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. Symbol: LX. Also called meter-candle. Basically, it’s a unit of light measurement.
How much Lux do I need for light therapy?
Light Therapy Research Bright light treatment requires a minimum of 2,500 lux to be effective, and the brightness recommended by researchers and clinicians for most people is 10,000 lux – an amount significantly higher than standard indoor lighting.
Do light therapy lamps help with vitamin D?
Even though it’s a light-based therapy, sun lamps don’t impact vitamin D production. Be sure to get your vitamin D through your diet and/or supplements as your doctor advises.
How many lumens do I need for a SAD light?
SAD lamps require a very intense light source with a high color temperature to help mitigate the effects of seasonal depression. These lamps are rated for 5,000 to 10,000 lux (or 10,000 Lumens per square foot), with the majority of lamps favoring 10,000 for good measure.
Is 10000 lux good for light therapy?
10K Lux is the recommended brightness for light therapy to be effective, but not all 10K Lux is the same. The cheaper Happy Light Luxe, per the company itself, is 10K Lux at a distance of 5-6 inches, and drops off from there. Obviously, no one is sitting with their face within 5-6 inches of an SAD lamp.
What is the difference between lumens and lux?
The difference between lumen and lux is that the lux takes into account the area over which the luminous flux (lumens) is spread. A flux of 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 Lux.
Can you overdo light therapy?
What Are the Risks? Red light therapy is generally considered safe, even though researchers aren’t exactly sure how and why it works. And there are no set rules on how much light to use. Too much light may damage skin tissue, but too little might not work as well.
Do light therapy lamps cause skin damage?
People with light sensitivity, bipolar disorder, diabetes, or eye conditions should avoid having the treatment. Experts advise individuals who wish to try light therapy to use only SAD lamps that emit fluorescent light with no UV wavelengths, which can damage the skin and lead to skin cancer.
Is 10000 lux enough for SAD?
To treat SAD, a 10,000 lux light therapy box is recommended at a distance of between 16 and 24 inches from your face. This distance is important because therapeutic light needs to reach your eyes to be effective.
Is Lux a lumen?
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.
