wait- there is someone else in the world that does not like LED's? Look james- I am not alone! The greenish hue you speak of has to do with the phosphor coating on the LED lens itself. all high power LED's come from a very bright blue LED probably starting around 6-8000k color temp. They then coat that LED with a yellow phosphor or stain to create a warm white color. the problem again is getting it just right, and just right over a really long period of time. but we all know yellow and blue make green. The other element of this equation is how long and to what degree of degredation happens over a 25-50000 hour life of that yellow phosphor. everyone hopes it does very well, in spite of the problems shown in my testing and most other folks from fixtures 3-4 years back. but I find the color thing was so bad back then when LED's first started coming around, that when it got close folks were happy enough. I have to say for my eyes 2700k to me is not a warm orange but a whitish yellow with no green. I would say a 5000 hour mr-16 at 11-11.3 volts is just about perfect. The Volt LED's I am currently testing are probably closer to 3200k, or a a tradtiional halogen at 12-12.5 volts.
