When you need a lamp that delivers 4000 K neutral white light, not the yellow-warm glow, the LEDVANCE E27 13 W/4000 K and related models step in. These are standard E27 base lamps, rated around 13 W (equivalent to ~100 W incandescent) with luminous flux ~1521 lm, CRI ≥ 80, and lifetime up to ~15 000 h.
For facility-managers, this means consistent tone across corridor and office zones; neutral white is less “yellow” than warm white around 2700–3000 K and gives a cleaner look without being stark daylight.
In many installations — back-of-house, utility spaces, storage rooms — you don’t need dimming. The non-dimmable versions of the LEDVANCE E27 4000 K line (for example the 4.9 W/4000 K filament variant) use the standard E27 socket, fit decorative or compact luminaires and avoid compatibility issues with dimmers.
From the installer’s point of view: fewer failures, less flicker, straightforward swap-in for older lamps. For example: replace older P45 or GLS lamps with 7.5 W or 5.5 W LEDVANCE units and cut energy use while keeping the same fixture.
When the lamp is visible — pendant, globe, filament form-factor — the LEDVANCE Value Filament A100 11 W/4000 K model and similar decorative E27 bulbs deliver both form and function. These lamps use filament LED design for visible aesthetic, are 4000 K neutral white (less warm than traditional decorative lamps) and match glass fixtures where look-and-feel matters.
Installers note: because the base and shape stay familiar (E27), retrofitting is trivial — same cap, similar geometry, fewer changes to the luminaires.
From a procurement budget standpoint, the LEDVANCE energy-efficient E27 bulbs category is compelling: for example the 13 W/4000 K unit replacing ~100 W incandescent uses ~87% less power.
For large-scale lighting—offices, retail banks, storage areas—bulk replacement with these lamps means reduced energy bills, predictable maintenance intervals and fewer lamp changes over time.
Ordering “E27 LED” but mixing warm white (~2700 K) with neutral white (~4000 K) in the same zone — result: visible color mismatch. Or specifying a non-dimmable lamp in a dimmable circuit — flicker risk. Using generic “energy-efficient” without verifying lifetime and lumen maintenance — may lead to earlier replacements.
For procurement managers and installation contractors, the LEDVANCE E27 LED lamps 4000 K range offers a strong, brand-backed solution. We provide:
If you’re specifying lighting for retrofit programmes, office fit-outs or decorative lighting projects and you need the E27 4000 K category, choosing the LEDVANCE line helps standardise parts, simplify maintenance and deliver consistent lighting quality.
