Right light. Right place. Right time.
Simply choosing the right LED desk lamp won’t make a chronic insomniac sleep like a baby, but the right kind of light helps us to work and rest as nature intended. Quality light comes from a lamp that works with the human body. Most office lights don’t do that. They’re too bright or too dim, too cold or too warm, and too inflexible to meet our diverse needs. LUCTRA LED Desk lamps, on the other hand, can be tailored to fit individual preferences. Their award-winning design focuses on real human beings whose health and wellbeing depends on having quality light.
From the rising of the sun
Active in the morning; relaxed in the evening.
Wellbeing and productivity.
To the setting of the sun
Stabilized circadian rhythm.
In hours of darkness
Longer and deeper sleep.
Make light work for you, not against you.
Proven to be biologically effective, a LUCTRA LED desk lamp replicates almost the full spectrum of daylight. It synchronizes with our daily rhythm. That makes us more productive. The LUCTRA Table Pro’s flexibility goes beyond adjustable light intensity and colour temperature. Five hinges and pivots allow you to focus light in exactly the right place, whether for task lighting at a desk, reading in an armchair, or working at a drawing board. With 185° of rotation in the lamp head you can even turn it into an uplighter.
The outstanding performance of a LUCTRA Desk Lamp does not come at the cost of refined design. Available in white, black, or aluminium, the Linear lamp’s minimalistic lines and the Radial lamp’s round head both belong to a finely engineered product that enhances any working environment.
Despite their tiny power consumption, even the entry-level Linear and Radial lamps offer 1,000 lux performance with temperature and intensity adjustment. Ultimate flexibility and performance comes from the deluxe Linear Pro and Radial Pro models, which add stepless adjustment, longer reach, a boost function, and app control to the standard specification. With the Pro models you can also choose between three mountings: a solid base, a pin mounting, or a desk clamp, which can also serve as a wall mount.
Simple light control
There is not much point in an advanced lighting system if it is hideously complicated to operate. It’s always good to “read the manual” (which you can download here), but LUCTRA’s intelligent VITACORE® electronic system is so simple that you might not need to. The unobtrusive lamp controls only become visible when needed and universal symbols make them appear instantly familiar. You can step the brightness and colour of the light up or down just by tapping the touch panel.
The Pro models offer even greater precision. The boost function gives maximum light intensity for 30 minutes. Two USB connections also allow you to charge smartphones, tablets, or other USB devices.
The VITACORE® app allows you to set the colour of your LED desk lamp temperature anywhere between 2,700 and 6,500 Kelvin and to set the brightness exactly where you want it. Answer five simple questions when you install the app and the light will smoothly adjust the colour temperature throughout the day to match your routine. You can download the VITACORE® app for Apple devices from the itunes store, or if you’re using Android visit Google Play Store.

Maintaining your body clock
Too much of the wrong kind of light is no better for us than too much of the wrong kind of food or constant inactivity. Good light, coupled with a healthy diet and regular exercise, helps us to keep well. Light synchronizes our inbuilt body clock and the cells in our body to a daily cycle known as the circadian rhythm. We feel more alert when daylight alerts our brains to produce less of the sleep hormone melatonin.
Anyone who has experienced jet lag knows how it feels to have our circadian rhythm disrupted because our bodies are thrown into a different day-and-night rhythm. The same thing can happen without ever stepping on an aeroplane. Constantly going against our internal clock through night working or ‘social jet lag’ can have serious health effects, such as depression or diabetes.
Human-centric LED lighting can help stabilize our biological rhythm because it gives the body light signals which set its internal clock. Cold-white, blue-enriched light wakes us in the morning and warm-white, red-enriched light signals us to relax. Consistent use of LUCTRA’s® biologically effective artificial light can have positive long-term benefits.

LUCTRA LED Desk Lamp Design and Research
Professor Günter Horntrich, designer of LUCTRA Perfect Day Lights, founded his design agency in 1973 with a focus on industrial design in Pforzheim (Germany). In 1985 the company became known as “yellow design” and expanded into packaging and Corporate Design. Prof. Horntrich is also a lecturer in Design and Ecology at the Cologne International School of Design. Other clients include BMW, GSK, Henkel, Motorola, and Rolls-Royce.
Sleep researcher Dr Dieter Kunz conducted a sleep study, which demonstrated the biological light effect of LUCTRA lamps. You can download his 28 page report here or listen to him talk about the effect of light on our body rhythm in the video on the left.
The technology in the LUCTRA LED Desk lamp comes from a research project by Dr Ulrich Kuipers, a professor in the Department of Electrical Engineering and Information Technology at the Fachhochschule Südwestfalen.
