SEBSON bathroom mirror light 78 cm

Does the model suit your lighting task?

In this selection, the SEBSON bathroom mirror light 78 cm stands for the top edge of a mirror cabinet or a mirror up to 7 mm thick on a fixed supply cable. It is not intended as a bright make-up light or for installation without a qualified electrician. That is a narrower and more honest statement than a blanket “good” or “bad”. A lamp can be technically sound and still disappoint in the wrong place. That is why this review begins with the intended use, not with a score.

The decisive calculation is in Annex II of Regulation (EU) 2019/2015: useful luminous flux divided by power consumption, multiplied by the factor for the light source type. This light is registered as a non-directional mains light source, for which the factor is 1.000, and 1,100 divided by 15 is therefore 73.3 lumens per watt. The class limits are 85 lumens per watt for class F and 135 for class D, so this value falls into class G, and that is exactly how item number MIRROR_CAB_15W is registered in the EU product register. Class D, which the listing and manual state, belongs to model number S-101000 with 2,000 lumens at 13.6 W, which is 147.1 lumens per watt. In practice that means: 1,100 lumens correspond to roughly a 75 W incandescent bulb, spread over 78 cm of length, so around 14 lumens per centimetre. For comparison, the same brand lists a 40 cm version with 800 lumens at 8 W and a 120 cm version with 1,500 lumens at 15 W, both with 100 lumens per watt.

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

In everyday use, four dimensions and one missing part decide. The housing measures 780 × 108 × 44 mm, so it is 78 cm long although the title says 80 cm. The clamp takes mirrors up to 7 mm thick. The manual requires at least 50 cm between the light and the surface it illuminates. And the box contains only the light and two screws: no cable, no plug, no switch. It is connected to the fixed supply cable via terminals L in black or brown and N in blue or grey, and switched via the existing wall switch. The light therefore does not need a socket, but it does need a supply cable, and according to the manufacturer the connection belongs in the hands of a qualified person.

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.

What this light is not built for: as the only light source in the bathroom and as a make-up light with high colour fidelity. It gives directional light onto a narrow strip, whereas licht.de gives at least 300 lux for general lighting in the bathroom, and with Ra 80 it sits exactly at the lower limit that the same portal gives for interiors, while it calls more than 90 optimal for the mirror. The R9 value of 9 from the product data sheet confirms this for saturated red. Dimming is expressly prohibited, the colour temperature is fixed at 4,000 K, and the manual states that the item is for indoor use only and not suitable for outdoor use. For damp rooms, however, the same manual expressly declares the light suitable because of its IP44 rating, so the bathroom is not ruled out, but the balcony is. If you want to assess your own skin condition in the mirror, you should not rely on the light for that anyway: anything unusual should be checked by a doctor, and a lamp does not replace an examination.

Strengths and limits of the assessment

This purchase most often fails because of the expectation that the energy class creates: the page says D, the figures next to it give 73.3 lumens per watt and therefore a G, and 1,100 lumens over 78 cm is the thinnest light in the whole SEBSON range. The second trap is installation, because a clamp light sounds like a quick job, but the manufacturer's manual actually requires installation by a qualified person on exposed mains voltage, and the box contains only two screws. Third, the mix-up within the brand itself: two listings with word-for-word identical text differ by 200 lumens and one energy class, recognisable only from the item number. And fourth, the minimum distance of 50 cm to the illuminated surface, which only appears in the manual and is easily undercut above a shallow mirror cabinet.

What you should measure and check before buying

First measure the width of the mirror or of the mirror cabinet's top edge and compare it with the 780 mm of the housing, because the light is 78 and not 80 cm long. Then use callipers or a ruler to measure the thickness of the mirror at the point where the clamp is to sit, and stay within the upper limit of 7 mm. Third, measure the vertical distance between the planned light position and the surface to be illuminated, because the manual requires at least 50 cm. And before buying, check whether a switched supply cable ends at this point, because the box contains only the light and two screws, no cable and no plug.

