Switchable 9 watt feel-good LED TRICOLOR Pure-Z-Retro with E27 base. Three switchable light colors (warm white, daylight white, cool white) produce an almost flicker-free natural BIO LIGHT with high color rendering. Not dimmable.
This LED is a 3-in-1 illuminant with a near-natural BIO light i.e. with a high color rendering and almost “flicker-free” light.
The almost continuous spectrum of the emitted light is in the “warm white” mode close to that of incandescent or halogen lamps, but without the proportion of heat radiation (IR or infrared radiation). However, the two other operating modes “daylight white” and “cold white” make this LED technologically superior.
With this TRICOLOR LED, we are expanding our existing 12 watt (comparable to 100 watts) and also switchable full spectrum DUOLIGHT LED by a further model with lower luminous intensity. If we use the LED DUOLIGHT in commercial offices, the focus of this LED TRICOLOR is on private households.
3in1 » 3 light colors in one LED
This color temperature switching technology was previously reserved mainly for commercial use due to price reasons. With this new development with reduced power, it has been possible to achieve an attractive price level. The reasons for this are private use, which is significantly lower in relation to commercial use, and the luminous intensity can also be lower.
The function for switching the light temperature remains the same, only the sequence of the individual light temperatures is adapted to the private household.
- Warm white with a color temperature of 3,000 Kelvin
- Daylight white with a color temperature of 4,000 Kelvin
- Cold white with a color temperature of 6,500 Kelvin
The color change takes place directly at the light switch on the wall. If the light switch is operated within 3 seconds with Off/On, the LED TRICOLOR changes to the next color temperature. If the light remains off for longer than 3 seconds, it restarts at the first color temperature, warm white with 3,000 Kelvin – similar to the classic Edison light bulb or halogen light.
Details make the difference. This is especially true for LED’s!
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 CRI of 100, these LEDs have a very good CRI of over 90.
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) a high one. This LED TRICOLOR is able to display 3 colour temperatures. Warm white, cold white and daylight white.
The light exit angle of almost 360º is very well suited for all applications where incandescent lamps were previously used.
LED lamps are made of a semiconductor and operated with integrated ballast. The resulting voltage produces a “light flicker” (pulsation). This pulsation could be reduced to a minimum (below 1 %) with the “filament” LED.
Electrosmog: The Pure-Z-Retro LED has been designed to generate low technical fields comparable to those of a light bulb.
Consideration of the time of day: This is exactly where this TRICOLOR LED shows its full strength in private rooms. Daylight white and cold white contain a significantly higher blue component. This influences the human waking state and prevents the formation of melatonin, which is absolutely necessary for restful sleep. Later in the day, when reading in the evening, in the living room, at the bedside table or generally in the period before going to bed, switch the operating mode to warm white.

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.Details on the new EU energy label 2021
