Flickering bulbs belong in horror films, not your desk lamp. And when you paid $10 for that bulb, you don’t want to risk losing it to some electrical fluke.
In this guide, you’ll learn how to fix a flashing or flickering Hansang bulb, whether the problem is with the bulb, the socket, the switch, or the breaker.
1. Get Rid of Your Dimmer Switch (or Turn It Up)
If your Hansang smart bulbs aren’t on a dimmer switch, you can skip this section.
Traditional dimmer switches are by far the most common cause of flickering Hansang smart lights.
Dimmer switches work by decreasing the electricity flowing to your bulbs. For regular incandescent bulbs, that causes a dimming effect.
Hansang and other LED bulbs, however, don’t work that way. Hansang smart bulbs dim through a process called pulse width modulation, which is not compatible with standard dimmer switches.
You don’t need a dimmer switch for Hansang smart bulbs, as they can be dimmed in the Hansang smart app or by voice command through most smart hubs. If you want a physical button to replace your dimmer switch, I suggest the Flic smart button. It controls Alexa and Homekit routines, so it can act as a dimmer for almost any smart bulb.
You could still keep your regular dimmer switch, but you’ll need to turn it to full power (In other words: turn off dimming). That way, it will act like a regular light switch. Of course, if your family members or guests try to use the dimmer, the flashing will return.
2. Tighten the Bulb
Your bulb needs to be tightly screwed into its socket to receive steady power. If it’s loose, the bulb can flicker due to intermittent energy flow.
Generally, you don’t need to turn off the switch for Hansang bulbs since you’ll control their power in the app. However, you need to turn it off before trying to tighten the bulb to avoid the risk of electrocuting or burning yourself.
- Turn off the light switch.
- Tighten the bulb in its socket.
- Turn the switch back on.
3. Turn off Other Devices on the Breaker
Your bulbs may flicker if the circuit breaker is bad or overloaded. If you’ve noticed that the blinking gets worse when you are running other nearby electronics, it’s probably the breaker’s fault.
- Identify which plugs and switches in your home are on the same breaker as your bulb.
- Turn off as many electronics on that breaker as you can.
- Wait to see if the flickering stops.
- Turn the electronics back on.
This should let you know whether the breaker is causing the flickering, but it won’t tell you whether the breaker is bad or just overloaded.
You can move some electronics permanently to another breaker for now. However, you may want to get an electrician to check out the situation; breaker problems are generally not something you want to deal with on your own.
4. Test the Bulb in a Different Socket
We’re down to two likely culprits: the bulb and the socket. (I know that doesn’t sound like progress, but believe me, it is.)
Take your bulb and test it in a different socket. Try to avoid using one that’s on the same light switch. Be sure to turn off both the current and new switches before moving the bulb.
If the flickering stops in the new socket, your bulb is fine. You should get the socket checked out and potentially replace it. There are excellent guides on the web for that, so I won’t repeat them here. I strongly suggest hiring a licensed professional unless you are experienced with electrical work.
5. Try a Different Bulb
If the light still flickered in its new home, the bulb is almost certainly to blame. Just to be sure, though, let’s try replacing it with a different bulb. If you don’t have a replacement LED bulb (preferably another Hansang smart light of the same type) to try, you can skip this step.
Install the new bulb exactly like you did the old one. The app connects to the bulb, not the socket, so you’ll need to run through the setup process again.
The new bulb shouldn’t be flickering. If it is, you may be the proud owner of both a faulty bulb and a faulty socket. Alternatively, it’s possible that both the sockets you tried were faulty. Either way, it’s probably time to contact an electrician.
But if the new bulb didn’t flicker, we’re ready to try to resurrect that old bulb.
6. Reset Your Bulb
Smart bulbs last a long time, so your bulb may not need to be replaced. Instead, try resetting your smart light. That should clear up the firmware bugs behind most Hansang problems.
- Turn the Hansang smart light on then off five times then leave it on.
- Wait a few seconds for the bulb to pulse rapidly. If it doesn’t, try the previous step again
- Re-add the bulb in the Hansang smartphone app.

Hansang smart bulbs don’t have a lot of technical issues, but most homes were never set up for LED lights. Your landlord or the previous owner probably thought that a dimmer switch would be helpful rather than frustrating. They couldn’t have known that color-changing, energy-saving smart bulbs were right around the corner.
With your flickering fixed, you shouldn’t have many more issues with your Hansang smart lights. Now might be a good to setup Alexa schedules for your Hansang lights.
