The warranty period varies per product line because the construction differs. Choose your luminaire below and you will immediately see which period applies, what it applies to, and where the terms and conditions can be found.
For us, a warranty is not an after-the-fact sales pitch, but the result of how a fixture is built: cast housings, sealed 316 bolts, vapor-phase reflow soldering, a coating that withstands 1,000 hours of salt spray, and every fixture individually tested with a thermal imaging camera and recorded by serial number. What is covered under this and what is not can be found on this page and in the terms and conditions.

5year warranty
Five years on the complete luminaire, under heavy industrial use and within the specified parameters.
| Housing | 5 years |
| Other parts | 5 years |
| Conditions | Floodlights and work lights |
These luminaires operate in the harshest conditions of the range: cranes, mobile machinery, offshore, and high temperatures. The warranty period applies to the entire luminaire, including the driver and seals, because those components are the critical wear parts in these environments. No periodic maintenance is required, and there are no consumable parts.
| Housing, coating and bracket |
| LED modules and lumen maintenance |
| Internal electronics driver |
| Seals and cable entries |
| Front, polycarbonate glass |
| Application outside the specified temperature or voltage |
| External mechanical damage |
| Incorrect assembly or connection |
| Damage caused by cleaning with harsh agents |
| Normal front-end soiling |
Which luminaires are included: Orca, Snapper HC, Shark, Barracuda, Snapper, Marlin, Piranha, Goby, Goby Mini and the HT versions.
5year warranty
Five-year standard warranty on the complete luminaire. On fixed installations with periodic maintenance, such as terminals and site lighting, an extension to ten years is possible.
The ten-year extension does not apply automatically: it is determined per project and requires a fixed mounting position and demonstrable periodic maintenance. For mobile installations, where the DarkLicht Mini, S, and M are often placed, the standard term of five years applies.
| Housing | 5 years, extended by 10 years |
| Other parts | 5 years |
| Conditions | DarkLicht for Terminals |
At a fixed position, the load is predictable: no vibration from a moving machine, no changing mounting angle, and with periodic maintenance, contamination or coating damage is spotted in time. Under those conditions, we dare to go up to ten years, determined per project. On mobile equipment, the load is heavier by definition and the term remains five years; that is the same term as on the DCbright work lights.
| Housing, coating and bracket |
| Reflector optics and glass front |
| LED modules and lumen maintenance |
| Driver, intern or in the EXT-box |
| Extension up to 10 years for fixed installation |
| Extension without demonstrable periodic maintenance |
| Extension on mobile installations |
| Impact damage: the glass front is IK08 |
| Application outside temperature or voltage |
| Adjustment of the reflector or front |
Which luminaires fall under this: DarkLicht One, Two and Three, DarkLicht M, D, WP wallpack, DarkLicht S and DarkLicht Mini.
5year warranty
Five years, with additional conditions specific to the HT line.
The basic conditions below also apply to the HT line. The additional HT requirements are currently being drawn up and are not yet on the website; please request them with your application, and we will include them with the quotation.
| Housing | 5 years |
| Other parts | 5 years |
| Conditions | basic conditions; HT annex to follow |
At ambient temperatures up to +120 °C, the LED, the seals, and the silicone cable are operating near their material limits. For this reason, we impose additional installation requirements: the driver must be located outside the hot zone, the cable route must follow the specified temperature profile, and the burn time and radiant heat must remain within the specified limits. In these respects, the HT warranty is stricter than the standard warranty period.
| Housing, coating and bracket |
| LED modules and lumen maintenance |
| Remote driver in the DRB box |
| Silicone cable and grommets |
| Glass front, chemically tempered or borosilicate |
| Driver mounted in the hot zone |
| Ambient temperature above specification |
| Radiant heat outside the assessed scenario |
| A cable other than the included silicone cable |
| Use outside the assessed fire duration |
Which fixtures are included in this category: Orca HT, Barracuda HT, Snapper HT, Linear HT, and the HT models in 316L.
