LED Christmas Lights -any good green ones out there?

[(remove X from email when]

I have three strings of LED Christmas lights from a company called
Holiday Creations (holidaycreations.com) They sell Fiber Optic
Design's Foreverbright line. Here is a summary of what I found:

Blue: Very high output -a true blue colour
Red: Very Intense -a true red colour

Green- not a "true green" but rather more of a lime colour and
probably about 1/4 the light output of the others maybe even less
since the eye is even more sensitive to this range

The lamps only draw on 1/2 the a.c. cycle and this causes noticeable
flicker. I placed a full-wave rectifier in front of the green set and
it pretty well doubled the output and reduced the flicker
considerable- but still not near the red or blue in brightness. This
trick worked for red as well but not blue as 1/2 the string of blue
was wired in reverse polarity so 1/2 did not light up.

Now I know true green and high intensity are out there since I have
some as discretes and they were not any more expensive than blues so
what gives?

Now I am wondering if anyone has come across a high intensity green
set. I need the mini types not the pine cone or ball shaped lamp
shapes. If you have some, please forward me the make and model.

More green please! (or is this so we can trash ours and upgrade in
2005!)

Some but not all "Forever Bright" strings had true green LEDs a year
ago. Try Brookstone. Some models that I saw in their online catalog last
year even had purple LED bulbs.
The "basic model" that I got at Walgreens last year has the dimmer,
"olive green" "pea soup green" very yellowish green LEDs.
Last year I also got a red-orange-yellow-green LED string of a different
brand at Target, and its green LEDs were also the very yellowish green and
dimmer than the other colors.
