Does the model suit your lighting task?
Osram Superstar Plus Classic A 60 Filament, E27, dimmable, 806 lm, 2700 K stands in this selection for existing E27 lamp holders with a leading-edge or trailing-edge dimmer switch, dimmer type not confirmed without a manufacturer list. 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.
The decisive figure is efficiency: 806 lumens at 5.8 watts is around 139.0 lumens per watt, and at 5.9 watts it is around 136.6. The record in the EU product register lists the lamp as non-directional and mains-operated, so the factor from Annex II of Regulation (EU) 2019/2015 is 1.000. That gives class D, with the threshold at 135 lumens per watt.
The listing carries 8 usable product features. The 6 most informative are assessed individually below. They are not presented as independently confirmed measurements. We expressly 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 our house punctuation: dashes become a colon or comma, ranges of values are written out with “to”, special characters and advertising symbols are removed. Figures, units and statements remain untouched.

Listing claim: Very low energy consumption, latest LED technology
What the source states: Very low energy consumption, latest LED technology
Why this matters: This claim describes a product feature, but does not yet answer whether it is practical for existing E27 lamp holders with a leading-edge or trailing-edge dimmer switch, dimmer type not confirmed without a manufacturer list. What counts is the link to the planned place of use. The registrations run from 2021 to 2026, so one version dates from before 2023. A statement about the technical state of the art cannot be verified from that. What is verified is 806 lumens at 5.8 or 5.9 watts and class D.
Listing claim: Very long rated lifetime, up to 25000 hours…
What the source states: Very long rated lifetime, up to 25000 hours and up to 100000 switching cycles. Warm white light for comfort and relaxation in living rooms, bedrooms and children’s rooms
Why this matters: The stated colour temperature describes the effect, not the brightness. In everyday use, what matters is whether fixed steps or a continuous range are offered and whether the setting is saved. The Ledvance manufacturer’s page gives 15,000 hours for this model, whereas the listing gives 25,000. The EU product register lists no number of hours, but a lumen maintenance of 0.93 and a survival rate of 0.9. Which figure applies to your pack is not verified, and if in doubt the lower manufacturer figure applies. This figure appears neither on the manufacturer’s page nor in the EU product register. It remains a claim by the seller without evidence.
Listing claim: Full light instantly, no warm-up time. Easy…
What the source states: Full light instantly, no warm-up time. Easy replacement of conventional lamps (outdoor use only in suitable light fittings)
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 claim: Lower heat generation
What the source states: Lower heat generation (compared with the standard reference product).
Why this matters: This claim describes a product feature, but does not yet answer whether it is practical for existing E27 lamp holders with a leading-edge or trailing-edge dimmer switch, dimmer type not confirmed without a manufacturer list. What counts is the link to the planned place of use. The addition compared with the standard reference product turns it into a comparison with the incandescent bulb. No statement about the housing temperature in operation is made with it, and we have not measured anything.
Listing claim: Best quality from the Osram brand
What the source states: Best quality from the Osram brand
Why this matters: This point should be checked against the dimensions, instructions and existing installation before you buy. A listing can contain variants or shortened wording.
Listing claim: 31.0 grams
What the source states: 31.0 grams
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.
Use in daily life
In everyday use, lamp holder and space count: the lamp is screwed into an existing E27 lamp holder, and a fixed installation or a dedicated standing surface is not needed. According to the manufacturer it is 105 millimetres long and 60 millimetres in diameter, and in very narrow shades you need to re-measure. When connected to a dimmer switch, the manufacturer’s compatibility list applies.
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.
Scope: the lamp is not a light fitting with a built-in LED, it is not a spotlight with directional light and not a smart lamp without a wireless standard and without a hub. For outdoor use the documents give no IP rating, and there the IP rating of the light fitting decides. Light therapy does not replace medical treatment, and statements about wellbeing or sleep are not verified.
Strengths and limits of the assessment
What speaks for the model
- Product image, ASIN and listing data are clearly linked to one another.
- The shape can be matched to a specific lighting task: for existing E27 lamp holders with a leading-edge or trailing-edge dimmer switch, dimmer type not confirmed without a manufacturer list.