20year warranty
Twenty years on the stainless steel housing, five years on the remaining parts.
| Housing | 20 years |
| Other parts | 5 years |
| Conditions | Floodlights and work lights |
The housing is the part that must survive the corrosion, and 316L does not need a coating for that which could get damaged. That is why it has a twenty-year rating. The electronics, the seals, and the front are wearing parts with their own lifespan; the product line's period still applies to those. That distinction is intentional and is also stated as such in the terms and conditions.
| Stainless steel housing, 20 years |
| Bracket and mounting hardware made of 316 |
| LED modules and electronics, 5 years |
| Seals and cable entries, 5 years |
| Front, polycarbonate glass, 5 years |
| Corrosion caused by contact with another metal during assembly |
| Use outside the specified limits |
| External mechanical damage |
| Cleaning with agents outside the specification |
| Damage by unspecified substances |
Which luminaires are included: Orca, Barracuda and Snapper in 316L, the HT versions in 316L and the Piranha in 316L.
For heavy industrial use, within technical specifications
| Product line | Term | In response to | Conditions |
|---|---|---|---|
| DCbright floodlights and work lights | 5 years | the complete fixture | Floodlights and work lights |
| DarkLicht floodlights and work lights | 5 years | complete; 10 years possible with fixed installation | DarkLicht for Terminals |
| HT versions up to +120 °C | 5 years | complete, with additional HT terms | basic conditions; HT annex to follow |
| Versions in fully 316L | 20 years | housing in 316L; other parts 5 years | Floodlights and work lights |
The extension to ten years for the DarkLicht line applies only to permanent installations with verifiable periodic maintenance and is specified on a project-by-project basis. For stainless steel models, the warranty on the housing is 20 years; for the electronics, seals, and other components, the warranty period specified for the product line applies. The warranty applies within the technical specifications: use outside the design limits—such as at a higher temperature or a voltage other than that specified—is excluded.
Two documents, both available for direct download. They outline the term, what is covered, what exclusions apply, and how to file a claim for each product line.

Also required for an application or delivery: quality marks and certifications, datasheets per luminaire and the Terms and conditions.
The difference only becomes apparent under load. In practice, six conditions determine whether a luminaire achieves its specified lifespan; they are also the reason why we ask about the environment when receiving an inquiry, and not just the number of lumens.
A twenty-year warranty period is not a commercial promise, but a calculation of failure probability. That probability is determined in the factory: in the soldering method, the heat transfer to the housing, the cable entry, and the final inspection per luminaire. Below is an overview of what we do for each choice, which standard applies, and why it matters.
Long cable runs, generator power supplies, inductive loads, and mobile machinery cause voltage spikes and power surges. Eleven protection features are integrated as standard into the fixtures; they explain why failures due to electrical stress are rare in practice.
The dump load transient complies with IEC 61000-4-2 above level 4, with 30 kV air and contact discharge, and with ISO 10605, ISO 7637-2, and ISO 16750-2 tests A and B. The electromagnetic compatibility has been tested according to EN 55015 and EN 61547. The complete test series is listed in the datasheet per luminaire and is available as a report upon request.
Nine topics, 49 questions. Choose a topic; if your question is not listed, call Lucas de Graaf at +31 6 1054 4770.
That a luminaire continues to function reliably within the conditions for which it was designed. That goes beyond light output: material choice, thermal design, sealing, electronic protection, mechanical robustness, and suitability for the application determine this together.
Because lighting there has to deal with heat, moisture, dust, corrosion, vibration, voltage surges, and hard-to-reach locations. A defect then costs not only a fixture, but also downtime, a aerial work platform, safety measures, and planning.
No. A luminaire must suit the application. Sometimes coated aluminium suffices, sometimes stainless steel, a higher temperature class, or different electronics are required. The best solution is the version that is technically correct, not the heaviest one.
More robust housings, better heat dissipation, stronger sealing, higher impact resistance, better corrosion protection, and electronic protection. Everything aimed at long-term use under load rather than a low purchase price.
Because a technically sound fixture can still fail in the wrong environment. Temperature, corrosion, vibration, voltage, mounting position, and maintenance access also determine whether the fixture is suitable.
Within the technical specifications and conditions, yes. If a luminaire is used outside the design limits, for example at a higher temperature, a different voltage, extreme corrosion or incorrect installation, this may affect the warranty. When in doubt: have the application assessed in advance.
Because construction, material, and application differ. A stainless steel housing has no coating that can be damaged and therefore gets twenty years; a luminaire on a vibrating machine operates under heavier mechanical stress and lasts five years.
This is intended for permanent installations that undergo periodic maintenance, such as terminals and site lighting. The extension does not apply automatically: it is determined on a project-by-project basis and requires a fixed mounting position and verifiable maintenance. If the luminaire is mounted on mobile equipment—as is often the case with the DarkLicht Mini, S, and M models—the standard five-year term applies.
