3 watt LED filament Pure-Z Retro | bright as 30 watts, 300 lumens | CRI >90 | flicker-free | warm white | E14

3 watt LED filament Pure-Z NEO with E14 socket. A natural feel-good BIO LIGHT with an incredible CRI 97 color rendering and almost “flicker-free”. Not dimmable.

The almost continuous spectrum of the light emitted is close to that of incandescent or halogen lamps but without the proportion of heat radiation (IR or infrared radiation). In addition to the rating “recommended for residential medicine”, this LED lamp in the clear glass version has also received the rating “GOOD” from ÖKO-TEST after a performance test.

The Pure-Z Retro LED produces an even, sunlight-like feel-good light in which the flicker content has been reduced to a minimum of < 1%. This LED is quasi the opposite to our full spectrum daylight lamps, which focus on the building biologically healthy lighting during the day, for the darker times (fog, cloudy, …) and the sunlight-reduced months of the year. The Pure-Z Retro LED, on the other hand, provides high-quality warm-white light throughout the year and is therefore ideal for cosy evenings at home – a light that makes you feel good.

CRI 90. Small detail, big effect!

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 good CRI >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) 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-Retro 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.

LED Filament Pure-Z Retro bulb almost flicker-free!

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.
