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!

8 watt LED full spectrum DuoLight | 3 light colors with a click: daylight + warm light + neutral light, 700 lumens | CRI 95 | flickerfree | E27 | business quality
LED full spectrum DuoLight with 12 watts and 3 light colors, i.e. easy change of color temperature with a click between daylight, warm light and neutral light. The daylight produced in this quality class is state-of-the-art in lighting technology and is highly recommended in terms of building biology.
A light experience that is as close to nature as possible, based on the model and light spectrum of the sun. The measured value of the pulsating light is less than 1 percent.
Delivery time: approx. 1-3 working days | formerly energy class A+
8 watt LED full spectrum DuoLight with E27 socket. A natural daylight with a high color rendering CRI 95 and almost “flicker-free”. 3 light colors in one lamp: daylight + warm light + neutral light. Suitable for continuous operation.
Yes, the name DuoLight is misleading and does not do justice to the actual effect. 3 in 1 is the true power of this incredible LED bulb. Depending on the situation, simply switch.
In addition to the full spectrum daylight produced, this LED DuoLight impresses above all with the latest lighting technology. Only one lamp for maximum natural light experience, based on the model and light spectrum of the sun. Daylight at 5400 Kelvin, neutral white at 4000 Kelvin and cozy warm white incandescent light at 2,900 Kelvin color temperature in the evening. Switching neither with bus nor Smarter App. Simply by means of a light switch on/off on the wall.
LED DuoLight is flicker-free!
Sunlight does not flicker ie. flicker-free at 0 Hz (Hertz). Developed on the model of our sun, this LED DuoLight is also maximally flicker-reduced, i.e. healthy flicker-free also according to building biology guidelines. This LED produces 700 lumens of luminous flux at a brightness of 80 watts.

LED DuoLight: Sensational lighting technology modeled on the sun
This high-tech LED DuoLight impresses not only with the unique choice of color temperature depending on the application, but above all with its very high color rendering and flicker-free light. The color rendering index CRI is an incredible 95, which enables colors to be seen very closely to nature. When switched on, the LED always lights up with full-spectrum daylight; a short switch on and off with the switch then changes the light color.
Switching mode 1: full spectrum daylight (5,400K)
Switching mode 2: full spectrum warm light (2,900K)
Switching mode 3: full spectrum neutral light (4,000K)
The LED always starts in switching mode 1.
If you press the light switch again – change to switching mode 2.
The same thing is repeated – change to switching mode 3.
The maximum time span from switching off to switching on again is one second. Confirming the light switch 5 times in a row (ON – OFF – ON – OFF – ON) switches directly to switching mode 3 with 4000 Kelvin, for example.
Switched off after 10 seconds, the LED jumps back to switching mode 1 with full-spectrum daylight.
LED Duolight: Convincing performance at a glance
We at SFERICS use this illuminant LED Duolight in the office as well as in the private living room. Even after many months of use, we are still fascinated by the light produced. We experience similar reactions every day with people when they experience this quality of light for the first time, followed by the measurement result of the lamp switched on.

FULL SPECTRUM LAMPS – THE HEALTHIER LIGHT
Our near-sun full spectrum daylight lamps support your natural vision and health in many ways. This is because their spectrum is very similar to sunlight. They therefore achieve similar supporting effects as the sun. The most important advantages for you are:
More well-being
High contrast viewing of small fonts
See and distinguish natural colours
Fewer eye problems
Less tired
Concentrate longer
More capacity
FOR THEIR ILLUMINATED EVERYDAY LIFE THIS MEANS:
Awake longer
Feel better
More concentrated
More relaxed eyes
The benefits of the LED light DuoLight
Simple switching from fresh full spectrum daylight to cosy “bulb light”. With this full-spectrum LED lamp you can enjoy the sunny full-spectrum light and, if required, switch to a cosy “bulb light”. For you this means: seeing, recognizing and comparing colors naturally, less tired and better concentrated. For cosy laps you can then simply switch on the warmer bulb light with 2900 Kelvin. Low heat generation and a beautiful fresh, clear light for beautiful natural lighting in the living area and at work. When switched on, this LED lamp immediately lights up with full brightness.
Examples of use
As an LED lamp (without mercury) with E27 socket, it can be used wherever you have previously used incandescent lamps or normal LEDs. For example for lighting in the kitchen, at the dining table, in the living room, in the children’s room, in the hallway, in the bathroom, in the utility room, the reading corner, at the desk, etc. – actually everywhere where you like bright fresh light and want to have natural lighting.
Easy mounting
Just screw it in and you’re done. Fits in anywhere where you have previously used a light bulb/bulb.
Brightness
The brightness of this full-spectral LED lamp corresponds approximately to that of a 80 watt incandescent lamp.
Supplementary information and notes
This LED full spectrum daylight lamp, with a consumption of 8 watts, has already paid for itself within 1,400 hours despite the higher acquisition costs due to the low energy consumption compared to a 80 watt bulb!
ATTENTION: This full spectrum LED lamp must NOT be operated with a dimmer!
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.
