Does the model suit your lighting task?
Osram Superstar Classic A 60 Filament DIM, E27, 5.9 W, 806 lm, 2700 K stands in this selection for existing E27 lamp holders with a trailing-edge dimmer, without a documented dimmer 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 starts with the intended use, not with a score.
The key calculation is the energy efficiency class. 806 lumens divided by 5.9 watts gives 136.6 lumens per watt. For non-directional mains light sources the factor is 1.000, and the limit to class D is 135 lumens per watt. The lamp is therefore only 1.6 lumens per watt above the class limit, and class D is entered correctly. Colour temperature according to the register: 2700 Kelvin, colour rendering index 80.
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: Design
What the source states: Design: Classic A60 bulb shape with visible LED filament technology, clear glass bulb for a vintage look and 360° light distribution
Why this matters: This claim describes a product property, but does not yet answer whether it is practical for existing E27 lamp holders with a trailing-edge dimmer, without a documented dimmer list. What matters is the connection to the planned place of use.
Listing claim: Energy efficiency
What the source states: Energy efficiency: 5.9 W dimmable LED replaces 60 W incandescent lamp, 806 lm at 90 % energy saving and low-maintenance 15,000h rated lifetime
Why this matters: Such comparisons and saving rates come from the sales copy and name neither the reference device nor the calculation. You can only compare reliably through lumens and watts, and against the lamp that is actually to be replaced. The rated lifetime of 15,000 hours appears only in the listing title. In the register data we read, lumen maintenance (0.93 or 0.96) and survival rate 0.9 appear, but no hours figure. Without a manufacturer document, the figure remains a supplier claim. The replacement figure of 60 watts appears in the register, and under the regulation it refers to the luminous flux. 806 lumens correspond to the luminous flux of a classic 60-watt incandescent lamp. The brightness therefore matches the old lamp, but the figure says nothing about the light distribution of the filament shape.
Listing claim: Light quality
What the source states: Light quality: Warm white 2700 K light with Ra ≥ 80 colour rendering, continuously dimmable for a cosy atmosphere with authentic incandescent lamp design
Why this matters: The stated colour temperature describes the effect, not the brightness. In everyday use it matters whether fixed levels or a smooth range are offered and whether the setting is remembered. The register lists only the dimmable characteristic (yes or no). How far down the lamp dims and whether it stays steady while doing so depends on the dimmer and is not documented here.
Listing claim: Installation
What the source states: Installation: Standard E27 screw cap for direct replacement of incandescent lamps, compatible with standard dimmers without changes to the wiring
Why this matters: Dimmable only becomes a useful statement once the way of operating, the levels and possible compatibility are clarified. With a light bulb, the existing dimmer must also suit the LED. The listing names no dimmer list, no dimmer type and no minimum load. "Standard dimmer" is not a defined term. At only 5.9 watts, many older dimmers fall below their minimum load. Check your dimmer manufacturer's information on LED lamps before you buy several lamps.
Listing claim: Application
What the source states: Application: Perfect for stylish living spaces, boutique hotels and restaurants, ideal for chandeliers and pendant lights with elegant incandescent lamp design
Why this matters: This point should be checked against dimensions, instructions and the existing installation before buying. A listing can contain variants or shortened wording. This is a promotional statement. All that is documented is that it is a clear filament lamp in A60 shape with 2700 Kelvin and Ra 80. For chandeliers with an open lamp holder, the clear bulb shape is a visible design feature, and for shielded lights it brings no advantage.
Use in daily life
The lamp is not set up but screwed into an existing E27 lamp holder. It is 105 millimetres high and 60 millimetres wide. You need a free lamp holder with enough room in the shade. A separate socket or installation is not needed, as the lamp runs on the mains voltage of the light. Anyone who dims needs a compatible dimmer.
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.
The lamp is a general-lighting light bulb for dry indoor rooms. It is not a solution for rooms with special requirements: for the bathroom or outdoors the IP figure is missing, and for workplaces with high demands on colour rendering, Ra 80 is below what the Plus sister models with Ra 90 offer.
Strengths and limits of the assessment
What speaks for the model
- Product image, ASIN and listing data are clearly linked to one another.
- The form of the product can be matched to a specific lighting task: for existing E27 lamp holders with a trailing-edge dimmer, without a documented dimmer 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.
The purchase usually fails on the dimmer: a single 5.9-watt lamp is below the minimum load of many dimmers, so it flickers or does not switch cleanly. A second risk is mixing it up with the Plus line, because only that has Ra 90 in the register, while this lamp has only Ra 80. A third risk is the narrow lamp holder, into which a bulb 105 millimetres high does not fit.