Five years, with additional conditions that specifically apply to the high-temperature line: requirements regarding the location of the driver, the cable route, the duration of the fire resistance, and radiant heat. Those conditions are currently being drawn up; request them with your inquiry, and we will include them with the quotation.
Warranty states the conditions under which a product is supported. Suitability is about whether the luminaire technically fits the environment. A luminaire can fall under the warranty and still be the wrong choice for your location.
Because inspection makes problems visible early: contamination, coating damage, cable damage, or mechanical stress. No periodic product maintenance is required, but cleaning the front and checking the cable entry during regular servicing is advisable.
Send a message to service@jelproducts.nl with the type designation, year of manufacture, mounting position, and photos of the fixture and the location where it is suspended. Your report will be evaluated by an engineer and you will receive a response within 1 business day.
The documents on this page are currently being revised. When submitting a request, please ask for the current version, or refer to the terms and conditions that were included with your quote; those are leading.
Yes, and we prefer to do that rather than arguing about it afterwards. For critical applications, we check in advance whether the luminaire remains within the technical limits under the site conditions.
Yes. Drivers, LED modules and front covers are available separately, even outside the warranty period. In most cases, this allows a luminaire to be repaired rather than replaced. On a mast, crane or offshore installation, this saves not only the price of a new luminaire, but above all the dismantling and reassembly at height. The serial number determines which version and which parts belong to it, so there is no doubt about what needs to be ordered.
We deliberately carry a limited number of products rather than a broad catalog, and that is precisely what makes long-term support possible. The Barracuda, our oldest fixture, has been supported continuously since its introduction in 2013. Drivers, circuit boards, and front covers have been improved over that time, but the new versions remain compatible with the older model. So anyone who purchased a fixture years ago can still order a compatible part today.
For high corrosion stress: offshore, maritime, coastal areas, chemical industry, food production, or locations with aggressive cleaning. The determining factors are whether the stress is permanent and how accessible the position is.
316L contains molybdenum and is therefore significantly more resistant to chlorides than 304. In the presence of salt, chlorides, chemical stress, or marine environments, it is the safer choice. Not every environment requires it.
Not by definition. High-grade aluminium with the right coating functions excellently in many industrial environments. Stainless steel becomes interesting as soon as the load is so high that a coating alone does not provide sufficient certainty, or when the coating can be mechanically damaged.
It protects the housing against moisture, dirt, UV, chemicals, and corrosion. The pre-treatment, layer structure, and application determine how long that protection remains effective; hence a chrome conversion coating followed by a double powder coat layer with titanium. The system has been tested with 1,000 hours salt spray according to ISO 9227 and complies with corrosivity class C5-M and C5-I according to ISO 12944. These are the heaviest standard classes for marine and industrial outdoor environments, respectively; for even heavier loads, we supply fully 316L.
Not the housing, but the edges: bolts, brackets, cable entries, connections, and coating damage. Corrosion protection must therefore be assessed as a complete system.
Yes, each luminaire individually: electrical operation, visual finish, sealing, and thermal behaviour, including a recording with a thermal camera.
Because a manufacturing defect that only becomes visible on site is much more expensive than the luminaire itself. With high masts, cranes, and offshore installations, repair requires a cherry picker, a shutdown, or a vessel.
Electrical and lighting performance, visual inspection, sealing, cable entry, strain relief, coating, lens quality, thermal behavior and finish.
That shows whether the heat is properly dissipated and whether components remain within their safe temperature range. That is decisive for lumen maintenance and lifespan, and it cannot be determined by the naked eye.
Yes. For projects, we coordinate additional controls, documentation, specifications, or inspection points based on the project requirements.
Yes. Every industrial fixture has its own serial number. This number is linked to the model, configuration, production date, QC batch, and warranty status—even years after delivery. So when a report is filed, we don’t have to reconstruct what was delivered—the serial number is all we need. That’s also why we ask for the model number and year of manufacture when a defect is reported.
The most important ones: IP rating according to IEC 60529 and ISO 20653 for IP69K, impact resistance IK according to IEC 62262, corrosivity class C5-M and C5-I according to ISO 12944 with a 1,000-hour salt spray test according to ISO 9227, lumen maintenance according to LM-80 with a TM-21 projection in accordance with IEC 62717, electrostatic discharge according to IEC 61000-4-2 and ISO 10605, transients according to ISO 7637-2 and ISO 16750-2, and electromagnetic compatibility according to EN 55015 and EN 61547. We supply the underlying reports upon request; the applicable standards are listed per luminaire in the datasheet.
