How do I remove a recessed LED casing/housing?
I have recessed LEDs in my house, but the ones in the bathroom have a special casing (pictured) - presumably to keep moisture out. I've tried twisting and pulling reasonably hard to remove it to change the bulb, but it doesn't want to shift! I can't remove the bulb first as the casing is obscuring the fittings. Is there something obvious I'm missing?
