How do you compare the cost of high-temperature LEDs with traditional lamps?

The cost of high-temperature LEDs compared to traditional lamps is significantly lower in the long term, even though the purchase price is higher. The difference lies in energy consumption, replacement frequency, and maintenance costs that quickly mount up in extreme environments with traditional lamps. In this article, we will break down the most frequently asked questions about this comparison step by step.

Which cost items count towards an honest comparison?

An honest comparison between high-temperature LEDs and traditional lamps goes beyond the purchase price. The actual costs consist of several components: the initial investment, energy consumption, replacement costs, labor costs for maintenance, downtime costs, and any costs for cooling or protective enclosures.

In regular environments, these additional cost items are already relevant. In industrial environments with extreme heat, dust or vibrations, they become even more significant. A traditional lamp that normally lasts two years can already become defective within a few months in a steel factory or foundry. The replacement costs are not only the lamp itself, but also the labor and the production stoppage that go along with it.

Costs that must be taken into account in a complete comparison:

Purchase price of the luminaire or lamp
Energy consumption per year (kWh)
Number of replacements over the lifetime
Labour costs for replacement and maintenance
Costs for accessibility (forklift, crane standstill)
Any production or operational downtime
Cooling requirements or additional protective measures

Only when all these costs are taken into account does a comparison give a realistic picture of what lighting actually costs.

What is TCO and how do you calculate it for industrial lighting?

TCO stands for Total Cost of Ownership, or the total cost of ownership over the entire life cycle of a lighting installation. For industrial lighting, you calculate TCO by adding the purchase costs to all recurring costs such as energy, maintenance, and replacement over a defined period, usually ten to fifteen years.

A practical calculation works as follows:

Determine the purchase costs of the fixture, including installation.
Calculate the annual energy consumption based on power and operating hours.
Estimate the number of replacements over the chosen period and calculate the associated labor costs.
Add any costs for downtime, cooling or additional protection.
Compare the total amount with the alternative over the same period.

By high temperature lighting The TCO calculation is particularly relevant because the conditions significantly shorten the lifespan of traditional lamps. A fixture that is twice as expensive but lasts ten times longer without replacement has a much lower TCO in practice.

How much energy does high-temperature LED consume compared to traditional lamps?

High-temperature LEDs typically consume fifty to eighty percent less energy than comparable traditional lamps such as halogen lamps, high-pressure sodium lamps, or metal halide lamps at equivalent light output. This difference is significant and has a direct impact on annual energy costs, especially in installations that are continuously or for long shifts.

In industrial environments, lighting systems often run for twelve to twenty-four hours per day, seven days a week. With an installation of tens of luminaires, energy consumption quickly mounts. LED provides the same or better light output with a fraction of the power, which significantly increases the energy savings on an annual basis.

In addition, traditional lamps produce a lot of heat as a byproduct. In environments that are already very hot, this can cause additional cooling needs. LED produces less heat at the light exit end, which in some applications also reduces cooling costs.

How often do traditional lamps need to be replaced in extreme conditions?

In extreme conditions, traditional lamps must be replaced significantly more frequently than the factory specifications indicate. High temperatures, vibrations, dust and moisture accelerate the wear of filament lamps, ballasts and contact points. What lasts two to three years in an office environment can collapse after just a few months in a steel factory or on a crane.

High-pressure sodium lamps and metal halide lamps are susceptible to thermal stress. At temperatures above sixty or seventy degrees Celsius, the lifespan decreases sharply. In environments with infrared radiation, such as around high-temperature furnaces or smelters, this effect is even more pronounced.

The consequences are not just financial. Any replacement requires downtime, accessibility, and labor. In dangerous or hard-to-reach locations, such as on a crane beam or above a production line, those costs are high and the safety risks are real.

When does high-temperature LED pay for itself?

In most industrial applications, high-temperature LEDs pay for themselves within two to four years, depending on energy prices, the number of burn hours, and the replacement costs of the traditional installation. In extreme environments, where replacement is frequent and costly, that payback time may be shorter.

The payback period is determined by the difference in annual costs between the two options. The higher the energy bill and the more often the traditional lamp is replaced, the faster LED will recoup that higher purchase price. In environments with 24/7 operations and high labor costs for maintenance, this effect is most pronounced.

It is also worth looking into tax-related possibilities. In the Netherlands, there are schemes such as the Energy investment allowance which can reduce the net investment in energy-efficient lighting and shorten the payback period.

Which factors make the comparison different for extreme environments?

In extreme environments, the ratios change fundamentally. Standard comparisons between LED and traditional lighting are based on normal operating conditions. Once temperatures rise above one hundred degrees, vibrations are constant or corrosive substances are present, the assumptions on which those comparisons are based become invalid.

Factors that make the equation specific for extreme environments differently:

Accelerated wear of traditional lamps due to thermal stress
Higher labor commitment for replacement in dangerous or hard-to-reach locations
Required protection classes and enclosures that increase the purchase costs of traditional systems
Risk of unexpected downtime and associated production stoppage
Specific requirements regarding temperature resistance that limit the range of suitable traditional lamps

In such environments, a standard LED fixture is not a solution either. Specifically designed high-temperature fixtures are needed to function reliably. The comparison therefore does not only concern LED versus traditional fixtures, but also which type of LED is suitable for the conditions.

Practical example: VPK Paper

VPK Paper wanted to convert the lighting in the paper mills in Belgium to LED. In and around the paper machine, the temperature can in extreme cases reach +120 °C, with steam development and very high humidity. After several trials with different suppliers, one trial with Snapper HT wel succeeded. They then took JEL Products care of the light design, the engineering and the design of the installation and supplied 98 Snapper HT luminaires in AC version. The installation provides 100 to 200 lux in the machine, at 35 W per luminaire.

Each failed trial cost time, money, and trust in the conversion to LED. In a cost comparison, such costs often disappear from view, because only the purchase price and energy consumption are taken into account. A cheaper fixture that fails after a short time puts replacement, installation time, and disruption to production costs again into the equation. The comparison with traditional lamps or standard LEDs is only fair when the lifespan is taken into account under real-world conditions, and a trial under those conditions provides certainty about this before the full investment is made.
