Review: The Best Alarm Clock EVER. - Read this if you are NOT a morning person. Disclaimer: ahead is an unnecessarily lengthy and entirely over exaggerated description of a mediocre moment in my life. Enjoy! This week I decided I needed a change. I began my search for something refreshing to kick start my mornings. So, I bought a new alarm clock called the Wake Up Light. If you don't know what I'm talking about, prepare to be amazed, dear friend. It's an orb shaped apparatus that you set to the desired wake up time just like a regular alarm clock. However, unlike the traditional concept of inducing a mild heart attack with harsh blaring or ringing, this one will gently wake you by emitting light. This starts 30 minutes before you need to get out of bed and take charge of your life. At the beginning, it starts out as a soft red glow, and gradually increases over those 30 minutes into a bright white light. The idea is for this to simulate a sunrise. Pretty fancy, right? In the words of the great Billy Mays (may he Rest In Peace) "BUT WAIT THERE'S MORE!" This fantastically designed sphere of happiness gives you 5 peaceful alarm options to choose from as well. I chose the birds chirping, because who doesn't want to wake up feeling like Snow White surrounded by her fuzzy critter friends? I am 100% serious when I say that I felt just like that this morning. I wanted to go outside and dance in the puddles while wearing a dress made of rose petals hand stitched by fairies, meanwhile spinning around in circles and singing to all of the cute little forest dwellers. Side note: I don't actually live anywhere near the forest, but you get the point. Before this wonderful ball of light entered my life in an desertcart Prime box by the front door, I was absolutely appalled by my iPhone alarm sounding off every morning. Why? Well, I'm so glad you asked! Simply because every evening, I would beg my iPhone to wake me at 6:30 the following morning. I would open my clock app and politely slide the small grey buttons, revealing a green bubble that indicated my request had been processed and approved. However, despite my nightly requests, the iPhone failed me time after time. (I hate to break it to you Apple, but your alarms are ineffective and no match for a heavy sleeper like me.) Eventually, the amount of green lights illuminating from my cellular device became excessive and quite frankly, annoying. In order for me to wake up at 6:30, my alarms began going off at 5:00 and continued in 5-10 minute increments. I know what you're thinking, and yes, it was absolutely necessary to set that many alarms. Even so, my mornings usually began with my barely open eyes searching for the small rectangle of malevolence called "Audrey's iPhone". My sleepy eyes along with my sheet creased arms would move in unison on the bedside table to try and locate the device. My finger eagerly detected and pressed the side button demanding it cease production of the vile screeches overflowing into my bedroom and filling my ears. Once I had triumphantly silenced the alarms, I would squint at the clock with my tangled hair obstructing my already blurred vision. With hopes of seeing the screen display 6:30, I would be crushed by the reality that I had once again overslept. 7:00 would begin mocking me on the screen, as I fumbled through the dark reciting my traditional panicked morning chant, "Oh, no I'm going to be so late!" This every morning routine was beginning to have a negative impact on my poor husband as well. I am sure he was losing sleep because of this, even though he would never admit it. Not to mention, the funky intro to Brass Monkey on repeat can bring even the biggest Beastie Boys fan to the point of nearing a psychotic break, but I digress. Today was different. Even though I went to sleep at the ungodly hour of 2:00, this morning was an awakening accompanied by true peace and serenity. The light began its ascent to full illumination at 6:00. Although I did not stir at this point, I sat up fully awake at exactly 6:16. This glorious clock had not even fully completed the process of gently pulling me away from my dream, yet there I was, awake, baffled, and overwhelmed with joy. I attempted to fall back asleep and indulge in the remaining 14 minutes of sleep, but, alas, I could not. This clock had defeated me. Without a single shred of resentment toward my new favorite device, I left the comfort of my bed, and let the dogs outside with a smile on my face. I was ready to conquer this Friday, and I had my new alarm to thank for it. No longer are my days of sleeping past the time I should have already been on my way to work. No longer are my days of distaste for the iPhone. No longer are the days I wake up startled and confused. Thank you, Philips for your wonderful, life changing creation. If you are anything like me, please do yourself a favor and purchase one of these immediately. Seriously, you will (obviously) not regret it.
