Before buying a pendant, check four things that the shape alone cannot answer: how it gets power, whether the bulb can be replaced, whether the bulb and control can dim together, and how you will clean the fitting. Use the exact size and bulb you intend to buy when asking the seller.
Is this a plug-in or a ceiling-wired pendant?
Look for the product's installation method, not just a photograph of a cord. A plug-in fitting needs a suitable socket and an appropriate hanging arrangement. A ceiling-wired pendant requires a suitable electrical point and secure support. If you rent, check what changes your agreement and property manager permit before ordering. A swagged or off-centre shade also needs its own support plan.
The Layered Scandinavian Pendant Lamp is a ceiling-wired lamp for dry indoor spaces; plan installation with a qualified electrician.
It should therefore be considered only when that installation route suits your home. Ask a qualified electrician to assess the electrical point, ceiling support, position and local requirements. Do not assume a hardwired fitting can be made plug-in with a different cord.

Can I change the bulb later?
This WillaHaus lamp uses one replaceable E27 bulb, includes a bulb, and lists a maximum bulb power of 40 W.
That is different from a fitting with an integrated light source, where service options depend on the exact product. When comparing models, ask what part you can replace, how to access it, which bulb base and shape fit, the permitted power and voltage, and whether replacement parts or service information are available. Check the bulb and fitting instructions before buying a replacement.
For this lamp, the listed included bulb is 12 W with the 30 cm size and 15 W with the 40 cm and 50 cm sizes.
The supplied wattage is not a published lumen figure. If brightness or colour matters to you, request the exact included bulb's lumen and colour-temperature information.
Will my existing dimmer work?
Do not take “replaceable bulb” to mean “dimmable.” The bulb must be marked for dimming, and its maker should identify suitable dimmer types or models. Check the actual bulb, dimmer and any smart control together. An incompatible combination can behave poorly, including flicker or an uneven dimming range. If you already have a wall dimmer, note its model and ask the bulb maker or your electrician to confirm the combination before purchase.
The current listing for this lamp does not identify the included bulb as dimmable or provide a compatible-dimmer list. If dimming is essential, make that a specific pre-order question. A separately bought dimmable E27 bulb still needs to meet this fitting's size, electrical and power limits.
What should I check for cleaning?
Look at the shade from below and ask which surfaces collect dust, whether any part is removable for care, and how you can reach it safely after installation. A glass or layered shade may look simple in a product photograph yet be awkward above a wide table or near cooking vapour. Use the care instructions for the actual finish rather than assuming a general glass cleaner is suitable.
For the listed WillaHaus lamp, the care advice is to turn off power, dust gently with a soft dry cloth, and avoid wet cleaning, abrasives and pulling on the cable or shade.

Ask these before you order
- What is the exact power and mounting method for my chosen size?
- Which bulb base, shape, wattage and voltage are allowed, and is a bulb supplied?
- Is the supplied bulb dimmable? Which dimmer models have been checked with it?
- What is the finished hanging range, and can the installer achieve my intended position?
- Which surfaces can I clean, and what care method is approved for the finish?
