I have mounted ceiling light dome that can't twist, pull, push or open in order to change light bulb. It looks like this:
I have tried twisting it counter-clockwise,clockwise with bear hands, with latex glows, tried pulling it down and nothing moves it one bit. I have noticed 3 small holes on the upper side that are visible on the second picture, but because of there position and size it is impossible to reach screws (if there are any) with screwdriver.
I don't even know what model is this light-fixture, because I moved in new apartment recently.
