I did a couple, this one is on brightfield lighting, where the subject isn't lit at all, just the background is lit. This doesn't eliminate reflections, because there are no reflections to eliminate, but from your viewpoint it's the same thing, because there are no reflections

And the other one is on darkfield lighting, which is basically the opposite

And this is the specular reflections one,

The story behind these very simple tutorials is that I had a 4000 sq ft studio with unlimited lighting equipment, but wanted to show what can be done in a tiny space with an absolute minimum of equipment.
As you will see from the tutorial, all that we do with brightfield lighting is to light the background, so that the light shines through the glass product, therefore there is nothing that can be reflected in the glass, because all of the light comes from behind. The edges of the glass will be clearly defined, because of refraction of the glass. Any engraving or similar will also be very clearly defined, and so of course will the bulb filament, in this case.
But, that isn't a complete answer because you may or may not want to show more than brightfield lighting can show.
Have the lamp switched on: You can have the lamp switched on, and this is easy provided that you're using powerful flash for the brightfield lighting. Control the brightness of the filament by choosing the camera shutter speed that shows it as you want it. If youi're having to do it without flash, simply take one shot with the bulb on and one without, and combine the two
Show the bits that won't be lit by the brightfield lighting: These are the bits that light can't pass through, e.g. any solid bits such as the lamp fitting. A pro photographer would normally use a focussing spotlight for this, they come with adjustable internal shutters that create the exact shape and size of light needed, but you can manage without one - simply take one shot with brightfield lighting and one without, and combine the two.
