I have 6 T-10 lamps that are buzzing as thay dim, need to find some that are 130v rated, sylvania's website is terrible and phillips only list 120v.

If these are four footers, the lamps themselves are running at a voltage much higher than the ballast supply voltage.

For buzzing at various dimmer settings, I'd explore the ballast and / or the dimmer ratings. IMO, the sound is from the ballast.

Why 130 volt rated?

Thanks for link, and I have had success with a higher rated lamp in reducing the buzzing during dimming

I'm glad you caught that first. I was saying "T-10's?" :-?
