ONSTUY WS8816B RGB corner lamp 1.6 m, Bluetooth, no documented lumen figure

Does the model suit your lighting task?

ONSTUY WS8816B RGB corner lamp 1.6 m, Bluetooth, no documented lumen figure stands in this selection for coloured mood lighting in a corner of the room. It is not intended as the general lighting of a room. 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 analysis starts with the intended use, not with a score.

A floor lamp always works together with its position. Next to an armchair a directed head can make sense, in a dark corner indirect light on the wall or ceiling often feels calmer. In the middle of the room, by contrast, it quickly becomes obvious whether the base, cable and shade get in the way in daily use.

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.

Product data and sources

Use in daily life

For the general lighting of a whole living room, a single point of light is seldom enough. That also applies to bright uplighters. Good home lighting spreads several tasks: orientation, reading, conversation and accent lighting do not have to come from the same lamp.

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.

Before buying, a simple trial in the evening is worthwhile. Switch on only the existing ceiling light and mark the spot where you lack light. Only then can you judge whether an arc lamp, an uplighter, a reading lamp or a pure accent light is the right design.

Strengths and limits of the assessment

The reading that this is a living room lamp is misleading. The listing gives not a single lumen value, so the luminous flux is unknown, and the only official document on the page gives 196 lumens for a different model. Anyone who derives certainty from the energy label on file is also mistaken: label and data sheet carry an unrelated company name and an unrelated model identifier, and they describe a 122 centimetre tall, non-dimmable and non-coloured light source. The attribute values 3 watts and class G also come from this unrelated registration. The item dimensions of 40 by 40 by 400 millimetres and the 280 grams are misleading too, because they describe a single tube segment and not the assembled lamp.

Why the data sheet on file describes a different lamp

An EU energy label and a product data sheet are attached to the listing. Neither belongs to this model. They are issued to the company Shenzhen AIME Cloud Chuang with the model identifier EISS-CIMI-12 and the EPREL number 2311977, and the entry describes a light source with 196 lumens, 2.6 watts, fixed 6100 kelvin, expressly not dimmable and expressly not colour tunable. What is sold here is a dimmable RGB lamp with 16 million colours. The only official document thus contradicts the listing on almost every point.

The cause lies in the variant structure. The listing bundles four variants: 1.2 and 1.6 metres, each as a single unit and as a twin pack. The height of 1220 millimetres given in the data sheet matches the shorter variant with the model number WS8812B, not the 1.6 metre version WS8816B sold here. There is no separate registration for this one, and a query of the EPREL database by brand and model number returns no results.

This leads to the key finding of this page: for this lamp, no luminous flux is documented anywhere. Neither the title, nor the listing bullet points, nor the attribute table gives a lumen value. We therefore cannot say how bright it is, and we do not place it as room lighting. The only reference point is the 196 lumens of the shorter sister model, and that is the order of magnitude of an orientation light. The attribute values 3 watts, class G, 40 by 40 by 400 millimetres and 280 grams do not help either: the first two come from the same unrelated registration, the last two describe a single tube segment and not the assembled lamp.

What you should measure and check before buying

First measure the corner where the lamp is to stand, because 160 centimetres of height appears only in the listing and the only official height figure in the data sheet on file is 122 centimetres. Check which variant you have in your basket, because the listing offers four variants of 1.2 and 1.6 metres, as single units and twin packs, and the model number switches between WS8812B and WS8816B. Measure the distance to the socket and allow room for the power supply, because no source gives cable length, voltage or plug type. Finally, check whether your phone allows Bluetooth pairing, because there is no Wi-Fi connection.

1. Define the task: Write down which surface or zone is to be lit and at what time of day you use it.
2. Measure the space: Check the standing or mounting surface, height, cable route and reachable socket. Product photos are no substitute for measurements.
3. Compare the light data: Check light output, colour temperature, dimming and, if needed, IP rating in the current listing text. There is no manufacturer document to consult for this item.
4. Think through the controls: The switch, app, sensor or remote control must be reachable and understandable in daily use at the planned location.
5. Check the variant: Colour, size and set contents can differ within one listing, and often the technical details in the description text with them. Compare the selected variant with this analysis.

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 from this area are in the overview under floor lamps, and the lighting calculator turns your room into a concrete target brightness.

Set-up, position and first check

First place the lamp at the intended spot without an extension lead. Align the light head while seated, check for reflections in the television and check whether the switch is within reach. The light source is built in: lamp holder, choice of light bulb and dimmer compatibility do not apply, and instead the built-in control decides brightness and colour temperature.

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 down the model number and order date and keep whatever paper is in the box. For this item there is neither an instruction manual nor a manufacturer page to download, and in the event of a complaint the retailer is the only point of contact. You need both when you set up the app again and in a guarantee case, because there is no data sheet to look things up in. Replacing the light source is not provided for; at the end of its rated lifetime the complete unit 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

ONSTUY WS8816B RGB corner lamp 1.6 m, Bluetooth, no documented lumen figure makes sense if you are looking for a lamp for coloured mood lighting in a corner of the room, 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?
