No, the alarm clock does not have a radio-controlled clock.

This is the HF3531/01 model, which also has an integrated FM radio.🫡

The more expensive one also has 2 more alarm tones. Otherwise, the products are the same except for the colour.

The light itself turns off completely. The time can be dimmed or switched off in four levels. I have the time on the lowest level and it doesn't bother me. As soon as the light turns on, the time is set to the brightest level and dims again when you turn off the light.

In contrast to the Philips Wake-Up Light, the Philips Smart Sleep does not have a built-in radio module (so it is not a clock radio). Otherwise they differ only slightly in colour.

No only works with mains operation

I'll ask my crystal ball. Then I'll get back to you

Yes, the Philips SmartSleep Wake-up Light HF3519/01 has a "sunset function". This function simulates the natural sunset by gradually dimming the light, which helps you relax and fall asleep in the evening.

The Philips SmartSleep Wake-Up Light HF3531/01 must always be connected to electricity to function, as it does not have a battery or any other power source besides an electrical connection.

Yes, the Philips SmartSleep Wake-up Light HF3519/01 includes a sunset simulation function to help you fall asleep. This function, called "sunset simulation", gradually dims the light over a period of time that you can define, helping to prepare your body for sleep.

No, it doesn't have a built-in sleep phase alarm, but the light automatically wakes you up when you are in a lighter sleep phase.

Hi, Djouffe Do you mean, A) using the unit as a light source only? Or do you mean, B) that the light comes on (when the time is set) without any sound coming out? Greetings,

Now ordered a second wake-up. However, I still need a replacement power supply and would be happy to receive an answer from Galaxus!

We are sorry to hear that you are not satisfied with the product. Please feel free to leave a product review.

Hello Sebasladem12, I haven't even thought about this option and don't know how seriously it is meant. I don't think it would work with the alarm clock - it would have to be adjusted daily. With this wish, I would open the curtains and blinds - and do without the alarm clock :) Merry Christmas!

On my alarm clock, the light comes on 30 minutes before the alarm tone (birds).

Yes, you can set how long it takes for the light to go out. Then it dims very gently until it is completely dark. I think it's a great function!

Unfortunately, the desired spare part is not currently available in our online shop. Please contact our customer service directly so that a spare part request can be initiated for you and the further procedure can be discussed with you individually: https://helpcenter.galaxus.ch/hc/de/requests/new

I can't tell you in lumens because I don't have the corresponding test device. In the wake-up function, the lowest level is such that you only notice it when your eyes are open. In the lamp function (i.e. the lamp is consciously switched on, e.g. for reading), the lowest level is perceptible when the eyes are closed. If you tell me a test procedure, I will be happy to try it out for you.

My son has also unplugged his Philips Wake-up Light as it has been coming on in the night and not with the alarm setting … although I have not tested this myself (dad) … but he has stopped using it for same readon 😢

Hello These are birdsong, a piano, the sound of the sea, a harp or a cuckoo. This makes waking up much more relaxed and less abrupt than with the "normal" alarm tone.

I only unplugged the unit for a few seconds and the settings were retained. I cannot say what happens in the event of a power failure.

Each individual part has its own serial number. Here, the manufacturer's reference is HF3519/01. You can find this information in the specifications.

HF3531/01 has a night light: soft reddish light, also has the colour orange at sunset and sunrise (3520/01: white, yellow, amber, red), the duration of sunrise and sunset is adjustable between 10 - 60 minutes instead of 20 - 40 minutes (source: Amazon).

No, there are only sounds of alarm clocks and the radio.

Birdsong, waterfall, etc., or radio stations. The volume can increase slowly or quickly. But what's really stupid is that you can't set the alarm clock by day of the week, and summer and winter time are not updated.
