How to remove this ceiling lamp cover held together with three metal latches
As usual, it's easy when you know how.
The bolts attached to the metal rim of the light fixture (the part that's tight to the ceiling) are not the adjustable part.
Instead, the other part of them, the decorative metal clips that the glass bowl sits in are fairly flexible.
Here's how you remove the glass shade:
Cupping the glass shade in one hand, gently pry (with your finger) ONE of the decorative clips it sits in up toward the ceiling away from the glass bowl.
From here, you should be able to angle the glass bowl downward and out.
To put the glass bowl back in place once you've changed the bulb, pull back one of the decorative metal clips toward the ceiling and angle the shade back in,
letting the decorative clip gently flip back to hold the glass in place.
Good luck and be careful with electricity!
Always turn off the power.
