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!)

High intensity red LEDs are cheao, so they use 'em. High intensity
blues have been made in large quantities because they're needed for
white LEDs. So the prices for blues has fallen rapidly, and even the
mediocre blues will work okay for x,as lights. But the greens don't
have the demand for large quantities that reds and blues have. So
they're not as cheap, and the ones that are are just log grade ones.
There's a great demand for the green that's used in stop signals, but
that's more of an aqua color. So with green it's just kinda take
whatever you can get.

How do they diffuse the LED's light? The ones I've seen recently use a
light bulb sized and shaped plastic casting over the LED, with lots of
dimples in it to diffuse the light. I was seriously unimpressed with
the brightmess of these. They were about $10 for a smaller string, $15
for the longer.

The leds are molded into a form of solid transparent epoxy so there is
really no cover perse and yes the surfaces are dimpled which act to
diffuse the light further. The solid material acts as a light guide
and produces a more even distribution of light ie the whole piece
appears to glow.

Personally I am not in favour of this approach as it pretty well
eliminates the intense point of light that one sees with the
traditional clear incandescents which is a more dazzling effect.

I am sure preferences differ but I would like to see the option of
both types offered. Are they afraid that an intense point of light may
put the consumers vision at risk? This may be valid for some high
intensity leds but I am sure thay could tone it down enough if need
be.
