I was recently excited to find an ”award winning” Ikea Riggad LED lamp on the ”take for free” shelf by the recycling area of my building. Plugged it in, did not work. Tried dismantling it with the help of these photos — https://www.youtube.com/watch?v=jhfZ-vwau8c https://www.youtube.com/watch?v=jhfZ-vwau8c — but some screw sockets seemed damaged and the screws would not come off. I could not see anything wrong with cables or soldering as far as I got, so I wonder if the LED or circuit board is the problem. Good design needs to consider sustainability, longevity and ease-of-maintenance in addition to how something works and looks.
