Engineering & Customization

from custom light color to completely new fixture

We design, test, and build lighting for environments where no standard product exists. Fourteen meters underwater. From -65 °C to +120 °C. Fully 316L stainless steel. Lead glass that withstands gamma radiation. Every claim on this page has been tested and verified.

How far does customization go at JEL?

14 meters

underwater

Permanently submerged and resistant to the pressure differential at depth. There was no fixture for this application, so we built one, including a pressure-resistant seal and cable gland.

Flake glass

against gamma radiation

For a European nuclear facility, we developed a luminaire with radiation-shielding lead glass in a 316L housing. The product exists, has been delivered, and is performing its function.

316L

all stainless steel

For chemistry, offshore, and salt-laden environments, we build luminaires entirely from 316L, housing and fasteners. No coating that can be damaged, but material that can handle it itself.

-65 °C to +120 °C

Temperature range

From arctic cold to the radiant heat of the process industry: we select and test every component: LED, driver, seal, coating. All across the full temperature range of your environment.

Three levels of customization
You never pay for more engineering than you need

Level 1

Configuration

Existing fixtures, tailored to your application: light color, optics, CRI, voltage, cable length, connectors, brackets, and coating.

For whom: the correct specification without compromise within the standard delivery time. Consider amber 2200K with asymmetric optics for a nature-sensitive location.

Level 2

Custom fixture

Existing fixture structurally adapted: different housing, different material, additional sealing or supplementary certification.

For whom: environments where the standard just isn't enough. Consider the Barracuda with a heavy-duty bracket rated for 200G shock loads. Or a 316L stainless steel housing designed for high temperatures.

Level 3

Brand new fixture

From requirements to certified product: designed, prototyped, tested, and mass-produced for your environment.

For whom: environments for which no product exists: underwater, nuclear, extreme temperatures. Such as the 316L fixture with gamma-radiation-resistant leaded glass.

Are you unsure what level your situation requires? Describe your environment, and an engineer will tell you within one business day what is needed, and just as honestly when a standard product is sufficient.

From requirements specification to certified luminaire in five steps

Lighting where gamma radiation destroys every standard fixture

Electronics and plastics degrade under gamma radiation. Therefore, for a European nuclear facility, we developed a fixture with radiation-shielding lead glass in a completely 316L housing, designed for the radiation load at the installation site. Due to the nature of the location, we do not name the client; discretion is part of the work on these types of projects.

A fixture that just does its job 14 meters underwater

At a depth of 14 meters, every seal is permanently under pressure. We designed a fixture that is not only resistant to this, but performs for its entire lifespan, including a pressure-resistant cable gland and a serviceable design.

From Rolldock to Tata Steel and Boskalis: companies with the toughest environments choose our engineering. Not because of a brochure, but because of fixtures that demonstrably deliver what we promise.

Frequently Asked Questions about Engineering and Customization

From one piece upwards. For single pieces, a one-time engineering fee applies; after that, we build the fixture with the same testing and documentation as a series. Some environments require exactly one unique fixture — that's also possible.

Level 1 configurations usually fall within normal delivery times. A completely new fixture is project-dependent; after the requirements analysis, you will receive a concrete schedule.

Yes. Every specification on this page — water depth, temperature range, material, radiation shielding — has been tested and verified. We provide test reports as part of the documentation.

We will agree on that in advance. Exclusivity for your application or industry is negotiable.

Yes, we do that regularly — including for nuclear environments. Discretion is a given for these types of projects.

The same five-year industrial warranty as on our standard products, unless the application requires different arrangements.

Yes. We also provide lighting calculations, glare, and light nuisance reports in accordance with the NSVV code of conduct, as substantiation for your permit or design.

The more extreme the conditions, the more we like to hear it. An engineer will respond within one business day with an honest assessment: configuration, adaptation, or completely new design.
