Understanding Lux: The Key to Effective Light Therapy

Updated: Apr 3

What Is Lux?


Lux is the measurement unit for illuminance, representing the amount of light that falls on a surface per unit area. It’s crucial in the context of light therapy because it directly impacts the effectiveness of your light therapy lamp.

Why Does Lux Matter for Light Therapy?


The brightness of your HAPPŸLAMP is expressed in lux. Here’s why it matters:

  1. Mimicking Sunlight: Light therapy aims to mimic natural sunlight. For optimal results, you’ll want a lamp that produces 10,000 lux—the closest we can get to the sun’s intensity. This level of brightness triggers essential biological responses in our bodies.

  2. Body’s Response: Exposure to bright light at 10,000 lux stimulates the production of serotonin (the “feel-good” neurotransmitter) and melatonin (which regulates sleep-wake cycles). These hormonal shifts improve energy, mood and overall well-being.

Choosing The Right Lux Level

Different conditions require specific lux levels. Let’s focus on bright light therapy:

  • Purpose: Bright light therapy is commonly used to prevent Seasonal Affective Disorder (SAD) and combat depression during autumn and winter months.

Recommended Lux: To achieve the full 10,000 lux benefit, sit approximately 30-40 cms away from your HAPPŸLAMP (which emits pure white light). Spending 20-30 minutes in front of your HAPPŸLAMP daily can significantly enhance your mood and energy levels. 


Comparing Lux Levels

Here’s a quick comparison of lux levels for various lighting conditions:

  • Direct Sunlight: 100,000 to 130,000 lux

  • Daylight Noon: 100,000 lux

  • Full Moon: 1 lux

  • Street Lighting: 10 lux

  • Home Lighting: 30 to 300 lux

  • Office Desk Lighting: 100 to 1,000 lux

  • Surgery Lighting: 10,000 lux

  • Overcast Day: 1,000 lux

  • Typical Living Room: 100 lux

Remember, the right lux level ensures effective light therapy. Always use your HAPPŸLAMP at 10,000 lux at a distance of 30-40cm. Let the light guide you toward better mental health! 🌞


What Is The Difference Between Lux And Lumens?


Lux and lumens are both measurements related to light, but they measure different aspects of light.

  • Lumens: Lumens measure the total amount of visible light emitted by a light source in all directions. In simpler terms, lumens indicate the brightness of a light source as perceived by the human eye. For example, a higher lumen rating indicates a brighter light source, while a lower rating indicates a dimmer light source.

  • Lux: Lux, on the other hand, measures the amount of light that falls on a surface per unit area. It takes into account the area over which the light is spread, in addition to the brightness of the light source. In essence, lux tells us how bright the illumination is at a given point on a surface. For instance, a bright light source placed close to a surface will result in higher lux values compared to the same light source placed farther away.

To summarise:

  • Lumens measure the total light output of a source.

  • Lux measures the intensity of light per unit area at a specific point on a surface.

In simpler terms, lumens tell us how much light is produced, while lux tells us how bright the light is at a particular spot.
