Product detailed description
Improve your sleep with a safe red light bulb that is free from blue light.
Our new, practical indoor bulb with warm red light is designed to improve your sleep and ensure it remains uninterrupted. The bulb fits a standard E27 screw fitting, is energy saving (7 W), and is perfect for every household. It is ideal for use mainly in the evenings in bedrooms, rooms, hallways, and is suitable for both adults and babies. The bulb is a great alternative to our smaller - E14 bulb.
The bulb is free from blue and green light and practically flicker-free (measured flicker index 0.01). Its warm red light sends a 270× weaker signal to the body clock than an ordinary white LED at the same lux, so it practically does not hold back evening melatonin.
✅ Warm red light without the blue part.
✅ Energy saving.
✅ Blue light free and flicker-free.
✅ E27 screw fitting.
✅ Wake up feeling refreshed and full of energy for the day ahead.
Why this product
Key features: Evening red bulb Mitochondriak® E27
6 key features based on the product's verified parameters.

E27 socket
Standard E27 socket fits any regular fixture.
Sends a 270× weaker signal to the body clock than an ordinary white LED at the same lux (measured, CIE S 026).
Energy-efficient
Only 7 W power draw for full-quality light.
Long lifespan
A lifespan of 25,000–50,000 hours.
Red bulb E27 under the spectrometer: Mitochondriak Lab measurement
We don't guess, we measure. We measured the bulb in a dark room with two certified spectrometers at 50 cm. The E27 is the deepest red of our bulbs: the spectral peak sits at 656 nm and 95 % of its energy lies above 620 nm.
- Blue light below 500 nm: practically 0 %
- Signal to the body clock: 270× weaker than an ordinary white LED at the same lux
- Melanopic EDI at 50 cm: 0.2 lx (the experts' evening ceiling is 10 lx)
- Flicker: flicker-free, flicker index 0.01
Why does a lux meter show less than with the E14? Lux weights light by the eye's sensitivity to green, so it undervalues deep red. The radiant power at 50 cm is similar, 1.5 W/m².
Technical data: E27 base, 7 W, luminous flux approx. 250–350 lm, AC 110–240 V, not dimmable, lifespan 25,000–50,000 hours. All parameters are listed in the Specification tab.

MITOCHONDRIAK® RED LIGHT BULB E27 = ZERO BLUE LIGHT and ZERO FLICKER
Let's STOP artificial blue light, especially in the evening!
While exposure to natural daylight helps regulate (and reset) our circadian rhythm and supports wakefulness, darkness and the absence of blue light in the evening signal our body to start producing melatonin, the hormone that regulates sleep.
This is why it is important to pay attention to our lighting not only during the day, but also in the evening (or at night, in case you need to get up).
Being practically flicker-free, our E27 red light bulb provides a great and calming evening light, ideal for use at home after sunset.
HOW TO USE OUR MITOCHONDRIAK® RED EVENING BULB:
Simply insert the bulb into your table lamp with the E27 screw, ideally with a shade to prevent the light from shining directly into your eyes, and then just enjoy the cozy evening atmosphere.
- Use the bulb in the last 2–3 hours before sleep instead of common cold white LED bulbs that emit blue light.
You can combine it with blue light blocking glasses, or the Mitochondriak® red night light with motion sensor to create the perfect atmosphere at home and experience high-quality sleep.

WHY SHOULD WE BLOCK BLUE LIGHT?
Do you often watch TV late into the night or work at your computer? Evening blue light from screens may go hand in hand with tired eyes and sleep that feels worse. You cannot avoid it completely, but you can limit it in the evening, for example with blue light blocking glasses, which reduce the amount of blue light reaching your eyes in the evening and support your natural evening melatonin rhythm and circadian rhythm.
If you are interested in reducing the negative effects of artificial blue light in your household, try the Mitochondriak ® indoor lightning solutions. Your home atmosphere can also be improved with Mitochondriak® red light therapy devices which use red and infrared light.

How returns work
Frequently asked questions: Evening red bulb Mitochondriak® E27
Is the product free of flicker and EMF?
Yes. We measured flicker: flicker index 0.01 and fluctuation below 5 %, so it is practically flicker-free. At 7 W the EMF is low and the bulb meets CE and RoHS standards.
What socket type does this bulb use?
This bulb uses a standard E27 socket, so it fits easily into any regular fixture.
Does this bulb support my circadian rhythm?
Yes. Its warm red light sends a 270× weaker signal to the body clock than an ordinary white LED at the same lux, so it practically does not hold back evening melatonin production.
Is this bulb energy-efficient?
Yes, the bulb only draws 7 W, making it very energy-efficient.