Review: The sunrise simulator really works! - I purchased this sunrise simulator alarm clock almost 5 and a half years ago (September 2016). I am happy to see it is still available on desertcart. The price doesn't appear to have changed much, but perhaps that's just because this thing is so great!! I use this every day. This gives you the option for two alarm settings, so I have one set for weekdays and another set for weekends. My wake-up sound of choice? Birds chirping. There are a few other serene sounds you can choose as well. About a half hour before your alarm is set to go off, the sunrise simulator starts up. It starts with a dull, deep red and gradually gets brighter, then goes orange and gradually gets brighter and more golden, then it starts going white the brighter it gets until your alarm goes off. When the alarm goes off, it starts off quiet and gradually gets louder. You can choose how loud you want the alarm to get. You have three options at this point. You can either press the alarm button to reset it for the next day, press the alarm button twice to shut off the alarm completely until you press it again to turn it back on, or you can tap the clock (or the table it's sitting on, which is what I do) for it to snooze for 9 minutes. It will snooze for up to an hour before resetting itself for the next day. You will have to turn the light off yourself regardless of which option you choose. I do wish the alarm didn't auto shut off after an hour though, but I think the reason behind it is in case you forget to hit the alarm button to reset it or shut it off. I've done this on occasion and came back into my room after a shower with the alarm going off, but it will shut itself off eventually. This is not a smart device, in that it doesn't connect to wifi or bluetooth. You will have to change the clock twice a year for daylight saving time. I don't usually use the radio, but I have bumped the button a few times to know it works. It does come with an attached antenna as well, which is just a thin rubber coated wire. I don't typically use the sunset/sleep setting to really have anything to say about it other than it works. One thing I like about the clock display is it auto brightens and auto dims according to the room's light setting. The clock is dull enough when the lights are out that it won't bother you if you're trying to sleep and the clock will brighten in sunlight or when the lights are on so you can see it better. Also, you're able to choose the clock to display a 24 hour clock or 12 hour clock (00:01 to 23:59 or 12:00-11:59am to 12:00-11:59pm). I also use this as a bedside lamp as well, if I've got the TV on or if I'm reading a book. I like that there are 20 brightness settings. It can also be used as a night light. One con is trying to navigate the buttons. It's tougher when the light is at full brightness because you can't see the buttons very well. There are three buttons together at the top left for brightness down, light on/off, and brightness up. There is a small brail-type dot on the on/off button but it's not noticeable enough not to accidently change the brightness when you're trying to turn it off. You more or less need to close your eyes and let your sense of touch figure it out for you. It's really not that big of a deal though, just a little annoying. The only time I've bumped the radio button or the sunset button is because I don't always use the second alarm and I'm trying to figure out which button is which. Overall, I love this thing! It really works, though nothing will ever be as good as actually waking up to the sun coming in. This is a particularly important tool to have if you suffer from Seasonal Affective Disorder (SAD) or have blackout curtains because you work midnight shifts, or maybe you're just not a morning person. Waking up to a nature sound is a nice touch too. I want to make note that some reviews have mentioned not being able to replace the light bulb or the light stops working in 2-3 years... again, I have had this for 5 years and 4 months now and I have never had the light stop working. It's still going strong. And I use this 5-7 days per week and have since I purchased it. The only things about it I wish were different are making the buttons easier to navigate when the light is bright (best way I can do this now is turning the brightness down before trying to discover the on/off button) and I wish the clock changed automatically in accordance to Daylight Saving Time. If anything does happen to this one, though, I will most definitely be purchasing another. Update January 2026: 7 months shy of 10 years... it died. I got up in the middle of the night to use the toilet, turned on the light on the sunrise simulator which I keep set low like a nightlight, took a few steps towards my bedroom door, and it turned off. No clock either. I had been noticing the past maybe 2 weeks that it had been making the clicking sound it makes when you press the menu buttons. I heard it maybe twice when I was in bed and they were lit up like they'd been touched. Perhaps that was my warning that it was about to go. I've come back here to purchase another - either an upgraded one or the same one. I don't really see any upgraded ones... and this one has increased in price by 50%!! Although I don't want anything but another of these, I will be looking at other brands and weigh my options. Breaks my heart to say that, actually.... but a replacement is a MUST.

