4 Watt LED Filament Pure-Z NEO | Bright as 38 watts, 400 lumens | CRI 97 | flicker-free | warm white | E14

4 Watt LED Filament Pure-Z NEO with E14 Socket. A Natural Feel-Good BIO LIGHT with a Very High Color Rendering of CRI 97 and Nearly Flicker-Free. Not Dimmable.

The nearly continuous spectrum of the emitted light is close to that of incandescent or halogen lamps but without the heat radiation component (IR or infrared radiation). In addition to the designation “recommended for residential wellness,” this LED bulb in the clear glass 6,4-watt variant received a “GOOD” rating from ÖKO-TEST following a performance test.

The Pure-Z NEO LED produces a consistent, sunlight-like feel-good light, with the flicker component reduced to a minimum of <1%. This LED serves as a counterpart to our full-spectrum daylight lamps, which are designed for biologically beneficial lighting during the day, especially for gloomy weather (fog, clouds, etc.) and the sun-reduced months of the year. By contrast, the Pure-Z NEO LED is ideal year-round as a high-quality warm white light for cozy evenings at home—a true feel-good light.

In the world of LEDs, it’s the details that matter most!

he 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 97. 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: The Pure-Z-NEO LED was designed to generate small technical fields comparable to those of a light bulb.

Consideration of the time of day: The light spectrum of the “filament” has a slightly higher blue component compared to incandescent lamps or halogen lamps. According to medical experts, this influences the human waking state or sleep (melatonin formation). We therefore recommend using LEDs in “active areas” (desks, kitchens, corridor lighting, etc.), at reading places in the evenings, at bedside tables or in the period before going to bed, to continue using incandescent lamps or G9 halogen lamps.
