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 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.

Yes, it is still available in small Philips HF3500/60, but we don't have it in our range.

You can set two alarms to go off on the same morning. However, there is no specific information about whether you can programme the alarms with different melodies. The device offers seven natural alarm sounds and an FM radio function, but it is not explicitly mentioned that the melodies can be selected individually for each alarm.

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

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.

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,

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.

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.

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.

The lamp is bright enough on the highest setting to be used as a reading lamp.

No.

You can charge your mobile phone via the USB post.

Analogue -> FM radio

You can set the display contrast from level 1 to level 4. Unfortunately, it is not possible to switch it off completely.

The comparison function is there for a reason ;) https://www.galaxus.ch/de/Comparison/361878-5897725
