Moving forward with the pole idea, because the wiring for recessed lighting was impractical, the 1st prototype was made out of the 20ft pole for spherecam.  The mane revelation was how extending it to the ceiling allowed it to stay upright without drilling into the wall.  The same technique could allow shelves to go all the way up.  Only 12ft of it would be used.  Helical things were made out of wire for necessary storage & mounting the LEDs.  

Stock edison mounted LED lights would have been hard to mount  on the wire hooks, so attention turned back to some kind of flat LED panel with no power supply.  

The LED light was a 50W halogen replacement, stripped down to just the heat sink.  The bench supply in constant current mode would suffice.  It sucks 0.08A at 36V, dropping to 35V as it heats up.

It might be under powered, but didn't build up enough courage to probe the stock supply.  The stock supplies with the addition of fuses & enclosures are required.  The pole arrangement allows all the wiring to be on the floor.

Multiple 50W halogen replacements could be ganged on the pole, to create a 150W equivalent.  It would be a lot of wiring & a small fortune compared to a single edison mounted floodlight.

For 10 years, the lion kingdom lived with a cumbersome arch behind the computer monitor.  It originally wasn't painful.  It had a speaker on it, when the 6 channel amplifier still worked, but later became just storage & took up a lot of desperately needed desk space as the apartment filled up.  With the desk cleared of it & a view of the wall returned, it's like being back in that earlier time.   The desk is still filled with speakers which didn't exist in the earlier time, but the earlier time had much less horizontal space.
