Has anyone tried these? Combos of red&blue LEDs in a square panel.
Supposed to be as good as HID systems with less electricity. Amazon
has them via some other vendor. I'm tempted to try them for the
seedlings I should get back from flasking in May.

Which systems are you looking at?
I looked at them back before I had a wife and step kids, and
I just couldn't see the extra cost of the fixtures paying for
the electricity.

however, since that time more vendors have been trying to deploy more
high intensity LED fixtures for more tasks.
I just haven't had time to look at them again :-).

I'm trying to remember the terminology my sister in law's husband uses,
but I think he'd call that an assembly. What you would kludge together
to keep from electrocuting yourself would be a fixture :-).

I've seen the panels of 225 LEDs before.

looks interesting, but the lack of spelling on the website is appalling.

The question I couldn't find an answer to is the demensions. Is this a
3-inch square, 6-inch square, foot square or a yard square or somewhere
in between? One would need to know the size before deciding the value.

Extrapolating from the power plug picture on
http://www.superled.net/ledgrowlights.html
I'm guessing that device is about 5"x5"

Looking at http://www.creelighting.com/LR6.htm
I'm thinking that the other products don't have sufficient thermal handling.

However, i think I hit the cool stuff here...

Well, I decided to try one since I couldn't find anyone who did and
found it didn't work. I will test it first against fluorescent lights
and maybe try some marigold seeds, the kind that bloom in 30 days or
so, those real tiny ones. If that works, the tomato plants will be
next, and when I put those out in the garden, my flasks should be
here. If the marigolds and tomatos work, then I'll put some of the
babies under the LED lights and some under the fluorescent ones. I'll
post my results.

It did not like a fire burning lamp ballasts, hydroponics to other plants. It is not hot, just warm. You will not experience unsightly brown burned when they accidentally touch the LED. This is the most common other witnesses who have become very hot.
