Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the screening attentuation report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the ULTRA performance class, the focus is on MAXIMUM. Only highly developed shielding materials create our metrological requirements for the SFERICS® ultra classification. When every single dB counts!

Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the umbrella report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the PRO performance class, the focus is on HIGH. Purely highly developed shielding materials create our technical requirement for a SFERICS® pro classification. When above-average shielding is the goal!

5,5 watt LED G9 | bright as 41 watts, 485 lumens | CRI 95 | flicker-free | warm white | alternative to high-voltage halogen G9
LED G9 lamps with 5,5 watts in this quality class are state-of-the-art in lighting technology and are highly recommended in terms of building biology. Corresponds to the light output of a 41 watt high-voltage halogen lamp.
This LED G9 produces a friendly and natural, warm white light, can be operated with any G9 socket and is almost flicker-free. The reading of the pulsating light is less than 1 percent.
Delivery time: approx. 1-3 working days | formerly energy class A+
5,5 watt LED G9. A feel-good light close to nature in the size of the previous G9 high-voltage halogen lamp. “Flicker-free” light quality with a high CRI 95. Not dimmable.
The almost continuous spectrum of the emitted light is close to that of halogen lamps, but without the proportion of thermal radiation (IR or infrared radiation). This G9 LED produces a uniform, sunlight-like feel-good light in which the flicker content has been reduced to a minimum of < 1 % – an ingenious replacement for the previous halogen G9 light source.
Instead of the halogen bulb ban in September 2021 or September 2023, it is now possible to switch to this new G9 LED model, which is healthy from a building biology point of view. For further information, please visit:
The colour rendering index (Ra or CRI) describes the effect of light on the colour appearance of objects by comparison with daylight (not dependent on colour temperature). Incandescent lamps have a very high CRI of up to 100, this LED achieves the incredible Ra or CRI of 95. The higher the CRI is at 100, the more natural and real colours are.
The colour temperature is a measure of the respective colour impression of a light source. Warm light colours (warm white, 2700 K) have a low Kelvin number, cold light colours (cold white, 5000 K) have a high Kelvin number.
The light exit angle of 360º is very well suited for all applications where incandescent lamps have been used up to now. Ideal for lighting an entire room as all-round light.
LED lamps are made of a semiconductor and operated with an integrated ballast. The resulting voltage generates “light flicker” (pulsation). This pulsation could be reduced to a minimum (below 1 %) with the “filament” LED.
Electrosmog: This LED was designed to generate small technical fields comparable to those of a halogen bulb.
LED G9 5.5 watt bulb, flicker-free (< 1%). Replacement for halogen G9 bulb.

The new EU energy label since 2021
The new EU energy label for light sources, which will apply from September 1st, 2021, not only looks different, it is also based on new, stricter classification criteria. As a result, lamps and lights are classified in lower energy classes. However, nothing has changed in terms of the power consumption of the lamp.
– For luminaires with existing G9 base.
– Suitable for many shielded Biologa Danell luminaires.
– For use in all luminaires with E14 or E27 socket with G9 adapterNot suitable for luminaires of the Biologa Danell series light shower (41-8803, 41-8904, 41-8882, 41-8904, 41-8926), salt crystal luminaire (41-6226)
Scope of application
– All private living spaces
– Public buildings, hotels, office buildings

Pay attention to healthy light when buying lamps!
Healthy light from a building biology point of view, is a light source modelled on the sun
without flickering, as close as possible to 0 Hz (Hertz)
a light spectrum/colour spectrum that is as close to nature as possible, without the predominantly much too high proportion of blue light in an LED, for example. This serves to protect the macula (prophylaxis against premature macular degeneration).
Day-adapted colour temperature, i.e. full spectrum during the day and warm light in the evening.
