Think this is what you're looking for, next time just google "Kelvin chart" and it should show up in images. Hope this helps.

i was looking for the kelvin chart where it shows how usuable that type of light is for plants. on the chart it had graphed the different specs, 5000k etc. it showed that 5000k wasnt very usable to lights. a friend of mine has 4100k bulbs and we wanted to check the chart out.

I think I know what chart you are referring too, i've seen it as well, but don't remember where? But yes, your friends 4100k are far from optimal. Tell him 6500k for veg and 2700k for flower.
