Description
Bring the full spectrum of natural sunlight into every room of your home. The BioLight Bulb shifts from balanced daylight to warm amber across three built in modes so your indoor lighting finally works with your circadian rhythm instead of against it.
Engineered with a CRI of 99+ the BioLight renders colours, skin tones and food with the same richness and accuracy as natural light. Standard LEDs sit around CRI 70 to 80 which is why everything looks flat and washed out under them. You will notice the difference the moment you switch.
Three modes are built into a single bulb. Day mode (4000K) delivers full spectrum white light with balanced amounts of blue, green, yellow, orange and red for stable energy and focus. Mixed mode (2100K) reduces blue light significantly producing the warm glow of a classic incandescent for mornings and early evenings. Night mode (1800K) eliminates blue light entirely. Only amber and red wavelengths remain so your brain can wind down and produce melatonin naturally.
Switching is simple. Flick your existing light switch off and on to cycle through modes. No app. No remote. No WiFi. No Bluetooth. The bulb remembers your last setting after 10 seconds so it powers back on exactly where you left it.
Completely flicker free. Standard LEDs transfer alternating current directly into light producing a rapid invisible strobe that contributes to eye strain, headaches and nervous system fatigue. The BioLight uses advanced circuitry to eliminate flicker entirely. Low EMF output with no wireless signals of any kind for a cleaner lighting environment.
Fits any standard E27 screw base lamp or ceiling fixture. (AC 110 to 265V) for worldwide use. Non dimmable. Use with a standard on/off switch only. If installed on a dimmer circuit keep the dimmer at maximum and do not adjust.
Rated for approximately 30 000 hours. That is over 10 years at 3 hours of use per day. Certified CE.
Routine & Ritual
The BioLight Bulb works best when it follows the rhythm of your day. No timers to set. No protocols to memorise. Just switch to the right mode at the right time and let the light do what it was designed to do.
Morning Activation
Start your day under Day mode. Turn the bulb on in the kitchen or bathroom while you get ready. Full spectrum 4000K light signals to your brain that the day has begun. Cortisol rises on schedule. Energy stabilises. Focus sharpens. Even 20 to 30 minutes of exposure during your morning routine helps anchor your circadian clock for the rest of the day.
Daytime Focus
Keep Day mode running in your workspace or home office. Balanced full spectrum light reduces the eye strain and headaches that come from spending hours under conventional blue heavy LEDs. Colours render accurately. Skin and surroundings look warm and natural. You stay alert without the overstimulation that standard lighting creates.
Late Afternoon Transition
As the afternoon settles switch to Mixed mode. The 2100K warm glow replicates the light of late afternoon sun. Blue light drops significantly. Your nervous system begins to ease without you noticing. This is the ideal setting for cooking, dining, reading or any activity where you want to feel present and relaxed without being drowsy.
Evening Wind Down
After sunset switch to Night mode. 1800K amber light with zero blue wavelengths. This is the signal your body needs to begin producing melatonin. Use it in the living room while you decompress or in the bedroom as you prepare for sleep. The warm amber glow feels like candlelight. Soft enough to relax under. Bright enough to see by.
Sleep Preparation
Leave Night mode on as a bedside light for reading or quiet time before sleep. Zero blue means zero interference with your natural sleep chemistry. When you are ready to sleep turn the bulb off. It remembers Night mode so it powers back on in the same setting if you need it during the night.
Tips for Best Results
Replace the bulbs in the rooms you use most. The more of your indoor environment that runs on full spectrum light the greater the cumulative benefit. Kitchen, living room and bedroom are the highest impact starting points.
Match the mode to the time of day. Day mode before mid afternoon. Mixed mode from late afternoon. Night mode after sunset. Your body adjusts quickly when the signals are consistent.
Consistency matters more than perfection. Even switching to Night mode after dinner and nothing else will improve your sleep quality within the first week. Build from there.
Pair with the Terrā Grounding Sheet at night for a sleep environment that supports recovery from both directions. Light and earth working together.

Hour Lifespan
The light you live under shapes how you feel. Most people spend ninety percent of their time indoors under lighting that works against their biology. The BioLight Bulb is the simple correction.
The Problem
Standard LEDs
- Excess blue light disrupts hormones and sleep. Damages eye health over time.
- Invisible flicker from low quality circuitry strains the nervous system and contributes to fatigue.
- Poor colour rendering makes skin and food appear flat, dull and lifeless.
- Smart bulbs rely on Bluetooth or WiFi which adds EMF exposure throughout the home.
- Fixed colour temperature ignores the body's circadian needs from morning to night.
The Solution
BioLight Bulb
- Full spectrum output replicates balanced natural sunlight across every visible wavelength.
- Completely flicker free. Advanced circuitry eliminates the invisible strobe of standard LEDs.
- CRI 99+ renders skin, food and surroundings in vivid true to life colour.
- Low EMF. No WiFi. No Bluetooth. No app. Just your existing light switch.
- Three modes shift from full spectrum day to zero blue amber for night.

Why Full Spectrum
The light you live under shapes how you feel
Natural sunlight contains a balanced spectrum of all visible wavelengths. It is the light humans evolved under for millions of years. Standard LEDs emit a narrow spike of blue light with very little red or amber. This imbalance contributes to eye strain, headaches, poor sleep and elevated stress.
The BioLight Bulb replicates the full visible spectrum of the sun. In day mode it delivers balanced white light your body needs for energy and focus. In evening mode it produces a warm amber glow free of blue wavelengths so your brain can wind down and produce melatonin naturally.
Spectrum Comparison

Frequently Asked Questions
You ask. We answer.
Standard LEDs emit a narrow spectrum dominated by blue light with very little red or amber. The BioLight Bulb produces balanced full spectrum light across all visible wavelengths to closely replicate natural sunlight. It also offers three switchable modes that move from energising daylight to warm amber with zero blue light for evening use. Completely flicker free and low EMF.
Use your existing light switch. Turn the bulb off and then on again quickly to cycle through the three modes: Day, Mixed and Night. When the bulb stays off for more than 10 seconds it remembers the last mode you used. No app, remote or dimmer is needed.
The BioLight Bulb uses a standard E27 screw base which is the most common residential fitting in South Africa, Europe, the UK and Australia. A B22 bayonet version is also available. It works with universal voltage (AC 110 to 265V) so it functions worldwide.
The BioLight Bulb is non dimmable and should be used with a standard on/off switch only. If your fixture is on a dimmer circuit keep the dimmer set to maximum and do not adjust it. The three built in modes provide all the brightness variation you need.
Cheap red or amber bulbs typically use a painted coating or narrow band LED that produces a very limited spectrum. Colour rendering is poor and the light quality is uncomfortable for everyday use. They also lack any full spectrum daytime mode so you would need separate bulbs for day and night. The BioLight gives you three optimised modes in a single bulb with CRI 99+ across the board.
The BioLight Bulb is rated for approximately 30 000 hours. At around 3 hours of use per day that translates to over 10 years of service.
The BioLight Bulb carries CE, FCC, ROHS, UKCA and RCM certifications. It is designed for indoor use only and meets international electrical safety standards.
