Recommended procedure
1. Unplug and let cool. 2. Visually inspect accessible components. 3. Follow the manufacturer procedure (manual or official site). 4. If the fix requires disassembly, stop and contact customer support — EU warranty obliges.
Repair or replace?
If the fault persists after these checks and the appliance is no longer under warranty, compare the repair quote with the price of a new model.

Frequently asked questions
In Europe, any smart lighting bought new from an official reseller benefits from a legal conformity guarantee of at least two years (Directive (EU) 2019/771). This guarantee covers defects present at delivery, whenever they first manifest.
You can pick: European law puts the legal guarantee on the seller, not the manufacturer. In practice, a store return is usually faster, but the manufacturer can repair if the damage is out of warranty. Keep proof of purchase.
Our public methodology adds a Nura Score /10 penalty to any smart lighting whose recurring failures are documented in European user feedback. A model that breaks too often never tops our charts, brand notwithstanding.
Yes, within the limits of the European "right to repair": routine maintenance tasks (cleaning, gasket replacement, calibration) never void the legal warranty. Only irreversible hardware modifications can be a problem. For a smart lighting, any handling documented in the manufacturer's manual stays covered.
The directive imposes a two-year legal conformity guarantee, with a presumption of pre-existing defect during the first twelve months — the burden of proof is on the seller. For a smart lighting that breaks in that window, you're entitled to free repair or replacement, no strings attached on typical use.
