The Light Alarm Clock by Philips convinces not only with its modern, timeless design but above all, with its easy handling and the various adjustment possibilities. With the help of the sunrise simulation, waking up in the morning is quite pleasant. Unfortunately, however, the snooze function often does not work properly or only with a lot of effort, which is a pity, as this light alarm clock otherwise performs very well in all other areas.

The product

Lichtwecker von Philips
Light Alarm Clock by Philips

The Light Alarm Clock by Philips comes in a small, handy package. The most important details and characteristics of the light alarm clock are described on this packaging and thus gives a good overview of the product in advance. The light alarm clock comes in a simple, timeless design. The material of this alarm clock consists mainly of plastic. The display is clearly arranged with 4 key functions each (light setting: Intensity on a scale of 0-10 selectable, as well as alarm button) below the clock indicator and 5 button functions (volume adjustable, radio button and forward and rewind button) above. On the back, there is the stand, the 3 further button functions (alarm tone adjustable, button to switch off the display completely), as well as a connection for the main cable which is 1.5 m long. Due to the brightness setting, this alarm clock can also be used as a bedside lamp.

Included in delivery:

  • Light alarm
  • Instruction manual
  • Power cords
  • Warranty booklet

Light Alarm Clock from Philips

The Light Alarm Wake-Up Clock from Philips is simple and self-explanatory. To turn on the alarm clock, first, connect the power cord to the alarm clock. Then the numbers on the display light up red. With the "+" and "-" keys you can first enter the current time. To do this, simply hold one of the two buttons down for a long time. Once you have set the time, you can now adjust the alarm time individually. To do this, press the "Alarm clock" button and set the time. In order to be able to adjust the light intensity, one must hold the "sun"-key pressed longer, then one can select between 0-10. The setting of this alarm clock works flawlessly and without problems. The light resembles a sunrise. It is also possible to switch off the display completely overnight without losing the alarm settings.

Sunrise simulation:

Within 30 minutes the alarm clock becomes brighter and brighter. The body is pleasantly aware of the slow change in light and does not wake up abruptly. The two alarm tones (birdsong) are also completely authentic and make waking up easier.

Smart Snooz function:

There were some problems with the Smart Snooze function. According to the manual, you only have to put your fingers on the upper edge of the alarm clock. This did not work properly. The snooze function only worked when pressing the alarm button hard and lifting it up. Another disadvantage is that the entire setting disappears as soon as you unplug the power cord.

Radio function:

The radio function works very well thanks to the long antenna cable. You can turn on the radio at any time or use it as an alarm tone.
