luminelation 

The feeling of elation experienced when an unattainable/partnered crush suddenly seems much less desirable thanks to the introduction of less-flattering room lighting.

I spent the entire night sat across from the most beautiful girl I'd ever seen, crushed that she already had a boyfriend.

At the end of the night, the fluorescent lights came on, revealing a thick black strip of girl-moustache spanning her entire lip...oh, the luminelation!

lumenflation 

The tendency of Chinese manufacturers of bicycle lights and flashlights to claim an artificially high light output. This has necessitated the creation of a new measurement unit, the chilumen or "Chinese Lumen," which has a variable conversion factor to actual lumens.

"I just bought a 10,000 lumen flashlight for $7.99 including shipping from Shenzhen China."
"You're a victim of lumenflation. That flashlight is 10,000 chilumens, not 10,000 lumens."
