Selecting the Right Light Therapy Lamp

What Should I Look for in a Light Therapy Box?

Looking for a therapy lamp? Our buyer's guide breaks down the necessities when considering your purchase.


Choosing a light therapy box can be confusing if you're new to phototherapy light treatment. You have many choices when selecting a natural light lamp, so it's essential to know key specifications, features, and terms before doing so. Our light therapy lamp buying guide will walk you through the essentials of selecting a light therapy light. This includes what they are, how they work, how to choose a light therapy lamp, compare our lamps, and showcase each model.

What is a Light Therapy Lamp?

A bright light therapy lamp (also called a sunlight light, wellbeing lamp, light box therapy lamp, and more) is a specially designed light made to mimic sunlight.

These lights help replenish sunlight exposure. They are often used to treat light-related conditions such as:

  • Seasonal affective disorder (seasonal depression),
  •  Insomnia
  • Jet lag 
  • And more.

How Does Phototherapy Work?

Light therapy is quite simple. It involves sitting in front of a light that mimics daylight each morning for 20 to 30 minutes. This tricks our body into producing two essential hormones: serotonin and melatonin.

Serotonin (which converts to melatonin) regulates mood, appetite, energy, sexual desire, and memory. Melatonin is vital to our sleep-wake cycle, known as our circadian rhythm.

By replenishing our access to sunlight via a sun lamp, we're able to regulate our hormone levels to have more energy, sleep better, and combat light-related health conditions.

How Does Phototherapy work?
Light Therapy Lamps vs. Regular Lamps: Light therapy lamps are 10,000 LUX - Indoor lighting is 200-500 LUX at home and 400 to 700 LUX at offices

Light therapy Lamps vs. REgular Lamps

A common misconception about bright light therapy is that regular lamps can be used to get the benefits. While yes, it does help your sleep-wake cycle to have adequate lighting in your home, you won't get all the benefits of a therapy lamp from a standard light. The proper therapy lamp produces 10000 LUX, and some have five to twenty times more LUX than standard lamps.

Why Use a Light Box?

It's been found that Americans spend 90% of their time indoors and away from sunlight. This means we don't get all the benefits of the sun to lead a healthy life. And during colder months, getting outside can be challenging.

These specialized lights are an excellent alternative to sunlight. They can treat various mental health conditions, including seasonal depression, anxiety, and insomnia. They can also be used for those who want to enhance their physical, mental, and emotional wellbeing. And because they're relatively safe, you don't have to worry about any harmful side effects.

  • Light therapy lamps are specialized lights designed to mimic sunlight.
  • They're used to replenish sun exposure and used to treat seasonal depression, insomnia, jet lag, and more.
  • They differ from standard lamps as they emit 5-20 times more LUX (light intensity).
  • They're used each morning for 20-30 minutes to trick the body into producing serotonin and melatonin.
  • They can help improve energy levels, enhance sleep quality, and relieve poor mental health.

How to Choose a Light Box

Before selecting a therapy lamp, it's essential to know what to look for when buying a light therapy lamp. There are many available options in which many do not meet the requirements to produce the benefits of light therapy effectively. This section will guide you through what to look for in a SAD lamp.

Medical vs. Wellness Grade Therapy Lamps - Medical Grade: Ideal for those with severe conditions, 10,000 LUX from 12

Your Condition

For those diagnosed with a health condition such as seasonal affective disorder, it's vital to get a clinical/medical rated SAD light therapy lamp. These lights are designed to give out the max amount of light for optimal results. If you only have minor issues, a health/wellness rated lamp will work as well. Consult your doctor if you have any questions/concerns.

  • Medical grade SAD lamps: These types of sun therapy lamps typically are larger, direct light downward from an upward position, and produce 10,000 LUX from 12" away.
  • Health/Wellness grade lights: These are made to treat milder conditions and are typically smaller, making them ideal for compact spaces. They may produce 10,000 LUX, but this is usually from 10", which may require sitting in front of them for longer than 30 minutes each morning.
Size - Consider a lamp's dimensions to fit in your surroundings

Where are You Putting Your Lamp?

Each of our lamps offers different dimensions and sizes for different areas. If the location you'll be putting your lamp in is compact, then you should consider one of our smaller models.

Smaller sun lamps for office use can help with more severe cases of seasonal depression. However, they will need to be sat in front of for more extended periods.

Lifestyle - If you travel often, a smaller lamp may be ideal.

Your Lifestyle

If you travel a lot, you'll need a portable light box for SAD. These are compact, which makes them easy to use anywhere and pack in luggage. If you struggle with jet lag often, then a smaller therapy lamp might be a must-have. They can help combat the adverse side effects of traveling to varying time zones.

Light angle

Light Angle

If you are placing your therapy lamp in a crowded space, you'll want a lamp that offers flexibility with an adjustable angle. This will give you the option to adjust accordingly to your area. If you're looking for a medical-grade light therapy lamp, it should point light down from an upward angle. This allows light to reach the top of your eyes, just like the sun does.

