My bathroom has a light fixture with an arrow and a small hole on the other side. How can I open it? I don't want to damage it but I have tried some clockwise rotating.

I am not sure what the arrow indicates or what needs to be done with that hole on the other side.

Some photos:


tiny hole

Edit - tried counterclockwise too, not budging. I tried sticking a small screwdriver in the hole but there's nothing catching.

Edit - I believe it is an Asonia Round Brushed chrome effect Bathroom ceiling light from B&Q.

Edit - I went to a B&Q and quietly opened a box and took this photo of the manual.

Edit - success! It was counter-clockwise rotation and required a lot of force. The fixture that comes off is very heavy so be careful.

And if anyone is ever reading this, don't buy this dull, useless light fixture for your bathroom.

  • Just tried that now and it isn't budging.

  • Did you run into something inside the hole when you put the screwdriver in there? It could be a tab of some sort that you press in to release the cover.

    Possibly it is spring loaded and you need to pull down at the arrow, I know a lot of fixtures that downward force overcomes the spring tension and they come down but are retained by the springs (long spring wires).

    @FreeMan I went to my local B&Q and finally got a photo of the manual, edited my post!

1 Answer 1


According to step 5.3 of the manual you posted:


it appears that you push the cover up and turn to the right (clockwise) with 1.91kg of force (which is very specific, but doesn't strike me as much, but I've not seen force noted that way before) to install the cover*. That implies that to remove the cover, you rotate to the left (counter/anti-clockwise), then pull down.

This appears to be borne out by step 1.2 on the furthest right panel of the instructions.

If you'll note the section of the instructions I've highlighted:

enter image description here

There appears to be an angled slot that will pull the lamp cover up into place as it is turned and lower it away from a key on the base as it is removed. You may need to pull down very slightly as you turn it.

Also, note that in the instructions, there is an arrow on the base (screwed into the ceiling) that points down, and an arrow on the lamp cover that points up. In the instructions snippet I highlighted above, you'll note that if you turn the lamp cover too far that's indicated as being a bad thing. Your pictures of the fixture only show the arrow pointing down - it's possible that the previous installer turned the lamp cover too far and that the lamp cover is now somewhat jammed and will require greater force than was originally intended to remove. Have you looked around the lamp cover to see if there is a line-up arrow on it that isn't properly lined up?

It's also possible that the lamp cover has been in place for a while. Since you don't know how to remove it, I'm assuming that this is the first time you've changed a bulb in this fixture. If it's been there a while, it's possible that there's just been an accumulation of crud built up around the joint between the cover and the base and that it's just a bit sticky and will require a bit of extra force or some wiggling and gentle prying to remove. (Note - the fixture does look very clean, but that doesn't mean there isn't some small stuff that has settled into the joint line that's causing it to stick.)

In general, I think that it's just going to take more force to unscrew the cover than you've been applying.

  • If you're renting, have the landlord come take care of changing the light bulb - if he asks, indicate that it's stuck and you don't want to be responsible for breaking it.
  • If you own, keep applying force until something happens. Either it will come off and you'll know how hard you have to turn it, or it will break and you'll know that it probably wasn't installed properly. If it breaks, you already know where to go to buy a replacement! Either way, you'll end up with a working light bulb in the fixture. If you don't you'll have a non-working fixture that will annoy you for the rest of the time you live there.

* It just occurred to me - maybe the warning is that the lamp cover weighs 1.91Kg. That would be a very heavy cover and would most certainly warrant a warning as it looks like very light plastic that maybe weighs 100gm.

  • THANK YOU Mr. FreeMan. Yes. It required MORE force but once it was confirmed to go counter-clockwise I kept trying and it turned. And that 1.91 is the weight, the fixture that comes off is quite heavy. In case anyone is ever reading this, don't buy this crappy fixture.

  • (15 months later) I just had to open the fixture again. I couldn't remember how, only that I had posted on DIY. Thanks again.
