeably reduce this effort in many projects.Ook dimmen, aanwezigheidsmelders of daglichtregeling kunnen de terugverdientijd verder verkorten, als niet elke zone altijd op vol vermogen hoeft te worden verlicht.
De terugverdientijd wordt vooral langer wanneer de hal maar zelden wordt gebruikt of wanneer de nieuwe installatie te ruim is gedimensioneerd. Juist daarom moet de keuze van de armaturen altijd passen bij het gebruik en de geometrie van de hal. Een goede eerste afweging is High bay lights or continuous row lighting?
How to calculate the payback period
For practical purposes, a simple basic formula is usually sufficient:
Payback period = net investment/total annual savings
The net investment includes purchase, accessories, installation, and any dismantling of the old system, minus potential subsidies. The total annual savings consist of lower electricity costs and lower maintenance costs.You are therefore comparing the total annual costs of the old and the new system.
You must record these input values
- Number of existing and planned luminaires
- Actual system power per luminaire
- Operating hours per day and per year
- Current electricity price in euros per kWh
- Investment costs for luminaires, accessories, and installation
- Maintenance costs of the old installation, including labor time and lifting equipment
- Potential savings through sensors, dimming, or zone switching
The more accurate this data is, the more realistic the result. Especially in hall lighting, operating hours are often underestimated. Lead times, safety lighting, reserve zones, or shift changes often cause the installation to run longer than expected.
Example of a realistic calculation for a hall
| Metric | Old system | LED system |
|---|---|---|
| Number of fixtures | 24 | 24 |
| Power per fixture | 400 W | 150 W |
| Operating hours per year | 4,000 | 4,000 |
| Annual consumption | 38,400 kWh | 14,400 kWh |
| Electricity costs at €0.30/kWh | €11,520 | €4,320 |
In electricity costs alone, the LED solution in this example saves €7,200 per year. If in addition 1.800 euros in annual maintenance costs of the old installation disappear, the total savings amount to 9,000 euros per year. With a net investment of 18,000 euros, the payback period is approximately 2 years. The example clearly demonstrates why LED warehouse lighting is particularly profitable where energy consumption and maintenance have been high until now.
Why just electricity costs are not enough
A pure comparison based on wattage falls short for warehouse lighting. For true profitability, the entire lifecycle matters. When old high-wattage fixtures frequently experience light source failures, this not only leads to material costs, but often also to labor costs, access equipment, and operational disruptions within the company. In warehouse and production environments, this can be a significant cost factor.
Realistically factoring maintenance and downtime into costs
The higher the hall and the more difficult the access, the more service visits impact costs. If routes need to be blocked off, machines protected, or processes interrupted, every intervention takes longer. Therefore, the cheapest fixture to purchase is not automatically the most cost-effective solution. The quality of the driver, thermal management, and lumen maintenance play a crucial role in the actual payback period.
Lighting design improves the payback period
Equally important is an appropriate lighting design. Simply replacing existing wattages carries the risk of insufficient light, an unnecessary number of fixtures, or uneven light distribution. For profitability, what matters is not the lowest wattage per fixture, but whether the illuminance, uniformity, and light distribution suit the layout of the hall.Hall height, shelving aisles, activities, and reflection values also help determine how many fixtures are actually needed. Careful planning prevents oversizing and directly improves the payback period.
How much light a hall really needs
The demand for the number of lumens cannot be answered generally. The decisive factor is the desired illuminance in lux on the working surface. Simple traffic or storage zones usually require less light than assembly, inspection, or finer work in the workshop. In addition, hall height, optics, beam angle, and uniformity influence how much of the generated luminous flux actually ends up where it is needed.
For commercially used halls, the dimensioning is often tailored to the application and to standards such as DIN EN 12464-1. In practice, this means: first determine the surface area, task, and mounting height, then choose the appropriate LED high bay fixtures.Anyone who looks only at a high lumen output will soon buy the wrong product for their application and, in the worst case, even worsen profitability.
Payback period is not the same as depreciation
In practice, payback period and depreciation are often confused, but they refer to different things. Here, payback period refers to the economic timeframe until the investment is recovered through lower running costs. Fiscal depreciation, on the other hand, follows its own rules. The applicable depreciation period for a lighting installation depends on the specific classification and the rules in effect in the year of purchase. For a binding tax assessment, it is advisable to check the current regulations with your accounting department or a tax advisor.
FAQ on the profitability of LED high bay lighting
What does 1 hour of LED lighting cost?
You can calculate this by multiplying the power in kW by the electricity price. A 150W LED fixture consumes 0.15 kWh per hour. At 0.30 euros per kWh, one operating hour costs 0.045 euros. For 20 such fixtures, that is 0.90 euros per hour.
How much does an LED fixture consume per hour?
The consumption per hour corresponds directly to the power. A 100W LED high bay light consumes 0.1 kWh per hour, and a 200W fixture consumes 0.2 kWh. To calculate the annual costs, multiply this value by the actual number of operating hours per year.
When is a payback period considered good?
This depends on usage, the amount of the investment, and maintenance savings. In facilities with long operating hours, a retrofit can become profitable within just a few years.
More important than a rigid target value is that the new installation is properly designed in terms of both lighting technology and economics.What is the depreciation period for LED lighting?
The tax depreciation period is not automatically the same as the economic payback period. Decisive factors are the tax regulations applicable in the relevant year and the specific classification of the installation. For a substantiated answer, the current depreciation scheme must be checked.
How many lumens does hall lighting need?
Not only the number of lumens is decisive, but also the desired lux level on the usable surface. As a rough guideline, simple storage and traffic areas are often lower than assembly or inspection zones, which clearly require more light. Surface area, hall height, optics, and the work task determine the actual requirement. A lighting calculation is therefore more useful than a general lumen value.
Does a payback period calculator replace lighting planning?
No. A calculator shows the economic side, but not whether the illuminance, uniformity, glare, and fixture layout are suitable. For a well-founded project, profitability and lighting planning must always be reviewed together.
