Kitchen light - high pitch frequency noise

[ronald911]

Hmm not just a starter but also take out the ballast, LED tubes work best when they go straight into 220v. Its unlikely the LEDs are making the noise

Think replacing the ballast to one with a different voltage solve it?

Don't use any ballast, they not supposed to be used with LED

By the sound of things, I think the noise is coming from that black box.

Note, it makes that noise, with (both Fluorescent and LED) and without bulbs... It didn't make that noise prior to installation of the new inverter.

You can disconnect black box , just a power factor correction capacitor.
White part can also be bypassed if using led tubes, bit more complicated than doing the cap .

Maybe you got tinnitus...

More likely to have Hyperacusis....

Yes it is most probably the ballast causing the noise most inverters do not give a pure sine wave but closer to a square wave this can even cause some transformer and ballasts to heat up, maybe find out where you purchased the led tubes if they have a diagram how the tubes can be wireed directly without the ballast.

Btw, is the white part the ballast and the black part the capacitor?

I am a bit hesitant to comment,as there may be other stuff available, I'm in CT; however I have converted a number of old Fl tube setups to run Led tubes of different makes: Osram and others.
In all cases the fitting was gutted of all its old parts including the starter, (the +- 20mm Dia x 35 mm long starter).

TheTubes were supplied with the tubes' fuse (looks like a starter) was put in where the starter was. The supplier told me this and warning stickers came with to say Led tubes only....to be stuck on the modified to Led fittings.

Led (Fl style ) tube fittings have nothing inside just wires and a connector block.
