Does the model suit your lighting task?
OUILA ceiling light 28 cm round, 5 cm installation height, fixed neutral white without dimming stands in this selection for basic lighting in a hallway or small bathroom at an existing ceiling rose. It is not intended for large living spaces and not for dimmable light. 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 starts with the intended use, not with a score.
A room feels calmer when not every task depends on a single very bright ceiling light. Ambient light provides orientation, zone lighting brings brightness to a table or armchair, and accent lighting gives walls or furniture depth.
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 claim: Super bright and energy saving
What the source states: [Super bright and energy saving] The Ouila LED ceiling lamp with 24W energy saving and 2,000LM light output can supply every room with sufficiently super bright light and excellent 4,000K neutral white light, to ensure the ideal lighting for the LED ceiling lamp. High-quality LED ceiling lamps can directly replace 174W incandescent lamps, which are very energy saving and can save you more than 90% of your electricity bill
Why this matters: The amount of light can only be assessed together with beam angle, distance and the area being lit. A high figure alone does not say whether the light arrives in the right place. This equivalence claim is capped by Regulation (EU) 2019/2015. Its Table 7 assigns the figure 100 watts to 1,521 lumens and only assigns 150 watts to 2,452 lumens. At the claimed 2,000 lumens, 100 watts is therefore the highest permitted step, and 174 watts does not appear in the table at all. In the matching register entry 2685506, the field for the stated equivalent power consumption is empty. The calculation does not add up even with the listing's own figures. 24 watts instead of the claimed 174 watts is a saving of 86.2 percent, not of more than 90 percent. Above all, though, you save that share on a single light and not on the electricity bill, in which the fridge, washing machine and electronics make up the far larger part.
Listing claim: Eye protection and flicker-free
What the source states: [Eye protection and flicker-free] This improved ceiling lamp has a high colour rendering index of CRI80+. The vivid and natural light allows us to see the true and original colour of objects, which is more eye-friendly. The LED ceiling light uses a high-quality plastic lampshade shell with a light surface. Thanks to the higher light transmission, the light is distributed evenly in the room and does not dazzle, so that your eyes feel more comfortable
Why it matters: This statement comes from the sales listing and should not be read as a medical effect. A reliable assessment would need measurement methods and limit values, which a shop listing often does not state in full.
Listing claim: Waterproof, ultra-thin design
What the source states: [Waterproof, ultra-thin design] The ultra-thin design of 28 5 cm makes the Ouila ceiling light more modern and simpler, you can mount the LED ceiling lamp in a room of 9 to 20 m². Unlike other ceiling lamps, the improved LED ceiling lamp from Ouila has a waterproof IP44 certified rating, which is waterproof and prevents dust and mosquitoes from entering the light. It is described as the ideal choice as an office light, hallway light, bedroom light, bathroom light, kitchen lamp and so on
Why this matters: The IP rating is a technical limit, but not a blanket approval for every mounting location. Zone, connection and the complete installation instructions remain decisive. IP44 does not mean waterproof, and the rating does not keep dust out either. The first digit 4 stands for protection against solid foreign objects from 1 millimetre in diameter, that is against wires and larger insects, but specifically not against dust: that would need a 5 or a 6. The second digit 4 stands for splashing water from all directions. Waterproof in the sense of temporary immersion would only be a 7 in second place. In the same sentence the listing states the dimensions 28 by 5 centimetres. Five centimetres of installation height is not an ultra-thin design, and the register entries for this housing explicitly confirm the 50 millimetre depth. If a truly flat disc matters to you, look at the sister model with a diameter of 30 centimetres, which is advertised in the listing at 2.4 centimetres and entered in the register at 24 millimetres. Work out the range yourself once. The claimed 2,000 lumens give, by calculation, around 222 lux over 9 square metres and only around 100 lux over 20 square metres, in each case before losses at walls, ceiling and furniture. For a hallway and storage room the lower end of the range is enough, for a bathroom or kitchen worktop you need more like 250 to 300 lux and therefore considerably less floor area per light.