## Questions & Answers

**Q: I need an alarm that makes no sound at all . Is there an option to turn off all sound?**
A: The Sonic Bomb has a pad that vibrates under your pillow. Since my wake-light only lasted 2 years, I got the Bomb, because I didn’t hear the alarm clock. I prefer the Wake-up light, but you can’t replace the bulb. I am not paying $100 every time the bulb dies in 2 to 3 years.

**Q: what are the 5 choices of sounds?**
A: Loud bird chirping, (rainforest maybe?) birds screeching and calls, music with birds, piano music, and the distant sound of waves under seagulls

**Q: Is the light very blue from the LED?   I'm thinking of the blue-ish tinted "white" LED christmas lights...   I prefer the warmer colors!**
A: The LED light is not blue or white... It's a sort of orange color. Very warm and pleasant. You can also adjust the intensity of the LED light to make it very soft so you won't notice it in the dark. Perfect for people that prefer to sleep in a completely dark room, like me. But you can still see the time, even with the soft LED settings.

**Q: Is it worth the extra money to buy this over the HF3470?**
A: Hey BenjaminThere is a side-by-side comparison of the various lamps Philips makes at the end of the listing for the HF3470.  It looks like it boils down to this:  The HF3470 has a replaceable bulb (what that entails, I couldn't tell you.  It looks like the HF3520 must be a "forever" bulb).  The HF 3470 has a "sunrise simulation" which I dig, and helps me wake up more naturally, which is what I bought the product for in the first place, so that was important to me, but is it for you?  Lastly, the HF3470 has 2 sound simulations whereas the HF3520 has 5.  I wouldn't call that particular facet a deal breaker.  It looks to boil down to the idea of the sunrise simulation and is that worth roughly $60 for you?  Happy shopping.

### ⭐⭐⭐⭐ VS Philips Hue
*by J***N on April 2, 2014*

I do like the light. It does do what it says, but the one problem I have with it is that it is VERY directional. Sleeping on one side and its like headlights in your face. On the other side its pleasant (back facing the light) and wakes me up nicely. I would lower the brightness, but I dont think a low brightness would wake me if I werent facing it (and I roll around all during the night, I wake up on either side). Looking toward the clock made it tough for me to turn off because it was so bright. I was still only using brightness 14 of 20 and its plenty bright. So if you are worried about brightness, I would say, dont be. I got the product because of my extreme sensitivity to light. Turning on a light in the morning takes me a little while to adjust to (complete dark to bright light). I like this idea of this clock as it did help with my adjusting to light phase. It gave my eyes time to "wake up" even if me eyes were closed, its not pitch black and they are slowly adjusting. Im returning my order because my clock would not snooze the audio when I touched it. As I was going to replace the product, I came across the Hue lights also by Philips. They also have an alarm feature (9 minute fade in) and Im sure the light doesnt adjust as awesomely as this one does, but I am going to try those with a light on each side of the bed and see if that helps. Also, these are not really to be used as a light for a room, its very directional. If you dont have vision problems with sensitivity to light like me, this will probably be awesome. Ill update with how I like the philips hue as an alarm. Update: After a day of playing with the Hue, I really like it. There is a reason that the same company sells both items. The Hue cannot come close to the brightness levels of this alarm clock. The clock can get significantly brighter (but its more like a spotlight, the Hue lights up the room/scattered light) and the major thing is that the alarm can get extremely dim. The Hue lights will probably wake light sleepers up when they come on due to not being able to get as dim as the alarm clock. They do get pretty dim, but they come on all of a sudden. They just cannot match the great progression of dark to light of the alarm clock. Im personally going to try to put a dark shade on the hue light to dim it down some and have another light across the room come on a few minutes after the one by my bed. For now, Im keeping the Hue lights, and going to try to adjust them to wake me up...If I cannot I will rebuy one of these alarm clocks and have it come on like 10 minutes before the hue lights start lighting up the whole room.
