How the Deluxe Light Therapy Lamp Works
PER3 emits the wavelength and intensity of light that has been proven to improve health and general well-being. The PER3 works to subtly reset your internal cycles, adjusting your body clock with its light therapy program.

The PER3's Natural Light Alarm Clock with a programmable dawn and dusk simulator uses proven technology to ease you into waking and sleep states. This subtle light therapy helps keep your spirits high and set you on a standard time zone or work schedule. The PER3 also serves as a glare-free bedside reading lamp; its clear bright light is highly beneficial for reading.

The PER3 boosts your exposure to light in the early morning hours, simulating the exposure you'd receive on a sunny summer morning.

Dawn and Dusk Simulation Therapy
With its naturalistic dawn simulation and bright light therapy, the PER3 mimics both the gradually increasing light of sunrise as well as the progressively fading light of sunset. Your body reacts to these gentle changes by recalibrating its internal clock, or circadian rhythms. This results in more balanced and restful sleep cycles, even in instances of night shift work or long distance travel.

It has been clinically proven that exposure to light in the early morning hours is most effective for treating SAD. The PER3's naturalistic dawn stimulation therapy has antidepressant properties. When you awake with a gentle dawn-simulation alarm clock, you are able to treat symptoms of SAD easily and effectively, without needing supplemental short sessions of bright light therapy later in the day.

A Host of Benefits
Useful for insomnia, fitful sleep, and difficulties waking in the morning, the PER3's naturalistic dawn simulation therapy has no negative side effects. This attractive lamp enables you to support the body's natural processes and combat the stress associated with modern and hectic 24/7 schedules. PER3's swivel arm and pivot head features allow you to easily adjust the direction of the LED light so you can receive your light treatment as soon as you wake up, bathing the face evenly in therapeutic light.

Other great benefits:

• Twice as effective at reversing SAD symptoms, thanks to naturalist dawn simulation therapy and bright light therapy
• Eliminates the 30 minutes necessary for conventional morning light therapy
• No UV rays; powered by solely non-invasive technology
• Long lasting (up to 100,000 hours)
• Energy efficient (consumes only 1/10 the power of incandescent lights)
• As portable and versatile as an alarm clock or reading lamp

Clinical Study Conclusions
Case studies using a combination of dawn and dusk signals are very promising. These signals can help produce smoother sleep onset. Researchers at Columbia University Medical School conclude: "Twilight exposure appears able to promote circadian phase adjustments, morning melatonin suppression, regularized sleep patterns, and antidepressant responses."

Accolades for PER3's Delux Light Therapy Lamp
PER3 has been singled out by doctors at the Massachusetts General Hospital in Boston as being "best of breed" when recommending light therapy to their patients with SAD.

Customer Reviews

Not a Dawn Simulator or Light Therapy Device
I am an academic psychiatrist, and have reviewed the scientific articles on Dawn Simulation and Light Therapy, both of which are promising treatments for Seasonal Affective Disorder and also helpful for people who need to get up before the sun. I recently purchased this device and will be returning it today. As another reviewer described, when set for "Dawn Simulation" it starts at 10% for 29min then increases to 100% in the last minute. Real dawn simulators start with a nearly imperceptable amount of light and increase gradually to a modest (300lux)amount of light at awakening time with a goal of broad illumination of the sleeping area. This lamp is very directional and would not provide even illumination of a pillow from a bedside table. The traditional intensity for Light Therapy is 10,000 lux. This lamp does not reveal its intensity, but it is much less bright than a real 10,000 lux light I have. It would likely require much longer exposure times for the same effect. Their online literature references the importance of blue wavelengths, which appears to be true, but does not reveal output in that range. The clock display is not visible unless the lamp is on.

In summary, It is NOT a dawn simulator, and NOT a Light Therapy Device.
It is a poor desk lamp and a miserable clock.

Great features, some problems
I bought the lamp a couple weeks ago as it was the only one listed that has both a dawn simulator and light therapy function. I came pretty close to returning it due to a few issues with the unit (and I had found another product online - Morning Sunrise SRS320 - that has both dawn simulator and light therapy features). First of all, it looks ugly and feels flimsy - lightweight plastic, garish LED lights, and buttons that beep each time you press them. I can accept that; the lamp is significantly cheaper than most of the single-purpose light therapy boxes, none of which are especially beautiful either.
The most frustrating flaw was the difficulty of setting up and testing the sunrise feature; the first morning the "sun" rose quite a bit earlier than I thought I had set it for. Attempts at testing the feature by setting the wake time for 32 minutes in the future and the sunrise time for 30 minutes did not result in dawn glimmerings in two minutes. I'm not sure if this was a problem with the clock or with the directions...I subsequently seem to have gotten it working, but you should be aware than a 30-minute dawn consists of 29 minutes of light at 10% brightness (which is still rather harsh first thing in the morning) and then a 1-minute ramp up to 100% brightness. The clock does not allow a sunrise of less than 30 minutes. The sunset feature does seem to ramp down more evenly from 100% to dark in the set time.

This works GREAT for me!
I identified myself as suffering from SAD over 15 years ago. After consultation with a psychopharmacologist and use of antidepressants for a period of time he suggested I try light therapy during the winter. That was the answer for me. I have used the large light boxes one must sit in front of for 30-60 minutes each morning for years but still wished it was easier to get up in the morning during the dark winter months. I bought this lamp solely for its dawn simulation aspect. It took me a few attempts to understand the directions for the dawn simulation but have been using it since October and it has been wonderful. I have it sitting in front of my east facing bedroom window about 5 feet from my bed with the light pointed directly at the bed-- not the typical lamp stance. It bathes my room with light gradually over a 30 minute period. As reaches its full intensity it has a gentle 'tweet' sound for the alarm. Several mornings I awoke thinking truly the sun was coming in the window -- but alas, no, it is still winter! It is easy to adjust the time of day the simulation occurs, or turn it off completely, as I like to sleep later than 6am on the weekends. I give this a 5 star rating. It is an EXCELLENT dawn simulator doing for me exactly what I had hoped it would. Take it from someone who has dealt with SAD for years and used a variety of products to help alleviate the symptoms.
