While we're on the subject, where is a good source for RGB LEDS?

I got mine here:
http://www.lsdiodes.com/shop/index.php?main_page=product_info&cPath=5&products_id=62

A buck-ten each.

R:3000 mcd typical (20ma)
G:5500  "     "
B:5500  "     "

These are common cathode; common anodes are available if you search enough.

The Chinese distributor mentioned a few months ago is much cheaper *if*
you buy a lot.  And they had both common-anode and common-cathode, if I
remember.

YMMV

I don't know if this is the Chinese distributor you're referring to but I
buy my LEDs from the "Chi Wing LED product shop" on ebay.

They charge $39 for 50 RGB LEDs (it doesn't say if it's common-anode or
cathode, but iirc the ones I have from them are common-anode).

If you are doing imaging, you won't want to use the clear ones. They
project 3 color spots. The diffused ones mix the color very well.
