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.
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.
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.
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.
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).
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.
When touching the alarm, make sure that you touch the luminous dots under the inscription.
If you have done this and it still doesn't work, it can only be a malfunction and the alarm clock must be exchanged.
it works fine for me. what i haven't found out yet, however, is that the menu buttons on the outside of the rim should light up in the dark when you get close to them. but that's not a bad thing, because you can quickly find the position of these functions by heart.
otherwise, i'm thrilled with the product. especially the night light is great. you can get up without waking your partner and still see where you're going.
