Also what is the real meaning behind a 741, I know it's closer to a cool white and it has something to do with K factor but, why is there a 3500k or some say 735 as high as 850, how do these associate with each other K and the three digit number??

in the 735, the 7 is 70-76 (or higher? the lamps I use are 76) on the CRI. Color Rendoring Index. the 35 is 3500 degrees K. So an 841 is 86 (or so) CRI with 4100 K color.

Thanks for explaining that. We had a lighting rep stop by for a lunch and learn. He seemed to give a pretty good overall explaination of general terminolgy of lamps.
When I asked this one question about 741 and 4100K he covered the K factor but couldn't explain their relationship.

Thanks
