Does the model suit your lighting task?
JALL Full-Screen Wake Up Light, wake-up light with sunrise and FM radio stands in this selection for waking with slowly rising light and sound at the bedside. It is not intended for daytime light use. That is a narrower and more honest statement than a blanket “good” or “bad”. A lamp can be technically decent and still disappoint in the wrong place. That is why this review begins with the intended use, not with a score.
No illuminance is documented for this model. A wake-up light is not a SAD lamp, and without a documented lux value its brightness cannot be placed in context. If you are looking for bright light use in winter, this device is the wrong choice. That does not make the alarm clock worse, it describes a different job.
For this model there are 5 readable product features from the Amazon listing. They are not presented as independently confirmed measured values. We explicitly separate what the source states from our practical assessment. We do not claim any long-term, laboratory or room trials of our own. We reproduce the quoted listing texts unchanged in content, but apply the house style for punctuation: dashes become a colon or comma, ranges are written out with “to”, and special characters and advertising symbols are removed. Numbers, units and statements are left untouched.

Listing statement: Full-screen sunrise simulation for deep sleepers:, This…
What the source says: Full-screen sunrise simulation for deep sleepers:, This sunrise alarm clock simulates the natural dawn and gently raises the light from dark to full brightness 10 to 60 min before the alarm. Thanks to the large full-screen display, even deep sleepers are woken without shrill sounds, for a stress-free start to the day
Why this matters: With a sensor, detection angle, range, mounting height and possible false triggering count. These points cannot be fully derived from a bare mention of a function. How bright the surface becomes is not documented by any source: neither the listing nor the brand site nor the manuals of related JALL models give a lux value for this device.
Listing statement: Dual alarm, snooze & automatic time synchronisation…
What the source says: Dual alarm, snooze & automatic time synchronisation:, Individual alarm profiles for everyday, weekdays or weekends. The snooze function is flexible (5 to 20 min). Via Bluetooth the time synchronises automatically with your smartphone, so manual setting is not needed. Perfect for couples and families
Why this matters: Adjustability is only useful if the range of movement stays free at the planned location and the lamp holds its position reliably.
Listing statement: 25 nature sounds, white noise & FM radio:, Fall asleep…
What the source says: 25 nature sounds, white noise & FM radio:, Fall asleep to 25 soothing nature sounds and white noise. The timer can be set from 10 to 480 min. The L0 screen blackout mode provides absolute darkness. The built-in FM radio (76 to 108 MHz) scans automatically for stations as an alarm sound
Why this matters: For the assessment, what counts is whether this feature brings a concrete advantage in daily use. Without a suitable lighting task, it remains mainly a data sheet point.
Listing statement: RGB ambience & 5W Bluetooth speaker:, Experience…
What the source says: RGB ambience & 5W Bluetooth speaker:, Experience 17 light effects (8 single-colour & 9 RGB modes) including a music rhythm mode. The powerful 5W speaker streams crystal-clear sound from your phone, a clear step up in quality compared with conventional alarm clocks with weak sound
Why this matters: This statement describes a product feature, but does not yet answer whether it is practical for waking with slowly rising light and sound at the bedside. What matters is the connection to the planned location.
Listing statement: Intuitive operation & ideal as a gift:, Thanks to…
What the source says: Intuitive operation & ideal as a gift:, Thanks to clearly arranged buttons it is ready for use immediately. With its modern design, this alarm clock is a functional eye-catcher in the bedroom. A perfect gift for birthdays, Christmas, parents or seniors.
Why it matters: Check how many ways of operating it there really are and whether each of them stays reachable at the planned spot. It is also important whether the device saves the last level chosen and whether an accidental touch changes a setting.
Use in daily life
In everyday use, the space on the bedside table decides. The device needs a free surface, a reachable socket and a position from which the full-screen surface comes into view when lying down without shining directly at you. If you find every light source disturbing at night, plan to use the blackout mode, which switches the screen dark.
For this model, the purchase decision should therefore hinge on a concrete situation. Before buying, write a sentence such as: “I need light for …” and add place, time of day and activity. If the model does not clearly fulfil this task, an alternative from the same category is probably the better choice.
A wake-up light is a comfort device and not a medical product. Light use does not replace medical treatment. In the case of persistent sleep problems, low mood, eye conditions, photosensitising medication or mental illness, clarification beforehand belongs in qualified hands.
