A60 LED — Compatibility, Simplicity, Long-Term Value
The A60 is the shape that most people picture when they think of a light bulb — the classic pear silhouette, 60mm at its widest, that fits into virtually every standard E27 fitting without any clearance or diameter concerns. That universality is its primary advantage. If you are replacing an old incandescent or halogen across multiple fittings in a home — table lamps, ceiling pendants, wall lights, floor lamps — this is the bulb that will work in all of them without needing to check dimensions first. At 4W, it draws a fraction of the energy of the 40W incandescent it replaces, and the frosted finish diffuses the LED source evenly, eliminating glare in open or semi-open fittings. The 2700–3000K range sits firmly in warm white territory — comfortable and residential, not clinical.
With a rated lifespan of 50 000 hours, this is a buy-once-and-forget bulb for most households. At 4 hours of daily use, that equates to over 34 years — meaning the energy savings over its lifetime far outweigh the upfront cost compared to replacing incandescents every year or two. It is a practical, no-compromise choice for anyone standardising their bulb stock across a home or rental property.

Common Questions
Is A60 the same as a standard light bulb?
+
Yes — A60 is the IEC designation for the classic pear-shaped bulb, 60mm in diameter, that has been the standard household bulb shape for over a century. It is the same shape as the incandescent bulbs most people grew up with, and it fits the vast majority of E27 lamp holders, pendants, table lamps, and ceiling fittings without any modification.
Can I use this to replace an old 40W incandescent directly?
+
Yes, as a direct drop-in replacement. This 4W LED produces a similar light output (250–499 lm) to a 40W incandescent while using 90% less energy. The E27 cap is identical, the A60 shape fits the same holders, and the 2700–3000K warm white tone closely matches the colour of a traditional incandescent. No wiring changes or adapters are needed.
Will this bulb work in an enclosed or airtight fitting?
+
LED bulbs generate less heat than incandescents, but enclosed fittings that trap heat can still shorten LED lifespan if the bulb is not rated for enclosed use. Check the product packaging or label for confirmation. If your fitting is fully sealed, look for a bulb explicitly rated for enclosed fixtures to avoid premature failure.
How much will I save on electricity compared to a 40W incandescent?
+
At 4W versus 40W, this bulb uses 90% less electricity for the same light output. Running it for 4 hours a day, the annual energy consumption is roughly 5.8 kWh, compared to 58 kWh for a 40W incandescent. At an average electricity rate of €0.40/kWh, that is a saving of around €21 per bulb per year — and the 50 000-hour lifespan means you avoid the cost of replacing incandescents every 1–2 years.
What is the difference between this A60 and the G80 globe bulb?
+
Both are frosted warm white LED bulbs with E27 caps and similar output, but the shape differs. The A60 is the classic pear shape (60mm wide) and fits virtually any standard fitting. The G80 is a larger, perfectly round globe (80mm wide) with a more distinctive silhouette — it suits fittings where the bulb shape is partially visible and contributes to the aesthetic. If in doubt, the A60 is the safer universal choice; the G80 is chosen when the rounded shape matters visually.
