How dynamic daylight works
Sparckel is dynamic daylight. That means you plug it in and then enjoy the sun all day long, but inside. You get the right light automatically, but it can also be controlled with our control ring. A positive effect on your energy level, your mood and your sleeping behaviour. With all the consequences!
Our biological clock is out of sync
Did you know that despite windows, we quickly run out of light in buildings in summer? Buildings simply block a lot of light for humans. We can see and perceive just fine, but our biological clock is used to something completely different...
The power of outdoor daylight. Many times stronger than the light we experience when we are inside, many times stronger than regular artificial light.
Because we spend about 90% of our time indoors, our biological clock does not receive sufficient daylight stimuli.
That is disastrous for our health
Your biological clock is the master clock that controls almost all the cells in your body. This includes your day and night rhythm. This rhythm keeps all organs, including your brain, in a natural condition.
The dysregulated biological clock causes your internal body processes to get out of balance, for example our sleep hormone (melatonin). During the day, you feel tired and lifeless, and at night you actually have trouble falling asleep.
And sleep is one of the most important things for your health. And a lack of sleep increases the risk of brain diseases such as dementia, depression, burn-out, cardiovascular disease and obesity.
How much light do we need on our eyes?
Sufficient healthy light restores the rhythm of your biological clock. Light is expressed in lux. We need 1,000 lux during the day, which is roughly 4 times more than we get at the office and 10 times more than at home. In the evening, we need light that is warm and amber, like a setting sun. At night, darkness is important.
Our distant ancestors received, not so very long ago, 6 hours of light outside. Our biological clock needs 4 hours of daylight. Blue morning light in particular wakes us up and resets the biological clock. This happens after only half an hour of light.
- Towards 1,000 lux on your eyes
- Blue light during the day, warm light in the evening and amber light just before going to sleep
- The timing inspired by the sun outside.
- Light scenes for care, work, home and night.
- The angle of light on our eyes is natural, being from above, for better eye-comfort and effectiveness.
How does Sparckel ensure sufficient light?
Professional technology in a recognisable shape. Sparckel strikes a balance between many efficient LEDs with high power and good colour properties, with reliable cooling, an optically favourable light distribution and a simple operating ring. All with the aim of making our biological clock more synchronous with nature.

The light that makes you feel alive. We don't say this light light light light light light light light lightly, after two weeks you will already notice a difference in your sleep and your energy. Your mood improves immediately. How beautiful is that!


Frequently asked questions
Outside, there is quickly 10,000 to 100,000 lux on your eyes. Indoors, the norm is 500 lux and only 250 lux hits your eyes. This creates 'biological darkness' even though we can see. With Sparckel, we are making towards 1,000 lux on your eyes. We know from science and the latest expert insights that that amount of light is well our biological clock excites in the morning and afternoon.
At night, there is little warm light outside, which makes Sparckel at night.
The mechanism in the brain responsible for regulating circadian rhythm is called the biological clock. This mechanism is located in a core area in the hypothalamus called nucleus suprachiasmaticus. Light falling on the retina of the eyes is directed via special ganglion cells to the hypothalamus and from there to the nucleus suprachiasmaticus. These ganglion cells contain the light-sensitive pigment melanopsin. The nucleus suprachiasmaticus regulates the wake-sleep rhythm by stimulating other brain regions such as the epiphysis (pineal gland). The epiphysis produces the hormone melatonin, which affects the sleep-wake rhythm.
Believe us and know that even then more daylight will make a substantial difference. Compare it to top-class sport. Daylight gives you up to 12% percent extra performance, enough to successfully respond to changing challenging conditions at work.
No, Sparckel has all the special Led integrated on a circuit board. These cannot be replaced. The technical lifespan stands at 10 years of intensive use.
The clock function is integrated. Even when not plugged in, that clock continues to run, summer and winter time included. Even a seasonal clock is possible. We can set our light scenes accordingly. In winter, the activating part of the light then rises later, and sets earlier.
Yes, we can turn it on. There is a seasonal clock that knows exactly what time the sun rises and sets based on geo-location (longitude and latitude). We can adjust our light scenes accordingly. In winter, the activating part of the light rises later and sets earlier.
The expected technical lifetime is 10 years with intensive use. To achieve this, we use our aluminium lampshade with light slots to keep the LEDs well cool.
Three-year full warranty, under normal use. See also our general terms and conditions.
We can extend the standard warranty to 5 years for a fee.
Yes, you can. Try to be outside as much as possible, also during work, for example at lunch time. Not only get a breath of fresh air, but also a light.
No, Sparckel makes much more light. The light output of those regular smart lights is insufficient at 800 lumens for our biological clock during the day. Sparckel makes up to 10 times more light and it is well designed both optically and in terms of cooling.
The smart lights use so-called RGB LEDs. We are mainly in the full white spectrum.
In addition, we have integrated special healthy lighting scenes based on scientific findings and feedback from existing customers.
