Set Contains: 1 X HF3531/01 Review: Good product but how useful? - The product works very well however, no issues at all. Nice design and cool features. However I haven’t used it much since it takes a long time to switch on and off (which defeats the purpose of it if you don’t). I regret buying it personally as it costs quite a lot but I recommend it if you need a circadian alarm clock.

Reso. Non accettato dal venditore ### ⭐⭐⭐⭐⭐ Brilliant product! *by C***1 on 12 March 2023* I used to wake up abruptly every morning to the shrill alarm from my mobile phone, every alarm on there was loud and abrupt and this has been the case with other mobile phones too. I was looking at alarm clocks generally and then started reading reviews about wake up light alarms and how they actually prepare your body to wake up naturally through gradual low level light that simulates a sunrise. I was reading good reviews about these products and as someone who has blackout curtains I thought this could be something that would work for me. I found this particular alarm as it kept coming up in other peoples reviews. Although a bit pricey it’s not as pricey as some and you get some extra features with this too including FM radio which works well, a midnight light so you can tap it a couple of times if you need to get up in the night and you get a subtle light to help you see where you’re going instead of a bright dazzling one. You also get the choice of 7 natural sounds to add to your alarm which play at the point the alarm reaches its maximum brightness and then you can choose to tap and snooze the alarm and the sound switches off leaving the light on and then replays after 9 minutes. Some people may think 9 minutes is too long, you can’t change this either, but if you are someone who likes to snooze then just factor that in to the time you select when you actually set your alarm. You can have 2 alarms so maybe one for weekdays and one for weekends, or if you’re like me then during the week I need to be up at different times on particular days so it’s handy to have 2 alarms. I had read that some people had found this alarm difficult to set up, however once I’d got the hang of it it was fairly simple and the instructions are clear. There is also a test feature so once you have set it up you can test it to see how bright the alarm will be at full light and how loud the sound will be and then adjust as you need. Personally I set mine up at night so that in a dark room I could see how bright the alarm would get and also set the display light so it wasn’t too bright overnight, the display dims when it’s dark and brightens when it’s light. If you don’t like any light whatsoever you can turn the display off altogether and then just tap the alarm to see the time etc. You can even set a sunset duration so it will act as a lamp while you read etc and gradually dim over the duration you set and then turn off, this is a really nice way to prepare to sleep too and if you want you can add relaxing sounds to that or the radio but you don’t have to. Most importantly morning wake ups are now so much nicer! I don’t feel like I’m being dragged from sleep, my mood is nice and calm and I’m ready for the day. Love this alarm and will never go back to my shrill mobile phone. Would definitely recommend. ## Frequently Bought Together - Philips SmartSleep Wake-up Light, Coloured Sunrise and Sunset Simulation, 7 Natural Sounds, FM Radio & Reading Lamp, Tap Snooze (Model HF3531/01) - Lumie Vitamin L, Slim Light Box for Effective SAD Light Therapy, White - Beurer TL30UK SAD Lamp | Helps combat seasonal affective disorder | Daylight therapy lamp with 10,000 lux | Adjustable stand and travel bag | UV-free LED light therapy | Medical device --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/256712281-smartsleep-wake-up-light-coloured-sunrise-and-sunset-simulation-7](https://www.desertcart.gr/products/256712281-smartsleep-wake-up-light-coloured-sunrise-and-sunset-simulation-7) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-16*
