5 watts LED spot lamp Pure-Z-Retro by Biolicht | Bright as 40 watts | 380 Lumen. Warm white (2700 K). GU10 socket.


LED SPOT lamps in this quality class represent the state of the art in lighting technology and are highly recommended from a building biology point of view. Their light output corresponds to that of a 40 Watt light bulb. This Bio Light LED SPOT produces a friendly warm white light and is almost flicker-free. The measured value of the pulsating light is less than 1 percent.

This Pure-Z-Retro LED SPOT can be used in any lamp with GU10 socket.

Delivery time: approx. 1-3 working days | formerly energy class A+

Natural light spectrum! + CRI/Ra of >90! + maximum flicker reduced!

Feel-good LED SPOT lamp Pure-Z-Retro with GU10 socket. A natural BIO LIGHT with excellent colour rendition and almost “flicker-free”. Not dimmable.

The almost continuous spectrum of the emitted light is close to that of incandescent lamps or halogen lamps, but without the proportion of heat radiation (IR or infrared radiation).

Details make all 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 >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 is approx. 36° and can therefore be focused very precisely on the area of application.  LED lamps are made of a semiconductor and are operated with integrated ballast. The resulting voltage produces a “light flicker” (pulsation). This pulsation could be reduced to a minimum (below 1%) with the “Spot” LED.

Electrosmog: The Pure-Z-Retro LED SPOT has been designed to produce low technical fields comparable to those of a light bulb.

Consideration of the time of day: The light spectrum of this LED SPOT has a slightly higher blue component compared to incandescent 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.

Pay attention to healthy light when buying lamps!
Healthy light from a building biology point of view, is a light source with a

  • lowest flicker – as close as possible to 0 Hz (Hertz)
  • The light spectrum/colour spectrum should be as natural as possible, without the usual excessive blue light component of an LED, for example. This serves to protect the macula (prophylaxis against early macular degeneration).
  • Color temperature warm white, 2700 K (Kelvin) in living areas
  • Unfortunately, the classic light bulb was banned. Good alternatives are: the halogen lamp G9 or the handle to high-quality LED light.

    Ob die Lampe flackerfrei ist, kann ich beim hinschauen nicht erkennen aber das Licht ist sehr angenehmn und man spürt einen Unterschied zu herkömmlichen LED-Leuchten.
