Common solutions

Most questions have a fast answer. Filter the list to find your issue in seconds. Can't find it? Our team will personally see it through.

Still need help?
First, check the bulb is fully seated and the wall switch and fuse/breaker are on. Try the fixture in a different socket, or a known-good bulb in the fixture, to isolate whether it's the bulb or the fitting. If it still won't light, email info@dizentech.com with your order number and we'll arrange a fix or replacement.
Flickering is usually a dimmer-compatibility issue. Make sure any dimmer is rated for LED loads, and that the total wattage is within the dimmer's range. Loose wiring can also cause it — if you're comfortable, switch off the power and check connections, otherwise use a qualified electrician. Tell us your product model and we'll confirm the right compatible dimmer.
Most smart bulbs connect on a 2.4 GHz network, not 5 GHz — check your phone is on the 2.4 GHz band during setup. Keep the bulb within range of the router, power-cycle it to enter pairing mode (it usually blinks), and allow the app location/Bluetooth permissions it asks for. If pairing still fails, share the device model and app you're using and we'll walk you through it step by step.
Once your order ships, we'll confirm the dispatch and any tracking details by email. For an update on lead times or the status of a current order, message us with your order reference through the Quick Enquiry form and we'll respond promptly.
