There are multiple Things out there for R-Pi's that use an Ikea JANSJÖ LED lamp
The desk lamps used to cost $13 at Ikea -
Only $10 for white
The clamp version was $12 -
$10 for white or black
The gripe is that they are no longer available from Ikea, and other online retailers charge double (and more)
$30 +/- $3 -- https://www.amazon.com/Ikea-Jansjo-Flexible-Desk-Light/dp/B0071IFNRO
$25 +/- $3 -- https://www.amazon.com/IKEA-JANSJÖ-Clamp-spotlight-white/dp/9178917174
All that is left are the JANSJÖ LED USB lamps for $6 ( priced at $5 in the same archive.org 2018 catalog )
These only throw 10 lumens vs 88 lumens from the other two
Also, I found out by printing out a Jansjo thing that the USB version is considerably SMALLER than the plug-in versions.
I am not going to waste time and energy asking Ikea to bring them back. Retailers never listen to the customers.
The apparent replacement seems to be NÄVLINGE
Desk lamp for $17
Spring Clamp for $15
Bolt Clamp for $18
I just found a nearby eBay-er that had a clamp JANSJÖ for $22/free shipping.
I bought it so I can compare it to a NÄVLINGE and because it is one of the lowest prices for a plug-in JANSJÖ I have seen recently.
I will post more details as I get them.
Feel free to contribute to the discussion.
