I am wondering how to open this lighting fixture to be able to replace the MR-16 bulb. The fixture seems smooth with no openings or bolts. It is a bi-pin halogen MR16 bulb. The is a indented ring in front of a glass plate protecting the bulb. Everything seems really air tight with no moving parts. A real mind boggler! thank you. Melvin
I've seen a few fixtures like that. See that tabbed ring around the outside of the face of the bulb? Try compressing it with needle-nose pliers right where the missing tooth is. It should pull out and then you will be able to pull the bulb out.
Installation is the reverse of removal. :) It should just snap in after the pins of the bulb are seated.
Assuming these are push-in, two pin bulbs, you don't need to take it apart.
Use a small suction cup to pull the lamp out from its face.
Use a small wooden stick stuck between the louvers to push the bulb out from behind.
Use a plastic (non conductive) screwdriver stuck under the base of the lamp, through the louvers, to pry it away from the fixture.
Maybe the louvered part of the fixture unscrews from the domed part of each bulb holder. That would make it easier.