What you should measure and check before buying
Read the model identifier on the lamp cap or the packaging and compare it with EPREL. Also check the minimum load and the dimmer type (trailing-edge or leading-edge) of your dimmer in the dimmer manufacturer's data sheet. In the light, measure the height of the shade or glass against the lamp height of 105 millimetres and the diameter of 60 millimetres.
- Clarify the task: Clarify whether you need a dimmable E27 lamp for an existing light or a complete light. These are two different product classes.
- Check cap and dimensions: Check E27 and room for a height of 105 millimetres and a diameter of 60 millimetres in the shade or glass.
- Check the dimmer: Look up the minimum load and type (trailing-edge or leading-edge) in your dimmer's data sheet. The listing names no dimmer list.
- Place the colour temperature: 2700 Kelvin is warm white, and Ra 80 is medium colour rendering. For higher demands, the register has sister models with Ra 90.
- Check the model identifier: Compare the identifier on the packaging with EPREL. There are several identically worded registrations with different 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
Three things count when fitting it. First, check that the cap is E27 and that the lamp fits in the shade. Second, check the dimmer's minimum load against 5.9 watts per lamp, and with several lamps add up the load. Third, switch off the power before changing the lamp and, after fitting, briefly run the lamp through all levels on the dimmer.
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 paperwork is in the box. For this item there are neither instructions nor a manufacturer page to download, and in the event of a complaint the retailer is the only point of contact. In a warranty claim, both are the only proof of which device you bought. Light bulbs and holders remain replaceable, so a later change of brightness or colour temperature is possible. This device is intended for indoor use only and 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 Classic A 60 Filament DIM, E27, 5.9 W, 806 lm, 2700 K makes sense if you are looking for a lamp for existing E27 lamp holders with a trailing-edge dimmer, without a documented dimmer list, have checked the dimensions at the intended place 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?
Common questions about the LED lamp
Is the lamp dimmable, and with which dimmer switch?
Yes, the EU register lists the lamp as dimmable. Which dimmers work is not stated in any document we read, and the listing names no dimmer list. With an older dimmer with a high minimum load, the lamp may flicker or not dim cleanly.
Which energy efficiency class does the lamp really have?
Class D. 806 lumens divided by 5.9 watts gives 136.6 lumens per watt, and the factor for a non-directional mains light source is 1.000. The limit to D is 135, so the lamp is only just above it.
How warm is the light and how good is the colour rendering?
The register gives a single value of 2700 Kelvin, that is warm white light, and a colour rendering index (Ra) of 80. That is decent but not outstanding colour rendering; the Plus sister models with Ra 90 render colours better in the register.
Will the lamp fit my lamp?
It has an E27 cap and, according to the register, a diameter of 60 millimetres at a height of 105 millimetres. In chandeliers and pendants with narrow shades or glass, check whether the lamp fits. The dimensions are usual for classic lamp holders, but in small shades it can be tight.
Is the stated rated lifetime of 15,000 hours correct?
We cannot confirm it. It appears in the listing title, and in the register fields we read only the lumen maintenance (0.93 or 0.96) and a survival rate of 0.9 appear. Treat the hours figure as a supplier claim.
Is the lamp also suitable for the bathroom or outdoors?
Neither the listing nor the register gives an IP rating for this. Without an IP figure, the lamp is documented only for dry indoor rooms. In damp rooms or outdoors, only a lamp with a suitable IP rating makes sense, into which you fit the light bulb.
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.
- EU product register EPREL, registration 2521384 (retrieved 2 November 2026), model identifier AC93227, entered by LEDVANCE GmbH: cap E27, 806 lumens at 5.9 watts in on-mode, a single colour temperature value of 2700 Kelvin, colour rendering index 80, dimmable, non-directional (NDLS), mains-operated (MLS), class D, lumen maintenance 0.96, survival rate 0.9, replacement figure 60 watts, height 105 millimetres, diameter 60 millimetres, market introduction April 2026.
- EU product register EPREL, registration 2178985 (retrieved 2 November 2026), model identifier AC70149: same key data (E27, 806 lumens, 5.9 watts, 2700 Kelvin, colour rendering index 80, dimmable, NDLS, MLS, class D, 105 by 60 millimetres), but lumen maintenance 0.93 and market introduction October 2024. The register thus lists at least two identically worded entries side by side with different lumen maintenance.
- EU product register EPREL, registration 2505754 (retrieved 2 November 2026), model identifier AC92562, sister model Superstar Plus: likewise 806 lumens at 5.9 watts and class D, but colour rendering index 90 instead of 80. The comparison shows that the advertised lamp shares luminous flux and power with the Plus line and differs mainly in colour rendering.
