How many Lux is dangerous?
Indirect sunlight is 10,000 to 25,000 lux, which is safe.
So basically, don’t look directly at any light that is more than 25,000 lux and you should be safe..
Do SAD lights help vitamin D deficiency?
Seasonal Affective Disorder (SAD) light box therapy is not effective for treating vitamin D deficiency. SAD lamps use an entirely different physiological process that uses the visible light spectrum to stimulate the retina in a way that has an effect on circadian rhythm.
How many Lux is too bright?
More than 500 lux – If you have an area where intricate work is being carried out, then very high lux values may be needed. Where fine detailed work is being carried out, anything up to 2,000 lux can be used – this is usually only necessary in fairly unusual circumstances.
Does light therapy help anxiety?
Anxiety and depression scores were significantly reduced following the light therapy at T3 in both the high- and low-intensity groups. Conclusions: Light therapy resulted in a significant reduction in symptoms of anxiety and depression but we did not find any differences between high- v. low-intensity treatment.
Which verilux light is best?
Optimal light intensity. Research has found that anywhere between 2,500 and 10,000 lux is the ideal light intensity. Our light therapy lamps deliver up to 10,000 lux of natural light while making light therapy convenient and comfortable – even for those always on the go or sensitive to light.
Do SAD lamps give you a tan?
Sun lamps used for SAD filter out most or all ultraviolet (UV) light. Using the wrong type of lamp could damage your eyes and cause other side effects. The type of sun lamps used to treat SAD will not give you a tan or increase your vitamin D levels.
How long should you sit in front of a sad light?
Light therapy is usually prescribed for 30 minutes to 2 hours a day, depending on the intensity of the light used and on whether you are starting out or have been using it for a while. Most light therapy is prescribed at 10,000 lux to be used in the early morning.
What is a 10000 Lux light?
10,000 Lux Always A unit of illumination, equivalent to 0.0929 foot-candle and equal to the illumination produced by luminous flux of one lumen falling perpendicularly on a surface one meter square. … Also called meter-candle. Basically, it’s a unit of light measurement.
What is Lux in LED light?
Lux is used to measure the amount of light output in a given area – one lux is equal to one lumen per square meter. It enables us to measure the total “amount” of visible light present and the intensity of the illumination on a surface. Thus, it is important in what direction the light source shines.
How do you use 10 000 lux light?
For SAD, the typical recommendation is to use a 10,000-lux light box at a distance of about 16 to 24 inches (41 to 61 centimeters) from your face. Duration. With a 10,000-lux light box, light therapy typically involves daily sessions of about 20 to 30 minutes.

What color light is good for depression?
Research indicates that blue light is superior to other lights in the spectrum for treating depression. Studies show that blue light can be used at a specific wavelength and frequency at less intensity than full spectrum bright light to achieve the same kind of effects.
How many lumens are in a Lux?
Lumens: The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter (lux = lumens/m2).
Is 10000 Lux a lot?
Lux is the measurement unit for illuminance and is equal to one lumen per square metre. It is usually recommended equipment with 10,000 lux is the most effective light therapy. While other equipment might be less, you would need more frequent and longer applications and they may not be as effective.
Can you convert Lux to lumens?
The fundamental ratio of conversion from desired lux level to required lumens is: 1 lux = 1 lumen per square meter. This is equivalent to: 1 lux = 0.0929 lumens per square foot.
How many Lux is a 100 watt light bulb?
1600 lumensTo replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
What does 1 lux look like?
A measurement of 1 lux is equal to the illumination of a one metre square surface that is one metre away from a single candle.

How bright should a sad light be?
Brighter boxes will require less time to use each day, compared with dimmer boxes, to achieve the same effect. Typically the recommended intensity of light is 10,000 lux. How much UV light does it release? Light boxes for SAD should be designed to filter out most or all UV light.
