I need to source a large quantity(1k-2k to start) of cheap SMT(about
1mmx1mm) RGB LED's max avg current of about 25mA or so. I'm not paying a
buck a piece ;/ I found some everlights on mouser for about 25c each for
quantities over 100 but now they have almost doubled in price(up to 43c) in
about 6 months.

Of course, I'm asking if anyone knows of a source. (accidently hit the send
button)

I have not seen RGB so small (1mmx1mm). We are using bigger one
(2mmx2mm, 100mA) for roughly 50c. I will ask if they can find smaller
one.

I have some RGB modules with 256 tri-color LEDs (768 total) installed
on it, along with 6 controller ICs and heavy, metal heat sinking. The
whole thing sold for about $60 each, I think. So, including a lot of
useful drive circuitry and mechanicals work, about 24 cents each. They
were sold for panels that would be 20 wide and maybe 15 or 16 high, so
they were probably purchased in around $20k buys, at least. Spacing
was 3-5mm and the tiny LEDs occupied perhaps 1mm square in the middle
of each. Memory serving.

An SMT tri-color without the circuitry and mechanicals should, I'd
expect, be less. I'm curious how things have changed, though, so I'll
be watching the thread. It's been a few years.

I got some RGB LEDs in strips. They are in groups of 3 mounted on 3"
FPC strips for $1 each. So, each LEDs should cost less then 33c, if
the 150ohm resistors and FPC are free. They runs off 12V and much
easier to deal with than SMD LEDs directly.
