Desk lamps might be everywhere, but finding one like is surprisingly hard. YouTuber Darbin Orvar shows off one method to make your own with a few chunks of wood.
The general design here is just a few pieces of wood, but you can obviously customise that portion however you see fit. As for the actual LEDs, she uses copper backed strips, does a bit of soldering to connect the contacts together, then finishes it all of with a wireless button to turn it on.
You'll find the guide to make one for yourself over on YouTube.
