I dont think I would leave it on unsupervised. I would be worried about it overheating.

The voltage in my house right now is 112v, I doubt running an incandescent bulb at a lower voltage would overheat it.

But I'm replacing it with an LED bulb anyway. I just noticed the odd voltage rating as I was replacing it.

Oh please, that’s “suggested”. I’m sure it can take more

Spoken like an electrician. The bulb is rated for up to 130v. That means that is intended for 120v systems. Single phase power systems fluctuate voltage all over the US. The power at my runs at around 124v while my buddy across town is usually at 121v.

Fun fact, running a light bulb at a lower voltage then designed will produce less light light, sure. But it'll also substantially increase its life span.

If memory serves, the world's longest left on light bulb (at some fire house in the USA) is fed with just enough volts to make the filament glow.

I wonder if this bulb was meant for sales all throughout North America. I once read that while household electricity in the US and Canada is 110v - 120v, in Mexico it is 127v so this bulb would’ve worked fine anywhere in North America.

Centennial Light

In 1976, the fire department moved to Fire Station #6 with the bulb; the bulb socket's cord was severed for fear that unscrewing the bulb could damage it. It was deprived of electricity for only 22 minutes during the transfer, which was made in a specially designed box and with full firetruck escort. An electrician was on hand to install the bulb into the new fire station's emergency generator.
