Thank you very much for the CD/DVD idea! I see five clear differently-colored copies of my local compact florescent tube in my DVD's rainbow... can you confirm that I am interpreting that correctly as five spikes and virtually nothing in between those spikes?

My local incandescent lights are just a rainbow smear.

Oh, awesome, I can do it to my LCD screen too and clearly see three differently-colored reflections!

...

Forgive my geekout, but that's cool and I've never heard it before.

Why, yes. Yes I can confirm that. And I can tell you that noticing it about 25 years back, when I was doing photography professionally, saved me a metric crapload of money on special meters and so on -- but only after I had button-holed every single person I'd ever met to show them what I'd seen whether they cared or not. I truly understand the geek-out part.
