Pendant light choice would usually be for a specific purpose so if you will move things around I would have a rethink. It may be possible to have a pendant with a long lead & hooks for the cord that would allow you to move it within a reasonable distance of the connection point. Maybe some general lighting might work better e.g. or two or three directional spotlights along edges or the ridge line & on dimmers if possible. Subtle strip lighting at the top of the grey wall & the addition of a feature decorative wall hanging & potted plants would look nice too.

I love industrial too it's raw.. clean lines..our place used to be a shop..terrace out the front then they built an extension out the back to house the printers..hence the high ceilings..we visited Japan just before renovating this place thus the Japan render..pendants were made by one of our client to say thank you..court yard etc

It might be worth while to consider the rest of the space also. Your breakfast bar/kitchen is located quiet closely to your dining table so depending on your kitchen space (apologies, I can't see too much of your kitchen from the photo) you might want to think about the overall style you want to achieve for you entire open plan space, and select pendants that would work for both your kitchen and dining. This is a project I worked on recently that shows how two different types of pendants can work harmoniously in the one space that is most similar to your kitchen and dining set up. Keep us posted on what you decide!

I would remove the globe, then with hot soapy water wash the entire outside of glass pendant and if your hand can fit, the inside as well. Maybe even a quick spray of a cleaning product like Ajax spray and wipe to get the grease off the outside, before wiping over the entire glass pendant. Obviously you will need a ladder to stand on to reach pendant safely. Make sure the glass is room temperature, not hot.
