Has anyone seen such a beast (non DIY)? I thought it would be a cool gizmo to have on the desk at work.
I have the EE skills to build the electronic side, but lack the craftsman skills to build a luminaire that looked reasonably professional.

What’s the volts/amps PoE can do? You can probably find a lamp to match and then rewire a socket on to it. Maybe even a control thing if you get wild and have control over network, IoT and all that.
Or if it is easier, an inline control so it just passes power on to the lamp with no major reworking of the electrics and the control done from a more dedicated external source.
All the gear at work is poe+, 57 volts roughly 25 watts available. But that voltage is not on the line, the device has to ask for it specifically.
Retrofitting a poe extractor into a lamp is something I will look into.
Quick search turned up something close:

That would be handy to have inside the datacenter! I found this on their website as well:

You have tried a normal LED desk / home lamp which has an external power supply and will fit the energy needs of your poe. Then replace the AC-DC power supply with the poe splitter and power the lamp.
Just instead of changing AC to DC from the power supply, you will supply DC 12VDC 1A / 9VDC 1A / 5VDC 2A directly from the splitter to the led lamp. The task is to find a lamp that will be current compatible.

5V could probably just be fed into a USB lamp.

Personally, I would not play with a usb lamp or poe.
I have a 10w LED lamp at home which is powered by AC such a power supply …
Match the appropriate POE splitter and you have an ordinary LED lamp, and it’s better than dedicated poe because it’s better choice in lamps.

Same.
LED stuff usually is 12V (because that works nicely with the ~3V drop on white LEDs.
Or just 240/120V from the grid and LED bulb.
Situation stands as there’s more poe ports than electric outlets. As there’s nothing off the shelf, doubling up on multi-outlet strips is the solution I guess.
12v would have to come from the grid too… So same solution.

PoE Splitter + LED lamp. Best imho solution. You can always use a normal AC lamp someday without spending $ again, which you won’t do with a dedicated poe lamp.
In addition, the quality of light / brightness adjustment range / position on the desk will be in favor of the normal lamp and not the poe.
But the decision is yours.
