Greetings

I have this fancy ceiling tube light fitting and I cannot figure out how to replace the tubes.

It has two ends which somewhat come away but not enough to remove the tubes. There is wiring both sides.

I'm not sure how much more pressure I can apply before something breaks. There are holes on the sides of either end which look like they're for accessing a screw or a latch but I don't see either of those things.

Not sure how I would get the tubes back up and fitted if I even got one or both the ends off anyway. It's daunting.

I don't have a make and model so I cannot find a guide online.

Please put me out of my misery and let me know how to tackle this beast!

Thanks!