Listing claim: Anyone can install it, only a few minutes
What the source states: [Anyone can install it, only a few minutes] Simply install the base (we include all the screws you need), connect the wires, turn the LED round ceiling light onto the base, and you are done! No complex electrician knowledge is required. This LED ceiling light installation method does not require the help of an electrician. It is also very convenient for one person to install the ceiling lamp, LED lamps and ceiling lamps independently
Why this matters: This claim describes a product feature, but does not yet answer whether it is practical for basic lighting in a hallway or small bathroom at an existing ceiling rose. What matters is the link to the planned location. The light has no plug and is connected permanently to 230 volts. That is work on the fixed house wiring, regardless of how simple screwing on the base plate is. Switch off the circuit breaker, check that the circuit is dead with a suitable measuring device, and if in doubt bring in a qualified electrician. In a bathroom there is the added point that the bathroom zones of the wiring regulations (BS 7671 Section 701) must be observed.
Listing claim: High-quality after-sales guarantee
What the source states: [High-quality after-sales guarantee] Ouila has been researching lamps, hallway ceiling lamps and lanterns for many years and offers you professional technology and quality assurance. This bedroom ceiling lamp is perfect for families and the natural soft light is especially good for children's eyes! Ouila LED ceiling lights for the living room are a very well thought out idea for families. If you have any questions, please feel free to contact us
Why this matters: This is a commitment from the seller in the listing text, not manufacturer evidence and not an additional legal right. Your statutory rights apply regardless. A voluntary guarantee only counts once its terms are available in writing. There is no evidence for this statement, and the listing names none either. Only the colour rendering index can be substantiated, which the register gives as 82, with a special index R9 of 4. Lighting does not replace an eye examination, and if you notice complaints in your child, they should be clarified by a doctor and not solved with a lamp. For a child's room in the evening, 4,000 kelvin neutral white is also a deliberate choice, because warmer light usually feels calmer there.
Use in daily life
In this model the light source is permanently installed. There is no holder and no replaceable light bulb, so brightness, colour temperature and the type of dimming are fixed from the factory. At the end of its rated lifetime you therefore replace the complete light and not the lamp. That makes the purchase decision more final than with a light that has a screw-in holder.
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.
In bathrooms and outdoors, safety comes into play. An IP rating must match the actual installation location. With a hard-wired connection and uncertainty about bathroom zones, a qualified electrician is the right point of contact.
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 matched to a specific lighting task: for basic lighting in a hallway or small bathroom at an existing ceiling rose, not for large living spaces and not for dimmable light.
- 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.
The purchase usually fails here on brightness, and in both directions. If you plan the 2,000 lumens for a living area, you are at the upper end of the advertised room size at a calculated 100 lux or so and find the room gloomy. If, conversely, you trust the claim, you get a figure that appears in no OUILA registration in the EU register for this housing: there, the same 28 centimetre shade is listed at 2,300, 2,388 and 2,642 lumens, and the only OUILA registration with a round 2,000 lumens belongs to a small 22 centimetre light in class F. The second break point is the installation height: if you buy because of the word ultra-thin, you get five centimetres. If, on the other hand, you are looking for a plain neutral white light for a hallway, storage room or small bathroom, have no illusions about class F and have the connection made properly, you get exactly that in the entry-level class.
What you should measure and check before buying
Measure the installation height before buying, not just the diameter: the listing itself states 28 by 5 centimetres, and five centimetres are clearly noticeable on a low ceiling or under the edge of a wall cabinet. Then check the existing ceiling rose, that is whether the terminal under the base plate with a diameter of 28 centimetres has room and how much cable protrudes from the ceiling, because the light has no plug. Then calculate your floor area against it: 2,000 lumens give around 222 lux over 9 square metres and only around 100 lux over 20 square metres, and for a bathroom or kitchen worktop you should plan more on 250 to 300 lux. And decide deliberately on the colour temperature, because 4,000 kelvin neutral white is built in permanently and nothing can change it later.
- Define the task: Write down which surface or zone is to be lit and at what time of day you use it.
- Measure the space: Check the mounting surface, cut-out or drilling pattern, the height of the cavity and whether a fixed supply cable is present at the planned location. Product photos are no substitute for dimensions.
