LUMEN refers to the total amount of light or light energy that is radiated from a light source. This does not measure the intensity of a bicycle lamp.  The intensity of the light depends on the direction. When the direction of the light is unknown it is impossible to calculate the intensity of the light.

Fig 01

Both LUX and CANDELA refer to the intensity of the light in a certain direction of the light beam.
CANDELA is equal in the total light beam, while the LUX-value depends on the distance of the light beam (FIG 02). In the FIG 02 the middle beam is 2000 CANDELA, while the amount of LUX is variable at different distances.

Fig 02

The formula between these two units is:

In most cases LUX is measured at a 10 meter distance from the light source. This means that the CANDELA-value can be calculated by:

As can be seen in all figures the light beam of a headlamp contains several areas with different amount of CANDELA and LUX to create an ideal headlamp for its purpose: TO SEE and TO BE SEEN.

When a headlamp claims to contain 20 LUX or 2000 CANDELA, this means that the brightest spot in the light image has 20 LUX at a distance of 10 meter (FIG 01 and 02). This amount of light is mainly directed at the road so oncoming traffic is not blinded by it (FIG 03).

Fig 03

The light in the blinding area should not be higher than 2 to 2,5 LUX* . In this area the amount of lumen is also lower (200 to 250 lumen).
For rear lights the CANDELA-value is used, since very small LUX values need to be measured here. Rear lights radiate inbetween 1 to 4 CANDELA corresponding to 0,01 and 0,04 LUX*.

“A headlamp is mainly made for the rider to see the road and eventual obstacles. Spanninga uses the unit Lux as a measure of the intensity of light, as perceived by the human eye, that hits a surface. So Lux gives some indication about the lighted area in a light beam.
A rearlight is made to be seen by other road users. Spanninga uses the unit Candela as a measure of luminous intensity; that is, power emitted by a light source in a particular direction. Candela says something about the intensity of the light source.”

In Germany the overall construction is checked and the light output and distribution is checked for either 10 lux or 20 lux.
In France the light distribution is checked for 4 lux.
In Netherlands a voluntary test can be done for a classification of 1-star (>4 lux), 2-star (>7 lux) or 3-star (>10 lux, checking of the light distribution and vibration resistance.
In Denmark a self-certification system is used where the lights are to be checked for light distribution and a centre value of 0,04 lux.


In Germany and France rear lights are checked for light distribution and if >2,5 cd in the centre.
In Netherlands there is a voluntary classification based on a star system, where 1-star is  >2cd, 2-star is >2,5 cd and 3-star is >4 cd.
In Denmark light are self-checked by the supplier for light distribution and if  > 4 cd.

For reflectors the differences are minimal. An ECE (like) reflector is accepted, except in Germany where the Z-type reflector for the carrier rearlight is required.

“To be able to sell bicycle lights which are allowed in road traffic, approvals are needed in several countries in Europe. Approvals give an indication about the light output and the general quality of the lighting product. Spanninga endeavours to follow the local rules in different countries in order to meet the legislation and the minimum safety requirements for bicycle lighting”.

Sparta logo

“Safety is crucial, so we pay a lot of attention to safety in respect of bicycles for adults and bicycles for children. This is an essential part of the briefing. In our opinion it is very important that the lighting is not damaged when the bicycle falls. Also very important is the fact that the lighting is always working, in twilight as well as in the dark! And finally, in the development of the SL-18 headlight not only did we pay attention to the quantity of light so that the cyclist could see very well, but also to the aspect of ‘being seen’. That’s why we gave our utmost attention to the visibility of the vulnerable side of the cyclist! Co-operating with Spanninga we know that we can count on expertise, gained over many years, which is not only impor­tant for the Netherlands but also for the countries where we export. Just look at the new headlight we developed together! With this design we prove that we are leading in that field. It is a must for Sparta to be a leader in several segments of the market. Spanninga really helps us to achieve this performance by developing new technologies and designs.” Sales Manager – SPARTA

Batavus logo

“Safety has always been an important issue for Batavus. In a country where people are always using the bicycle as often as in the Netherlands, in daylight as well as in the dark, in all weathers, good lighting is a must! Spanninga helps us to make our clients visible by offering the right products and thinks alongside us in the development of new products. Purchasing a bicycle is becoming more and more an emo­tional choice. An appealing design is of great importance. Batavus designs almost all their components themselves. Span­ninga helps us to transfer these designs in solutions which fulfil our quality and safety standards. Cooperating with Spanninga means a big advantage of design freedom. Spanninga is a company that is constantly trying to update their products. They come up regularly with new develop­ments which follow the latest lighting trends. Furthermore they know how to implement these innovations in our own designs. Our most recent line of headlights and rearlights is a good example of this way of working.” Product Manager – BATAVUS

“For the last couple of years we have developed several lights with Spanninga. The timeframe from the start of the development till the moment we needed the lights for series production was very short. We started by presenting our design ideas and Spanninga then played a big role in arranging the technical drawings. The process was best described as effective, well-structured and creative. We all knew that there was no time for anything to go wrong during the development. Spanninga convinced us from day one that they were able to meet our requirements and they succeeded in this far above expectations. We were confident of their capabilities to make it on time and this will be remembered for future projects. We are very satisfied with the knowledge and input of the whole team. After the introductions we have received nothing but positive feedback from both dealers and consumers. Spanninga did a great job. Purchaser – BATAVUS