1. Clarify the task: First decide whether you are looking for a mirror light or a ceiling light for the bathroom. These are two different tasks: this light illuminates the area in front of the mirror, and it does not provide the 300 lux of general lighting that licht.de mentions.
2. Clarify the supply cable: Check whether a switched supply cable ends at the planned location, because the delivery consists of the light and two screws. The manual requires installation by a qualified person because it involves work on the mains voltage.
3. Match the dimensions: Compare the mirror width with the 780 mm housing length and the mirror thickness with the upper limit of 7 mm for the clamp. Also allow for the minimum distance of 50 cm to the illuminated surface that the manual requires.
4. Put the brightness in context: Calculate 1,100 lumens divided by 15 W equals 73.3 lumens per watt, and because the factor 1.000 applies to non-directional mains light, that is already the final result. Check whether that is enough for you. It corresponds to roughly a 75 W incandescent bulb, spread over 78 cm, and is the lowest light density of the SEBSON mirror lights.
5. Check the item number: Check the item number row in the listing table. MIRROR_CAB_15W is the version with 1,100 lumens and a class G registration, MIRROR_CAB_C78 the one with 1,300 lumens and a class F registration, and both run under model number S-101000 with the same displayed class D.

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

Installation starts at the fuse box and not with the screwdriver. Switch off the circuit, remove the fuse and check the cable with a voltage tester, because the light is connected to 230 V without a control gear. Then decide the position: centred above the mirror, with at least 50 cm to the illuminated surface, and outside zones 0, 1 and 2 or at least so that the IP44 rating suits the zone. Before drilling, check whether cables or pipes run at the drilling point. If you use the clamp version, measure the mirror thickness beforehand and stay under 7 mm, otherwise the clamp will not hold properly. Finally connect L and N, put the fuse back in and switch on via the wall switch, as the light has no switch of its own.

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.

Keep the instructions and the model designation. This helps with spare parts, with a later query about the product and in a guarantee case. Replacing the light source is not intended; at the end of its rated lifetime the whole device is replaced. For a hard-wired mains connection, damp locations and outdoor mounting, the rule is: if the existing installation does not clearly match the instructions, the work belongs in professional hands.

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

The SEBSON bathroom mirror light 78 cm makes sense if you are looking for a mirror light for the top edge of a mirror cabinet or a mirror up to 7 mm thick on a fixed supply cable, have checked the dimensions at the intended location 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 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?

The page itself gives no figure for the colour rendering index or the energy efficiency class.
• The manufacturer's installation and operating manual for MIRROR_CAB_15W as a PDF, German and English parts. Delivery one mirror light and two screws for fixing, so neither cable nor plug. Four sentences there decide the purchase: installation must be carried out by a qualified person in line with the applicable electrical and installation regulations, installation requires work on the mains voltage and the circuit must be disconnected beforehand, the built-in light source cannot be replaced, and no dimmer may be connected. Also the mounting notes: use indoors only, allow a minimum distance of 50 cm between the illuminated surface and the light, connect with L as the live conductor in black or brown and N as the neutral conductor in blue or grey. The manual's data block gives 220 to 240 V alternating current, 15 W, rated luminous flux 1,100 lumens, 4,000 K, IP44 and Class II, and below it the sentence that the product contains a light source of energy efficiency class D.
• EU product register EPREL, registration 731337 of the checked trading brand SEBSON for the model identifier MIRROR_CAB_15W, registered via SEBSON, Inh. Sebastian Sonntag, on the market since 22 June 2018. Entered are 1,100 lumens at 15 W, energy efficiency class G, 4,000 K, colour rendering index 80 with an R9 value of 5, mains light source, flicker metric 0 and stroboscopic effect 0, housing dimensions 800 × 108 × 40 mm. It is registered as a non-directional light source with a direct mains connection, and for that, Table 2 in Annex II of the regulation gives the factor 1.000, so the division is already the final result: 1,100 divided by 15 gives 73.3 lumens per watt, which is below the F limit of 85 and therefore squarely in class G. This registration therefore matches exactly the figures that the listing, shop page and manual give, and it lists a different class from the listing.
• EU product register EPREL, registration 2372296 of the trading brand SEBSON for the model identifier S-101000, that is the model number that the listing's attribute table gives and to which the shop page itself links. Entered are 2,000 lumens at 13.6 W, energy efficiency class D, 4,000 K, colour rendering index 80 with an R9 value of 9, mains light source, non-directional, not dimmable, flicker metric 0 and stroboscopic effect 0, housing dimensions 780 × 44 × 134 mm, on the market since 1 December 2024, published on 30 May 2025. This entry also describes a non-directional mains light source, so the factor 1.000 applies here too: 2,000 divided by 13.6 gives 147.1 lumens per watt, and that falls in class D, which runs from 135 to under 160 lumens per watt. This registration therefore adds up on its own, it simply describes a light that is almost twice as bright as the one whose data appear everywhere beside it.
• EU product register EPREL, registration 731398 of the trading brand SEBSON for the model identifier MIRROR_CAB_C78: 1,300 lumens at 15 W, energy efficiency class F, 4,000 K, colour rendering index 80 with an R9 value of minus 1, flicker metric 0, housing dimensions 780 × 78 × 44 mm, on the market since 1 October 2020. Non-directional mains light source, so again factor 1.000: 1,300 divided by 15 gives 86.7 lumens per watt, which is just above the F limit of 85. The same power consumption as MIRROR_CAB_15W, 200 lumens more and one class better.

