What is the benefit of full-spectrum light?

First of all, it is safe for the eyes. The full-spectrum lighting of SVET allows you to see the colors of your surroundings with minimal distortions. This is very important for our vision and well-being, as natural colors are more comfortable for the eyes.

Would this have the same effect as a sun lamp used to aid in SAD (seasonal affective disorder)?

SVET helps to prevent SAD as it repeats natural dynamics of the light to improve your biological rhythm. It means, among other things, that you get more blue light in the morning to energize you for the rest of the day.

How does light affect sleep?

Blue light suppresses melatonin. Melatonin is a hormone naturally produced by the body at night when it is dark. It is necessary for a proper sleep, but it is also a powerful antioxidant and has many beneficial health effects. That means the more light we are exposed to as we get ready for bed, the harder it will be to fall asleep and get a good night’s rest. Any immediate shifts from bright light to darkness can also make it harder to fall asleep.

How can light help me wake up easier?

Waking up with first sunlight is not just due to irritation from light rays. We perceive light through closed eyes in our sleep, and the specific properties of dawn light serve as triggers for the body to prepare us for wake up. While we are still sleeping, the nervous system wakes up internal organs and increases brain activity by degrees. The final moments up to waking up occurs when the whole body is prepared and is completely stressless with the right lighting.

Is it similar to 'wake-up' lights available on the market?

SVET is a dynamic lighting solution – it’s not just for wakeups. SVET is designed to support you during the day when you are at home or in the office. Based on your biological rhythm, SVET helps you to be alert in the first part of the day and relaxed in the evening if you need it. All lighting scenarios change dynamically based on your individual preferences.

Does SVET work with a sleep cycle app?

No. There is no need for such an app if you are planning to wake up with light. Waking up with light is very different compared to the usual alarm clock wakeups. Read our blog post about it here: http://blog.svet.io/post/128705031309/stressless-wakeups-with-natural-lighting

How does light influence my productivity?

A number of studies have shown that exposure to blue-heavy lighting promotes alertness, increases energy and enhances overall performance. Basically, a light with an increased blue light spectrum helps concentrate better, which is a desirable effect for a work environment. At the same time, a light completely devoid of blue, or at least with a much lower amount of it, may be used to achieve better results when we do not need alertness and increased energy. Having the ability to tune lighting at will gives you more control over your productivity and recreation.

Is it possible to boost productivity with light?

Yes, we achieve better results and make fewer mistakes when the lighting environment is suitable for our activity. Different setups of lighting can be used to stimulate concentration, provide a relaxing atmosphere, and otherwise affect performance or mental state.

What are the detailed SVET specs?

They are as follows:

Output range: 1000 lumen

CRI: 90-96 (for CCT from 1800K to 8000K)

CCT range (white): 1800K-8000K

Wattage: 13W

Power Factor: 0.9

Voltage: 100-240V/50-60Hz

Lifespan: 30,000 hours (5+ years)

Flicker Index: <1% (at brightness >60%)

Fits with Edison E26/E27 sockets and bayonet type B22

If LEDs do not have flicker, where does this flicker come from?

LEDs themselves do not have flicker. But LED light bulbs can have flicker because they use LED drivers, which convert AC to DC. SVET uses analog dimming to avoid flickering when changing the brightness.

Does SVET keep luminosity the same if you change the color temperature?

Luminosity decreases about 10% at low color temperatures like 2000K.

Is SVET suitable for outdoor use?

No. SVET light bulbs have not been designed for outdoor use. Using SVET light bulbs outdoors may void the warranty.

Can SVET light bulbs be used outside the US?

Yes. SVET light bulbs have a universal power supply – 100-240V/50-60Hz

Can I use SVET light bulbs with a dimmer?

Most dimmers are not designed to operate with LED light bulbs. SVET is a LED light bulb and requires 100% power to operate. Please use the SVET app to dim the light.

How does SVET help save energy and ecology?

SVET LED bulbs use significantly less energy than incandescent light bulbs. They do not contain mercury or lead, and can be recycled in the same way as any other electronic device. No precautions are needed if they break. SVET lighting saves up to 90% more energy compared to traditional lighting sources.

What about 2b radiation and the EMF (the electric and magnetic fields)?

LED light bulbs use 10 times less power than usual light bulbs, which means 10 times less electrical and magnetic waves. SVET light bulbs use ZigBee and Bluetooth LE (all low-power) wireless protocols. These radio frequency transmissions operate at minuscule power levels even compared to WiFi and Cell phones. On top of that, most of the time the transmitters remain in “sleep mode” – listening, but not transmitting (and thus not emitting any danger radiation).

What's the difference between SVET and other similar lighting solutions?

The main difference is in the quality of light and its dynamics. SVET light bulbs have rich spectrum, which mimics daylight dynamics during the day based on your wake-up and bed time automatically. Additionally, SVET is flicker-free, which is comfortable for the eyes, and has a high CRI of 90-96. The most important unique feature of SVET is the biological safety. It ensures that the lighting chosen manually will not harm your biological rhythm.

Can you change the light color of SVET light bulbs?

Yes, SVET light bulbs are able to change light color, from deep red to deep blue.

Is SVET good for a reef aquarium?

SVET is not designed to be used in reef aquariums. Reef aquarium lighting requires UV part of the spectrum, which is not safe to use in residential lighting.

Is it good for parrots / exotic birds?

SVET light bulbs do not emit UV or IR part of the spectrum. So, it is safe for them but exotic birds need the UV part of the spectrum.