Trek logo

“For Trek Benelux, as being part of a worldwide company, safety is of very great importance. As one of the initiators of the RAI-mark for bicycle lighting (RKF), Spanninga has proved to consider safety, like us, as a high priority. Trek has carried out several projects in which design and integration were important requirements. Spanninga was closely involved in the development of the projects and could easily meet the wishes of our designers and engineers. Spanninga is capable of delivering the right things to customers and to us as a bicycle manufacturer in the constantly changing lighting market.” Product Manager Benelux – TREK

Gazelle logo

“Safety is an important issue for us. Our lighting must meet what we call ‘robust quality’ with which ‘to see’ and ‘being seen’ is of great importance. This must last over the total lifetime of the bicycle. One of the brand visions of Gazelle is ‘smart design’. This provides us a great part of our distinctive position in the cycle market. So that is how we add value to our bicycles. Spanninga delivers a very good balance in price/quality and combines this for e.g. rearlights with good lightguiding technologies. Moreover they are leaders in the modular construction of their products.” Innovation Manager – GAZELLE

Moustache logo

“When working on the front light integration on our city model LUNDI 26 we were happy to find a reactive team and support of Spanninga. This gives a unique result and look to our products. We are also using the nice Pixeo on all our models. Minimalistic design, quality and efficiency at an affordable price. Great cooperation!”
General Manager – MOUSTACHE BIKES

Koga logo

“When we asked Spanninga to make us an offer for a new rearlight for one of our e-bike battery series, already in the beginning they surprised us with a working prototype to demonstrate their technology. During the project there was good collaboration between us and Spanninga R&D. They managed to translate our demanding design ideas into a good looking and well-functioning product. And on top of that they managed to do this in time. It was a pleasure to work with Spanninga in this project.” Product Engineer – KOGA

Scott logo

“Looking for a headlamp, integrated into the stems, we contacted Spanninga. The development with them was very smooth and quick! Communication went very well from the real beginning. The result is a light with a streamlined design which really fits the bike.” Product Manager – SCOTT

Union logo

“Union was looking for a fully integrated front and rearlight into the tube frame of our Union Lite bicycle. In the end, Spanninga designed a light exclusively for the Union Lite. It makes a perfect fit for the minimalistic design of this Urban bike. The great thing is that the light is easily plugged in or out, allowing Urban bikers to easily attach a front carrier to the bike, or any of the other modules. The users helped co-create some of the clever extensions for the bike, allowing Union to create the first modular bike, literally created by and for Urban bikers. Certainly also thanks to the partnership between Union and Spanninga we can speak of high-end Dutch Craftmenship.” Commercial Manager – UNION

Giant logo

“Lighting dreams come true with the stunning and exciting Prime E+ as a result of the collaboration between both Giant and Spanninga!” Product Manager – GIANT

The high quality of the Spanninga name in this field is rewarded by the satisfaction and the trust of our customers.

Spanninga’s design vision focuses on a strong link between technology and design. In most of our products, technology is not hidden but rather integrated into the design of the product and therefore displayed as a real asset. We are convinced that internal technical elements (like cooling elements, optical parts etc.) give another dimension to our creations and highlight the authenticity of our products.

SketchesOur approach to bicycle lights design is to maintain, in addition to the core functionalities of the product, clear and clean surfaces and limited control elements (like integrated switch or attachment).

The use of innovative combinations of materials (like brushed aluminum or stainless steel) and the selection of specific colour shades enhanced by the Spanninga icon contribute to a certain harmony to make it easier to distinguish our brand based on the design of our products.





Product quality and user safety are the 2 main commitments of our forward-looking group. Offering the best safety conditions means offering high-quality products to rely on. That’s why we provide a large range of products, all of them developed for specific needs and for an easy use.

Our lights, both front and rear, comply with this requirement by offering a great visibility. In order to determine the visibility distance of our lights, Spanninga has defined specific calculations linked to light illumination. In the same way, the battery lifetime of our products is measured until the light illumination reaches the minimum visibility level at 10m that we have determined, which is 0,25 Lux for front lights and 0,5 cd for rear lights. The visibility distance and battery lifetime of our products are clearly mentioned on our packaging.
Since its creation, the Spanninga Group has maintained the highest standards of quality control in order to satisfy continuously customer needs and expectations.

Quality tests

From the development phase until their launch on the market, all our products go through a number of tests that have been carefully defined in our quality policy:

–       Photometric values are regularly measured to make sure the light output and visibility meets our expectations and the regulations we apply for,

–       Shock resistance tests are carried out to ensure the best use of our products in all kinds of conditions (vibration and crash tests, temperature tests, UV, moisture and corrosion tests, durability tests, etc.),

–       Water resistance is controlled to achieve the IPX3 rating (protection against spraying and splashing water).


User friendliness also means quality; that is why we are very attentive to the battery consumption during the conception phase. Our development team gives priority to technologies offering very low battery consumption in order to offer the longest time of use of our lighting products. We also pay great attention to the quality of the batteries we use and mainly supply our products with high-performance batteries.