Light sensitivity

Light Sensitivity

If you are sensitive to light, you might want to consider one of our models that feature different light brightness settings. Some may struggle with a light that can only be on/off without customizing the light intensity.

Lamps with adjustable intensity also double as a standard desk lamp. You can use them for light therapy sessions and then turn them down as a task lamp.

10,000 LUX


Not to be confused with a lumen (which measures how much light a device emits), LUX is the amount of light a device produces on a given surface. For optimal treatment, it's essential to have a 10 000 LUX light therapy lamp. Anything less may require longer treatments and not provide the same effectiveness.

Color temperature - Warmer colors promote comfort and cooler colors promote alterness

Color Temperature

A critical area often considered when selecting a SAD lamp is blue or white color. The color temperature of light refers to its "warmth" or "coolness." This is measured in kelvin (K).

Warmer lights, around 1,000 K, promote comfort and have a calming effect. Cooler lights, around 10,000 K, promote alertness. White lights, on the other hand, are in the 5,000 to 7,000 K range. These promote alertness but are easier on the eyes. You'll notice most offices use lights in this color temperature range.

Light spectrum - Full spectrum light: 380-730 nm, safer, less effective - Blue spectrum light: 380-500 nm, can be harmful to eyes, more effective

Light Spectrum

A significant aspect to consider is the light spectrum a lamp uses. Therapy lamps typically produce blue or full-spectrum light therapy.

While blue light has been proven to be more effective than full-spectrum lamps in treating SAD and low energy levels, it can be harmful to the eyes. This is especially true if the user is on any medications. Full-spectrum light boxes use traces of blue light but are much safer to use.

Ultraviolet (UV) Light Protection

Ultraviolet (UV) Light Protection

Many types of light produce ultraviolet light (UV). UV light is an invisible type of light that sits between visible light and X-ray on the electromagnetic spectrum.

While UV light has many uses, extensive exposure can cause skin damage. Because of this, it's vital to select a UV-free light therapy lamp. The proper 10000 LUX light will feature a built-in filter that keeps UV from reaching the user.

LED or Fluorescent? LED is safer, energy efficient, durable, and longer lasting

LED or Fluorescent

Older 10000 LUX energy light lamps tend to use fluorescent bulbs. They have since then been replaced with LED (light-emitting diode) bulbs. LEDs are notoriously safer, more energy-efficient & durable, and last much longer compared to fluorescent bulbs.

If you're considering purchasing an older used model that uses fluorescent bulbs, it's important to note that they will need to be replaced much quicker than LED models.

Extra freatures - Wireless phone charger, USB port, alarm clock

Additional Features

There are many SAD light specifications to consider from. One area you might be interested in is additional features. Newer lamps may feature extra features such as a:

  • Wireless phone charger
  • USB port
  • Alarm clock
  • And more.

These features can further enhance the user experience.

Product warranty with a 90-day return policy

Brand Return Policy & Warranty

As with any product, purchasing from a trusted brand is important. Any trustworthy brand will have a return policy and warranty in place for its customers. And because light therapy can be a critical tool for getting through winter, it's especially important to make sure you purchase through a brand with a return policy and warranty that protects your purchase. Consider these questions:

  • What happens if I end up not liking the product, can I return it?
  • What is the length of the return policy?
  • What does the return process look like? Is it convenient?
  • What happens if the product breaks? Is there a warranty in place?
  • How long is the warranty and what's covered under it?

Our Day-Light lamps come with a five-year warranty and our TheraLite lamps come with a one-year warranty. Each warranty covers the lamp under normal use should it malfunction or break.

Additionally, we offer a 90-day return policy. If our lamps don't live up to your expectations or you realize you have no use for them, you can return it within 90-days of purchase.

  • Before purchasing a lamp, it's important to consider a few factors.
  • If you've been diagnosed with seasonal depression, it's important to choose a medical-grade lamp. These are larger in size.
  • If your condition is mild to moderate, a smaller wellness grade lamp will suffice.
  • Your living space will also dictate your decision. Smaller spaces may require a smaller lamp.
  • If you travel often, you'll need a portable lamp.
  • A lamp with a flexible angle is ideal to direct the light toward your eyes.
  • If you are sensitive to light, a lamp with adjustable brightness may be ideal.
  • Be sure to check the light's LUX output. 10,000 LUX is the ideal output. Anything lower may require longer treatments.
  • Color temperature will dictate the effect of the lamp. Warmer lights, around 1,000 K, promote comfort and have a calming effect. Cooler lights, around 10,000 K, promote alertness. 
  • Most lamps emit either blue or full-spectrum light. Blue light is more effective but can be harmful to the eyes. Full-spectrum light uses traces of blue and is much safer.
  • A lamp with a UV filter is vital. UV exposure can cause skin damage.
  • Avoid lamps using fluorescent bulbs. LEDs last longer, are safer, last longer, and are energy efficient. 
  • Some lamps come with additional perks such as a wireless phone charger, alarm clock, USB port, and more.
  • Warranty and return policies are another key component to look for.
