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.