The quality of LED modules, driver, thermal design, sealing, material, coating, electrical protection and assembly. In harsh environments, temperature, moisture, corrosion and vibration are often more decisive than the specified number of operating hours.
Because that figure applies under controlled conditions. High ambient temperatures, poor ventilation, voltage spikes, moisture, or corrosion greatly affect real-world performance. Therefore, always assess lifespan in relation to the application.
How much luminous flux a luminaire retains over time. LEDs rarely fail; they gradually degrade. L90B05 at 360,000 hours means that at least 95 percent of the luminaires will still provide 90 percent of their original luminous flux.
Insufficient heat dissipation, incorrect material choice, moisture ingress, voltage spikes, vibration, corrosion, poor sealing, driver overload, or application outside of specifications.
By selecting based on the actual application: ambient temperature, corrosion, voltage, vibration, mounting position, operating hours, optics, maintenance access, and electrical configuration.
How well a luminaire is protected against dust and water: IP67, IP68, or IP69K. Which class is needed depends on the cleaning method, moisture exposure, and mounting position.
Not always. IP69K is relevant for high-pressure and steam cleaning. Where that does not occur, IP67 or IP68 may be sufficient. The conditions determine the choice, not the highest number.
The impact resistance. IK10 is the highest class and represents 20 joules, comparable to 5 kilos from a height of 40 centimeters. Relevant where tools, materials, or machinery can hit the fixture.
Under heavy mechanical stress: cranes, mobile machinery, work sites, ports and production lines. On masts and facades, IK08 is rarely a limitation in practice.
Because they say nothing about thermal design, corrosion protection, electronics, lumen maintenance, or driver quality. A luminaire must be evaluated as a whole.
Heat accelerates the aging of LEDs, drivers, seals, and electronics. If it is not dissipated sufficiently, the light output drops faster and the risk of failure increases.
As soon as the ambient temperature, radiant heat, or mounting position falls outside the range of standard lighting: ovens, steel, glass, rock wool, and hot process environments.
Drivers are the most sensitive to heat. In hot zones, the driver should be located outside that zone, in a separate box. This reduces the thermal load and allows maintenance without entering the hot zone.
No. Radiant heat, air circulation, mounting distance, operating time, and contamination all count. A fixture may seem suitable on paper and still be overburdened by radiation or stagnant air.
That is designed for normal temperatures. In the heat, LEDs degrade faster, drivers become overloaded, seals age, and components operate outside their safe range.
Because voltage spikes, electrical noise, incorrect wiring, and long cable runs cause damage to drivers, LED modules, and printed circuit boards. The protections significantly limit that risk.
That cuts off the power supply as soon as the voltage goes outside the set margin and switches back on once it returns. This way, the electronics remain out of harm's way during a temporary deviation.
Protection of sensitive electronics against voltage spikes and electrostatic discharges on the connection wires, particularly relevant in industrial and mobile applications.
In DC applications, incorrect connection causes damage. An active system protects against this without the voltage drop and efficiency loss of a diode.
No. They increase operational reliability, but cable routes, power supplies, grounding, surge protection, and mounting still need to be correct.
Based on application, environment, mounting position, lighting requirements, voltage, temperature, corrosion, vibration, maintenance access, and any normative requirements. This results in a product family and a version.
Because the biggest costs in harsh environments are not in the fixture itself, but in installation, maintenance, failure, cherry picker rental, planning, and downtime. A cheaper fixture can therefore end up being more expensive.
More lumens does not automatically mean better light. Optics, mounting angle, glare, light distribution, and uniformity weigh just as heavily. A good solution starts with the distribution of the light, not the wattage.
As soon as standard product selection does not provide sufficient certainty: high masts, terminal sites, cranes, offshore, high temperatures, corrosive environments, or projects with requirements regarding light pollution, standards, or maintainability.
Yes. For projects, we look at the complete configuration: luminaire selection, optics, mounting angle and height, driver location, cabling, maintenance access, and electrical preconditions.
Warranty applies within the technical limits of the luminaire. If the temperature at your location rises higher than specified, the voltage is unstable, or the load is heavier than usual, we prefer to be told in advance. Sometimes that means a different version, sometimes a different luminaire.