- 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.
- Think through the controls: The switch, app, sensor or remote control must be reachable and understandable in daily use at the planned location.
- 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 are needed depends on area and activity. Further models from this area are in the overview under home lighting, and the lighting calculator translates your room into a concrete target brightness.
Set-up, position and first check
Assign each lamp to exactly one task. Then check colour temperature, controls and possible glare in the evening. For permanently installed lamps, the installation instructions must match the existing connection; improvised solutions are not a good basis.
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 downloadable guide nor a manufacturer page, and in the event of a complaint the retailer is the only point of contact. Both are the only proof of which device you bought if you need to make a guarantee claim. Replacing the light source is not provided for, and at the end of its rated lifetime the complete device is replaced. This device is hard-wired to the house installation. Because no instructions are available for it, the connection belongs in professional hands, and all the more so in damp rooms and outdoors.
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
OUILA ceiling light 28 cm round, 5 cm installation height, fixed neutral white without dimming makes sense if you are looking for a light for basic lighting in a hallway or small bathroom at an existing ceiling rose, have checked the dimensions at the intended location and actually use the functions named in the listing. Buying is less convincing if you expect a universal solution for several contradictory 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 installation location 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 home light
How bright is it really under this light?
Neither of the two figures in circulation is fully reliable. The listing states 2,000 lumens, while the only matching entry in the EU register gives 2,300 lumens for the same housing with a diameter of 280 millimetres, a depth of 50 millimetres, 4,000 kelvin and 24.0 watts. For planning, use the 2,000 lumens from the listing, then you are on the safe side: that is around 222 lux over 9 square metres and around 100 lux over 20 square metres, before room losses.
Which energy efficiency class does the light belong to?
Class F, using the figures from the listing. 2,000 lumens divided by 24 watts is 83.33 lumens per watt, multiplied by the factor 1.176 for directional light on mains voltage this gives 98.0 lumens per watt, and class F ranges from 85 up to below 110 under Regulation (EU) 2019/2015. The matching register entry 2685506, by contrast, is in class E with 2,300 lumens at 24.0 watts, because it reaches 112.7 lumens per watt. The listing itself states no class at all.
Why is the 30-centimetre sister model brighter at the same 24 watts?
Neither of the two listing pages explains this. Both OUILA lights state 24 watts, 4,000 kelvin, CRI 80 and above, IP44 and the same room size of 9 to 20 square metres, and only the luminous flux differs, at 2,000 lumens in one case and 2,400 lumens in the other. That is 83.33 against 100.0 lumens per watt, a difference of 20 percent at supposedly identical power consumption, without any different LED generation, driver or optics being mentioned. As long as that remains so, both lumen figures are purely supplier claims.
Is the light allowed in the bathroom?
IP44 is the IP rating at which a lamp can even be considered for the splash-water area of a bathroom, but it does not make the lamp waterproof. The second digit 4 stands for splashing water from all directions, not for water jets and certainly not for immersion. What also matters is which bathroom zone above the bath or shower the lamp is meant to hang in, because the wiring regulations (BS 7671 Section 701) set requirements for that, which a qualified electrician should assess.
Can I change the colour temperature or brightness later?
No. The listing states a fixed colour temperature of 4,000 kelvin, mentions neither a remote control nor an app nor switching sequences at the wall switch, and the matching register entry explicitly lists No in the Dimmable field. If you want warm white light or would like to dim down in the evening, this is the wrong lamp, and nothing about that changes after installation.
What happens if the LED fails after some years?
Then you replace the whole lamp, because the LED is built in and has no lamp holder. The register entry shows only a dash for the cap type, which means exactly that. In the event of a fault, expect removal, a new lamp and reconnecting to 230 volts, not a light bulb change for a few pounds.
Sources and currency
The sources are ranked by their closeness to the product: manufacturer documents come before retailer or comparison data. A shop listing is useful for the variant currently on offer, but it is not an independent check. Missing documents are not replaced with invented experiences.
