Steps:

  1. Disconnect the device from the wall.
  2. Unscrew the four screws hidden behind the rubber feet.
  3. Make sure to keep the rubber feet and screws somewhere safe.
  4. Use a screwdriver as a lever to release the top cover. Unscrew the metal shield below.
  5. The metal shield is a perfect place to keep all the screws you are going to meet on your way down.
  6. Confidently tear the case apart at the top and remove the transparent plastic ring.
  7. This may require some force.
  8. Take the front and back panel apart. This may require some more force.
  9. The parts are fairly durable, but take care anyway.
  10. Uncrew the white cover and remove it.
  11. Unscrew the black cover. This way you can access the lamp more easily.
  12. You will find an open power supply below the black cover. Do not touch anything down here.
  13. Unscrew the four small screws holding down the two white brackets which hold the bulb in place.
  14. Carefully remove some of the soft glue in the bulb's socket. This way you will have a better time removing the white brackets.
  15. Gently take the interjecting parts of the white brackets apart. You can now remove the brackets (get a screwdriver in between if you need to).
  16. Push back the black hooks holding the bulb in place and pull out the bulb. Do not pull on the glass bits, but on the base of the bulb.
  17. The bulb has four contact pins at the bottom stuck to a connector plate underneath. They are only jammed into the holes there, but quite strongly.
  18. If you can not pull the bulb out like this, stick a screwdriver between the bulb's base and the connector plate next to one pin at a time and gently crank them apart. It will yield at some point.
  19. Put in your replacement bulb and check for mechanical compatibility.
  20. If the bulb's base is a bit too tall, you can use a file to make the black hooks fit or just clamp the bulb down using the white brackets (which will then look slightly crooked, but seems fine to me).
  21. Put the black and the white cover back on, reconnect the lamp to the wall and see if the bulb will turn on.
