Mine buzz.

Traditional ballast designs act much like a transformer, have you ever walked past a transformer on a power poll and heard that buzzing noise? That's eddy currents in the windings causing the buzzing noise.

[weedahoe]

Mine buzz when just starting up.

 

[MonsoonMike]

Yes, that is normal. It's part of the transformer inside that causes it. Kind of cool!

 

[LPGHemi]

Yep..............mine does it like Weed's.
After a short while, it goes away.
