Outdoors, 10,000 to 100,000 lux is quickly on your eyes. Indoors, the standard is 500 lux, and only 250 lux reaches the 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 opinions that this quantity of light does stimulate our biological clock in the morning and afternoon.

In the evening, there is little warm light outside, which makes Sparckel.

The mechanism in the brain responsible for regulating the circadian rhythm is called the biological clock. This mechanism is located in a core area in the hypothalamus called the nucleus suprachiasmaticus. Light striking the retina of the eyes is transmitted via special ganglion cells to the hypothalamus and from there to the suprachiasmatic nucleus. These ganglion cells contain the light-sensitive pigment melanopsin. The suprachiasmatic nucleus regulates the rhythm of wake-sleep by stimulating other brain areas such as the epiphysis (pineal gland). The epiphysis produces the hormone melatonin, which influences 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 special Led integrated on a circuit board. These cannot be replaced.

The clock function is integrated. Even when the plug is not in the socket, the clock continues to run, summer and winter time included. There is even a seasonal clock that, based on geo-location (longitude and latitude), knows to the minute what time the sun rises and sets. We can adjust our light scene accordingly. In winter, the activating part of the light 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 easily 7 years with regular use. To achieve this, we use our aluminium lampshade with light slots to keep the LEDs well cool.

Two years full warranty, provided normal use. See also our general terms and conditions.

We can extend the standard 2-year warranty to 5 years at a charge of €75 ex VAT.

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.
