My smart bulbs take several seconds to turn on after the command
Home Nura guide — category: Smart Lighting
Diagnosis
This symptom is common and usually harmless. In most cases, a targeted clean or a small change in how you use the device fixes it in under 10 minutes.
Recommended steps
Unplug the device and let it cool down, then clean the affected part with warm water and mild dish soap (never use an abrasive sponge on a non-stick coating). Put it back together, plug it in and run a short empty cycle to make sure it works.
Repair or replace?
If the problem persists after these checks and the appliance is no longer under warranty, compare the repair estimate with the cost of a new model.

Frequently asked questions
Usually, yes, if the failure shows up during the warranty period and isn't caused by misuse. A product in the Smart Lighting category bought new from an authorized retailer normally comes with a manufacturer's warranty: check its length in the manual or on the brand's website. Consumer protection rules also vary by province and territory, so keep your proof of purchase.
If you're still within the store's return window, a return or exchange is usually the fastest fix. After that, the manufacturer's warranty takes over: its customer support can arrange a repair or a replacement. Even outside the warranty, the manufacturer can often repair the device for a fee. Either way, keep your proof of purchase.
Our public methodology lowers the Nura Score /10 of any model in the Smart Lighting category whose recurring failures are documented in owner reviews. A model that breaks down too often never tops our rankings, whatever the brand.
Generally, yes. Routine maintenance, such as cleaning, replacing a gasket or recalibrating, is part of normal use and doesn't usually affect your warranty. Irreversible changes to the hardware are what can cause problems. For a product in the Smart Lighting category, stick to the steps described in the manufacturer's manual and read the warranty terms before going any further.
When a product fails in its first few months of normal use, the cause is usually a manufacturing defect. Contact the seller or the manufacturer with your proof of purchase and a description of the symptom: for a model in the Smart Lighting category that is still under warranty, this is the typical case for a free repair or replacement. Warranty terms vary by brand, so read yours.
