Ok, I found one on line that shows the ceiling fan.
Does it use the two spring metal tabs to hold the globes on?
If so, maybe you can bend them a little to increase the tension.
If they use the three screws like a residential model then mabe some lock-tite on the threads but then if you have to remove them........???????
It's so hard to be helpful here without a good closeup view.
Can you post some pictures of them?