What reviewers think
The German Design Award made the LUCTRA LED Desk Lamp 2016 winner in the lighting category for Excellent Product Design. In 2015 the same lamp won the Interior Innovation Award.
Designer and Lighting Expert Interviews
Birgit Gebhardt (Trend Expert): When I talk about not just function but also emotion light becomes a decisive factor because it addresses both aspects light has functional qualities and at the same time serves emotional needs by adjusting light according to mood. There is more and more scientific evidence that indicates that alternating lighting situations throughout the day like daylight or the simulation of daylight with sun and clouds stimulates my subconscious to such an extent that I can work with greater concentration and more efficiently. I can pick things up more easily.
Dr Dieter Kunz (Head of Somnology Department at St. Hedwig Hospital): The lighting scenarios that we have today have nothing in common with what we’ve been designed for over the last four million years. Then we had up to 100,000 lux outdoors; today we receive perhaps one promilla, but not much more and the body has not yet adapted to this. That means that many of us live during the day in biological darkness. On the contrary we receive illumination at night which our system recognizes as light and then the circadian system does not know what time it is and is confused. Many of us live in a kind of shift workers syndrome without working shifts at all. This truly offers a great opportunity for artificial lighting in the future so that we can enhance health and improve performance using optimized lighting scenarios.
Prof. Dr. Ulrich Kuipers (Engineering and Communication Technology at University of Applied Science South Westphalia): Everyday life will be impacted extremely because we will not just use light for seeing but we will be utilizing the physiological effects of light. Physiological effects of light can be explained as follows, by the share of blue light the production of important hormones like melatonin. This is the sleep hormone and serotonin which is also called the happiness hormone can be influenced effectively. This is done following the example of nature because we don’t want to interfere somehow, but we want to bring the light of a beautiful sunny day into the offices. The physiological effects of light that we want to utilize are, for example, activating light in the morning by high shares of blue light. At noon and during breaks when people want to relax, the share of blue light is reduced like having some clouds crossing the sky, or the ceiling in this case, when everybody is taking their break. In the evening for relaxation we will terminate blue light completely. This means that the sleep hormone melatonin is being produced as is the case with natural light. We are then able to relax and calm down and to prepare for the night or the next day.
Prof. Gunter Horntrich (Designer, yellow design Cologne): One of the great topics that has influenced the design always, and my colleagues all over the world for years actually, is light. I know that I always had big stomach ache if one of my students said I do a lamp because theoretically I can light up everything, like a watering can. I can light some paper clouds. But in the broadest sense possible, these are stylings and objects that exist in thousands of variations. On the other hand I have to consider what light actually is and if I think about light as a designer I also have to consider what shadow is about, and if I know what a shadow looks like, then probably I’m able to create light. There are many different kinds of light. It does make a difference if I light a whole office or if I place them in my living room. That means the physical condition of the application changes. There is no universal light for everything. The specialization of light implies a certain kind of light production. We started with a candle and now we are at LED, and most probably laser will appear soon. This also means that the source of light is changing which is a beautiful platform to act upon with design, in order to tease out what actually is the ultimate in this light, the very speciality in this light.
Birgit Gebhardt (Trend Expert): On the one hand we have a significant lack of skilled workers. On the other hand we see companies trying to increase efficiency by cutting office space, reducing the number of workplaces or joining workplaces in open space officers and so forth. I’ve been marked in a highly competitive job market it is not helpful to just reduce on quantity without improving quality because employees immediately figure out that such reductions are cost-cutting measures and fear that this will affect them as they assume that personnel costs will be cut. Companies have to balance this with quality enhancements to signal that employees do matter. That means that the furnishing of the smaller office space should be designed in a way to demonstrate appreciation.
Prof. Dr. Ulrich Kuipers (Engineering and Communication Technology at University of Applied Science South Westphalia): With increasing age, the eye’s lens becomes cloudy. Blue spectral light is transmitted and absorbed by the retinal ganglion cells to a lesser extent. Such things can be compensated by individual illumination as discrete workplace lighting is able to provide. We will provide more special blue light for elderly employees enabling them to manage the light according to their personal well-being.
Dr Dieter Kunz (Head of Somnology Department at St. Hedwig Hospital): For you the light is not sufficient for me it is because I am well illuminated meaning that I get a high level of illumination intensity of even colder white light. This is the kind of light which I need around this time of the day. On your side you are sitting in darkness and that light is definitely not sufficient. This is a factor for future development because we are not designed for sitting in rooms with artificial lighting, a light which is just one thousandth of what we’re actually designed for.
Prof. Gunter Horntrich (Designer, yellow design Cologne): Every designer would love to make a classic. Classics cannot be made. They evolve over time. Only after a few years is it decided whether this product becomes a classic or not. Otherwise it will be rather simple. Everyone would make a classic.
