Best for Who?

For those who suffer from seasonal affective disorder, the Philips HF3520 Wake-Up Light is one of the best products on the market that will improve your day for an ideal way of staying happy throughout the season in colder climates. Serotonin is needed in the brain to release endorphins and create a natural, happy attitude. Without light, it’s difficult to remain happy and healthy during the colder months of the year.

How is it Supposed to Be Used?

As a product that is scientifically proven to work, it helps you to wake up naturally without the sun present outside due to a natural, amber light. To get a few minutes of extra sleep without rushing out of bed, a snooze feature makes it possible to gently touch the product for an extra nine minutes of sleep.

User Reviews

Over 550 reviews are available on Amazon.com from customers who have purchased the Philips HF3520/60 Wake-Up Light product for a 4.3 out of five-star rating. Some of the written pros and cons on the website include:


“I bought the Philips goLITE BLU Light Therapy Device a few years ago to see if it could help with the winter blues, and I was amazed at how well it works. It is like a concentrated shot of sunshine that wakes my body up in the morning and gets me ready for the day. I love it, and have learned to trust in these Philips light devices.”

“First off, as a dawn simulator, it appears to be top notch. It’s a pleasant way to wake up, and I really enjoy the sunset simulation for relaxing in bed before falling asleep.”


“The birds didn’t get the memo. So what this clock does for me is it deprives me of 30 minutes of sleep and requires me to keep my phone by the bed so I can set a snooze alarm after I turn this thing off.”

“Good, but not Philips’s best wake-up light.”
