IKEA now has them for like $8. Pop in a $1-2 LED bulb, and Bob's your uncle.

Of course, my encounter with facilities involved convincing them I'd not brought in a halogen lamp (remember those, in torchiere lamps?) that was going to burn the place to the ground. (Back then, it was a compact fluorescent. A technology I've come to despise for various reasons.)

For something more compact and portable, I might look for a lightweight sconce that I could hang on one of those 3M removable hooks. Or, if they don't bother you, a very compact/portable desk lamp.

P.S. That place, I might have been better off if it HAD burned to the ground.

Hear hear; I work remotely and check-in physically maybe twice a month when delegates come down to our satellite office. I find artificial lighting absolutely grating. Working from home it's a rarity for me to turn on a light until as late as dusk.

Anyway, there were a few corner offices I eventually set up a little system with: if that office owner didn't want their bulbs replaced, to put a sticky note covering the light switch. I'd come through, check for a sticky "okay, no new bulbs for this manager" and move along. Was a pretty good system until our facilities manager politely asked me to stop and change the bulbs anyway.
