Healthy light inside
Sparckel is not just a daylight lamp, but a biodynamic one. This means that Sparckel ensures that you get the right amount of light at all times of the day. This is essential at a time when we spend more time indoors than out.
How it works
Sparckel is dynamic daylight. That means that you plug it in and then enjoy the sun all day long, but inside. But you can also operate it yourself using the control ring. A positive effect on your energy level, your mood and your sleeping behaviour. With all the consequences!
Jolly James has its healthy lighting technology in the form of a designer lamp. It has six LED groups that are controlled by time. So there is a clock in it that 'tells' the LEDs when to emit their light. So there is activating cold white light, normal warm white light and atmospheric amber light. In addition to direct light, the light is also diffused indirectly via the ceiling. This gives better light distribution which is more pleasant for our eyes. The LEDs are high-quality and energy-efficient.
The dynamic daylight goes 'naturally' from a morning light, to an activating afternoon light to increasingly calm and atmospheric light in the evening.
1.This light-transmitting shield has a hole pattern for cooling. Together with the indirect light, this makes a sparkling pattern on the ceiling.
2.This all-aluminium hood makes Sparckel reliable, as there is an airflow that keeps the electronics cool.
3.The PCB has LEDs that shine upwards and downwards. Together, they have up to 6,500 lumens of serious LED power. With a total of six LED groups, there is a wide ranging spectrum from 6,500 to 1,800 Kelvin. All intelligence is integrated Plug & Play: via proper cooperation of LED drivers, storage, microprocessor, clock function and software, light scenes play themselves out automatically.
4.The high-end shielding has nanotechnology tiny spheres. These are woven into the 'milk-glass-like' plate. This refracts the light several times, giving an optimal diffuse light image. Pleasant and comfortable for our eyes.

*Measured output of luminaire, this is lower output than source due to use of diffuser for visual comfort.
** The MDER indicates how effective a lamp is in activating the human biological clock (so-called non-visual aspects of light) compared to daylight. The higher the MDER, the more the light source will activate the human biological clock at the same amount of photopic lux.
The LEDs are specifically chosen for their properties to best approximate the colour composition of the sun, with a blue peak around 480 nanometres to thus excite your biological clock at the right time. Eulumdat files available to lighting designers.
