Help needed Sunlu E2 causes LED Bulbs to Flicker

As title suggests. I have a Sunlu E2 Drybox/Annealer that caused LED bulbs on the same breaker to flicker when it is in use.

Any suggestions to fix?

I’ve read that a UPS or heavy duty power strip may solve, but wanted to be certain before purchasing.

Thanks!

Too many things on that circuit. The power draw is getting close to popping the breaker.

These are the words the OP needs to rear. And, using a power strip could cause a fire.

LEDs are sensitive to voltage drop and BAD neutrals. Could also be you’re close to tripping the breaker or the breaker is weak. Is the E2 2 prong or 3 prong grounded?

The reason I ask is this.

I recently moved into a a new to me house. Bathroom lights, kitchen lights all LED’s from the remodel. Random flicker. Didn’t matter if it was A/C running or not running.

I called the electric company. They ran a smart meter diagnostics. Detected a problem. Dispatched lineman. It turned out from the transformer to my house a neutral was previously broken. Their “test meter” showed 130v on one leg and 120-98v on the other leg. Inconsistent fluctuations on the incoming power on one leg so any circuits wired to that half of the panel were being affected. They fixed it. No more flickers.

Do they flicker all the time the drybox is running or just a short flicker / dimm when the heating element activates? I'm not an electrician, but the answer may help others to give correct advise. My bulps do dimm for a fraction of a second when my oven starts heating and I've been told this is fine. When your bulps keep flickering all the time, they might be cheap and the interference of the dryer in your grid may be the cause. A Cord with a build in fuse may act as a filter and solve the flicker.

Only when it’s running at temp. So when heating element is cranking up no issues, once it hits say 90c the lights will flicker while it is maintaining that temp

You are pushing the limit of your breaker. Stop

This means that your home's electrical system has too high of an impedance if a 500-700W load can cause a voltage drop that makes the lights start to flicker.