- 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.
This purchase typically fails at the dimmer switch: the lamp is dimmable, but without a confirmed dimmer type an old device with a minimum load can make it flicker or switch off. Then there is the rated lifetime, where the listing and the manufacturer’s page diverge. And because several model numbers carry the same GTIN, you do not know before buying which registration is in your pack.
What you should measure and check before buying
Measure the free length and the diameter of your light fitting, because the lamp is 105 millimetres long and 60 millimetres in diameter according to the manufacturer. If you have an existing dimmer switch, also read off the model and minimum load and compare them with the manufacturer’s compatibility list. Finally, check the model number on the packaging, because three variants with 5.8 or 5.9 watts share the same GTIN.
- Define the task: Clarify whether you need a replacement for a 60-watt incandescent bulb in an E27 lamp holder or a lamp with a directional beam. These are two different lamp classes.
- Lamp holder and dimensions: Check the E27 lamp holder and re-measure the free length and the diameter. According to the manufacturer, these are 105 and 60 millimetres.
- Match the dimmer switch: Read off the model and minimum load of your dimmer switch and compare both with the manufacturer’s compatibility list.
- Colour temperature and colour rendering: According to the manufacturer, 2700 Kelvin and Ra 90. Check whether that suits your other lamps in the room.
- Check the model identifier: Read the model number off the packaging, because AC33980, AC45155 and AC92562 share the same GTIN and differ in power and lumen maintenance.
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
When fitting, what counts is that the power is off and the lamp sits firmly in the E27 lamp holder. If you dim, compare the dimmer switch model and minimum load with the manufacturer’s compatibility list and, if in doubt, fit a single lamp first. For a fixed 230-volt connection without a plug, for example on the ceiling, if in doubt the route via a qualified electrician applies.
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 claim. The light bulb and lamp holder remain replaceable, so a later change of brightness or colour temperature is possible. This device is intended for indoor use only, and it is not approved for damp rooms or outdoor use.
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
Osram Superstar Plus Classic A 60 Filament, E27, dimmable, 806 lm, 2700 K makes sense if you are looking for a lamp for existing E27 lamp holders with a leading-edge or trailing-edge dimmer switch, dimmer type not confirmed without a manufacturer list, have checked the dimensions at the intended place and 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 lamp
Which class does the Osram Superstar Filament with 806 lumens have?
Class D on the scale from A to G. The calculation with the factor 1.000 for non-directional, mains-operated light sources gives around 139.0 lumens per watt at 5.8 watts and around 136.6 at 5.9 watts, and the threshold for class D is 135.
Is the lamp dimmable, and with which dimmer switch?
It is dimmable according to the manufacturer and according to the EU product register. The documents retrieved do not state which dimmer type applies, trailing-edge or leading-edge. The manufacturer’s page refers to a compatibility list, which you should check against your dimmer switch model before buying.
How long does the lamp last, 15,000 or 25,000 hours?
The manufacturer’s page from Ledvance gives 15,000 hours, while the listing gives up to 25,000 hours. The EU product register lists no number of hours, but a lumen maintenance of 0.93 and a survival rate of 0.9. If in doubt, work with the lower manufacturer figure.
How good is the colour rendering?
According to the manufacturer, the colour rendering index is Ra 90, and 90 is also entered as the minimum value in the EU product register. That is a decent value for home lighting, but we cannot say anything about how individual colours look under this lamp, with no documented hands-on testing.
Is Osram still the manufacturer here?
The manufacturer documents list the lamp under Ledvance, which uses the Osram brand for lamps. In the EU product register, LEDVANCE GmbH is entered as the registrant. For questions about the warranty or the dimmer list, Ledvance is therefore the contact.
Will the lamp fit my E27 lamp holder, and what size is it?
Yes, the cap is E27. According to the manufacturer’s page, the lamp is 105 millimetres long and 60 millimetres in diameter, which corresponds to the classic bulb shape. In very narrow shades or globe lights, you should measure the length and diameter beforehand.