Strengths and limits of the assessment
What speaks for the model
- Product image, ASIN and listing data are clearly linked to one another.
- The design can be assigned to a specific lighting task: for waking with slowly rising light and sound at the bedside, not for daytime light use.
- The available features allow a targeted check before buying, without inventing a star rating.
What remains open
- No long-term use of our own, no light measurement and no documented load check.
- Listing details can be abbreviated or change with variants and model updates.
- Room effect, glare and ease of use depend on your location and daily routine.
If you are looking for bright light use for dark winter mornings, you will miss the goal here: for this model no document gives a lux value. That also undermines the promise of waking deep sleepers through the full-screen surface alone. For getting up, therefore rely on the second wake-up route via nature sound, speaker or radio and treat the light as an extra. There is no manufacturer data sheet against which you could check this beforehand.
What you should measure and check before buying
Do not plan around a lux figure here, because neither the listing nor the brand site nor the manuals of related models give a photometric value for this device. Instead, measure the free surface on the bedside table and the height of the shelf relative to your pillow, because that determines whether the light surface is in your field of view on waking at all. Check the line of sight when lying down so that the full-screen surface does not shine directly at you, and measure the route from the bedside table to the socket. If every light source disturbs you at night, plan in the blackout mode, which switches the screen dark.
- Define the task: Clarify whether you want a gentle wake-up light or bright light use during the day. These are two different device classes.
- Measure the space: Check the bedside table surface, the height relative to the pillow and the cable route to the socket.
- Define the wake-up route: Plan nature sound, speaker or radio as a second wake-up route and do not rely on the light alone.
- Think through the night: Clarify whether a glowing display disturbs you at night, and check the blackout mode.
- Accept the source base: For this model there is no data sheet with a lux value. If you need a documented figure, this is the wrong device.
If you are unsure how much light your room needs at all, work it out once: the lumens-to-watts chart translates wattage figures into actual brightness, and how many lumens per room you need depends on floor area and activity. More models in this area are listed in the overview of SAD lamps, and the lighting calculator turns your room into a concrete target brightness.
Set-up, position and first check
Set the wake-up time and sunrise duration and plan a sound in addition from the start, because you should not rely on the light alone with this device. Set up the alarm clock so that the light surface stays visible when lying down. Check the controls once in the dark, because when half asleep every movement counts.
After set-up, do not judge the light only in daylight. In the evening, switch the rest of the lighting as you normally use it, and check the situation from seated, standing and walking height. Only then do disturbing reflections, hard shadows or an unfavourable switch position become visible.
Note the model number and order date and keep whatever paperwork is in the box. For this item there is neither a manual nor a manufacturer page to download, and in a complaint the retailer is the only point of contact. Both are, in a guarantee claim, the only proof of which device you bought. Replacing the light source is not provided for, and at the end of its rated lifetime the complete device is replaced.
Comparison with similar models
The comparison does not name winners. It shows models of the same category so that you can see whether one of them is closer to your lighting task. If two models have the same task in the Assessment column, they do not differ in purpose but in design, dimensions and features. The column then states what is actually different according to the sources.

Our buying decision
JALL Full-Screen Wake Up Light, wake-up light with sunrise and FM radio makes sense if you are looking for a device for waking with slowly rising light and sound at the bedside, have checked the dimensions at the intended spot and will actually use the functions named in the listing. The purchase is less convincing if you expect a universal solution for several conflicting lighting tasks.
Keep looking if key data such as dimensions, light output, IP rating or compatibility is not clearly documented for your intended use. The same applies if you only like the look of the design, but the cable, the floor space or the controls would get in your way in daily use.
We deliberately award no stars. A numerical score would suggest a measurement accuracy that does not exist without documented hands-on testing. The statement this page can support is narrower: which details are available, what the model may be suited for, and which questions remain open before you buy?
Frequently asked questions about the JALL wake-up light
Can high lux figures be reached at any distance?
No. Illuminance falls off sharply with distance. The measuring distance therefore always belongs with a lux figure, and where no source gives it, the number cannot be compared.
Can I simply leave the lamp on all day?
That is not the usual way to use it. Follow the instructions for the device and have any health concerns clarified by a doctor.
Is a larger light surface better?
It can allow more freedom of movement, but it is less compact. What matters is whether surface, distance and daily routine fit together.
Is a wake-up light a SAD lamp?
No. A wake-up light simulates a sunrise. A SAD lamp works with a defined bright application and has its own safety notes.