- Listing for ASIN B0CY5523TN with all supplier details: diameter 28 centimetres, 24 watts, 4,000 kelvin, 2,000 lumens, IP44, colour rendering index CRI80 and above, design by its own account 28 by 5 centimetres, recommended room size 9 to 20 square metres. Also the promotional claims that the light replaces 174 watt incandescent lamps, saves more than 90 percent of the electricity bill, is waterproof and keeps out dust and mosquitoes, and that installation requires no help from an electrician. The listing states a model identifier, an energy efficiency class and an EPREL number nowhere. Amazon listing B0CY5523TN, not linked
- Register entry in the EU product database EPREL for model identifier YLXDD280-24W, trade brand OUILA, registration number 2685506, entered through BELLANOVA GAETANO with an EU contact point in Madrid. The values: 2,300 lumens at 24.0 watts, class E, directional light on mains voltage, colour rendering index 82 with R9 equal to 4, peak luminous intensity 787 candela, half-value angle 113 degrees, displacement factor 0.82, flicker metric Pst LM 0.9, stroboscopic effect metric SVM 0.3, colour temperature 4,000 kelvin, not dimmable, dimensions 280 by 280 by 50 millimetres. This is the only OUILA registration whose housing dimensions, colour temperature and power consumption match this listing.
- Second register entry for the identical model identifier YLXDD280-24W, but under the trade brand Swoieltr, registration number 2361386, first published on 16 May 2025 and also registered through BELLANOVA GAETANO. All measured values are the same digit for digit: 2,300 lumens, 24.0 watts, class E, 787 candela, 113 degrees, CRI 82, R9 equal to 4, displacement factor 0.82, Pst LM 0.9, SVM 0.3, 280 by 280 by 50 millimetres. The same hardware is therefore in the register under two different trade brands.
- Register entry for model identifier JXF220-1, trade brand OUILA, registration number 2681000: 2,000 lumens at 20.0 watts, non-directional light on mains voltage, class F, colour temperature 4,000 kelvin, colour rendering index 87 with R9 equal to 30, dimensions 220 by 220 by 44 millimetres, not dimmable, flicker metric Pst LM 1.0. This is the only OUILA entry in the register that states 2,000 lumens at all, and it belongs to a considerably smaller light with a diameter of 22 centimetres.
- Register entry for model identifier YLXDD450-24W, trade brand OUILA, registration number 2660839: the same housing at 280 by 280 by 50 millimetres, but 6,500 kelvin, 2,388 lumens at 23.5 watts, class E, peak luminous intensity 554 candela, half-value angle 109 degrees, CRI 82 with R9 equal to 5, not dimmable. The entry shows that OUILA has registered the same 28 centimetre shade in several colour temperatures and states luminous fluxes between 2,300 and 2,642 lumens, never 2,000 lumens.
- Listing for the sister model of the same trade brand, ASIN B0F37W4BGN, OUILA flat round ceiling light with a diameter of 30 centimetres: 24 watts, 4,000 kelvin, 2,400 lumens, IP44, installation height 2.4 centimetres, likewise room size 9 to 20 square metres and likewise CRI 80 and above. The same brand therefore states 2,000 lumens in one case and 2,400 lumens in the other at an identical power consumption of 24 watts. Amazon listing B0F37W4BGN, not linked
- Regulation (EU) 2019/2015 on energy labelling of light sources. Annex II sets the class limits for total mains efficacy: below 85 is G, from 85 F, from 110 E, from 135 D, from 160 C, from 185 B and from 210 lumens per watt A. The correction factors are 1.176 for directional light on mains voltage and 0.926 for non-directional light that is not connected directly to mains voltage. Table 7 also limits equivalence claims for incandescent lamps: 1,521 lumens correspond to 100 watts, 2,452 lumens correspond to 150 watts.
- Regulation (EU) 2019/2020 with the ecodesign requirements for light sources. For LED light sources on mains voltage, flicker Pst LM less than or equal to 1.0 at full load applies, and since 1 September 2024 stroboscopic effect SVM less than or equal to 0.4 at full load. Both values are legal upper limits, not a quality mark.