• licht.de on lighting in the bathroom. For general lighting, the portal gives at least 300 lux. For the mirror, it recommends two identical lights to the right and left of the mirror so that the face is lit without shadows, and gives at least Ra 80, optimal more than 90, as the colour rendering requirement.
• licht.de on installation in the bathroom under the German standard DIN VDE 0100-701. Zone 0 is the interior of the bath and shower tray, where only safety extra-low voltage up to 12 V alternating voltage and IPX7 are allowed. Zone 1 extends up to a height of 2.25 metres, for a free-standing shower within a radius of 120 centimetres around the shower head, and requires IPX4. Zone 2 is 60 centimetres wide and requires IPX4, or IPX5 with massage jets. Outside the zones, no increased requirements apply. In zones 0, 1 and 2, neither switches nor sockets may be fitted.
• licht.de, lighting lexicon entry on the colour rendering index. The index Ra shows how naturally colours are rendered in the light of a lamp, where Ra equal to 100 is the highest possible value. In interiors, Ra 80 should not be undercut; for areas with special requirements for colour judgement, values above 90 are suitable.
• licht.de on the energy efficiency classes of light sources that have applied since 1 September 2021, with the class limits of luminous efficacy: A from 210 lumens per watt, B from 185 to 209, C from 160 to 184, D from 135 to 159, E from 110 to 134, F from 85 to 109 and G below 85 lumens per watt.
• Overview of the IP ratings under BS EN 60529 (German edition DIN EN 60529 and VDE 0470-1) with the table of the second digit: 4 splashing water, 5 water jets, 6 powerful water jets, 7 temporary immersion, 8 continuous submersion. This shows that the term waterproof at IP44 means no more than splash protection.
• Section 13 of the German Low Voltage Connection Ordinance (NAV): Electrical installations beyond the service fuse may be installed, extended, altered and maintained, other than by the network operator, only by an installation company entered in a network operator's register of installers.
• Regulation (EU) 2019/2015 in the consolidated full text, Annex II with the calculation method. The energy efficiency class of a light source is determined from the total mains efficacy, which is calculated as the useful luminous flux divided by the on-mode power consumption, multiplied by a factor from Table 2. This factor depends on the light source type: 1.000 for non-directional light with a direct mains connection, 0.926 for non-directional light without a direct mains connection, 1.176 for directional light with a direct mains connection and 1.089 for directional light without a direct mains connection. Table 1 gives the class limits of the total mains efficacy: A from 210, B from 185, C from 160, D from 135, E from 110 and F from 85 lumens per watt, below that class G.
