Every product leaving Deltalight's factory undergoes rigorous testing to ensure functionality, aesthetics, and safety. Our accredited test labs adhere to international standards and feature state-of-the-art equipment, ensuring comprehensive quality assurance. This meticulous testing process guarantees that our customers receive products that have been thoroughly vetted before approval.

Reliable product quality

Deltalight's reliable quality isn’t something that just happens with the flick of a switch. It’s based on advanced development techniques such as 3D printing, FMEA (Failure Mode and Effect Analysis), goniophotometery, and internal safety and reliability tests. This guarantees a fast, efficient development process that gets it right the first time, which fits with our philosophy of keeping the path from idea to market as short as possible.

In-house lab with ISO 17025-certification 

Testing product quality and safety according to international IEC standards is done in our own certified Deltalight laboratory. Also thanks to the close cooperation with our testing partner SGS-CEBEC, we can guarantee that we meet the ISO 17025 standard for laboratories. This enables us to present CE, ENEC, and CB test marks for Europe and the IEC member states. Intertek's level 4 approval also allows our lab to test products for the North American market and to issue a cETLus seal of approval for our products. SGS-CEBEC and Intertek are independent bodies that guarantee the reliability of lab tests through their third-party audits. If this sounds about as understandable as doctors speak, suffice it to say that we take product quality testing very seriously.  

Photometry (Optics)

The light output, energy consumption, and light distribution are key ingredients for a good lighting fixture. At Deltalight, we have the knowledge and infrastructure to check the characteristics of the light distribution and to optimize the efficiency of the fixtures. Because we like to stay light years ahead in terms of innovation, our lighting laboratory is ISO 17025 accredited by BELAC/ILAC for the LM-79 standard. 

Together with light distribution, the quality of light is very important: light color, color rendering, uniformity, UGR... We use RIGO equipment to check and optimize the quality of the light source and the entire fixture in detail, in accordance with our Deltalight standards, which by this point you must appreciate are very high.

Optical simulation technology

We’d like to shed some light on a particular subject: superior light quality testing. Light quality also depends on components such as the optics, lenses, and reflectors used. Our optical engineers use (among other things) digital simulation in their research and development. This enables us to optimize the shape and position of the optical elements at an early stage in the design process. We can accurately estimate how the light fixture will perform once it’s ready to go. In addition to simulating the final effect, we also use optical simulations to optimize the energy efficiency and to see what the effect will be when we adjust the design.

Electromagnetic compatibility tests (EMC)

In addition to safety, reliability, and lighting quality, our lighting equipment must also comply with internationally imposed requirements for electromagnetic compatibility. EMC tests according to the relevant IEC standards guarantee this. They’re the ones who light a fire under us to make sure there is no interference between our lighting equipment and the environment.

Quality control and production tests

At various stages of production - from the moment parts see the light of day to the point where finishing touches are put on the final product - routine tests are carried out for functionality, safety, and aesthetics to ensure the highest level of quality. After assembly, each light fixture undergoes a final inspection. During this inspection, the electrical and functional operation of each individual device is checked, as well as its safety and finish. Only then are the products packed, labeled, and ready for transport. 

Our inspection partner SGS-CEBEC also guarantees that we always comply with the quality management system of the IECEE CB Scheme. We hope this quality assurance guarantee makes you see us in a favorable light.
