Spectro will be accurate on all light sources.
Colorimeter (a good one) will be more accurate at the lower light output of 10 and 20%
However the colorimeter relies on adjustment tables which are not perfect and in some cases off a good bit.
So you profile the colorimeter with the spectro and you get a more accurate meter..
What is profiling? The spectro is set up on your display, the software will do the hard part. You will display the appropriate white, Red, Blue and Green pattern and readings are taken by with the spectro. Then you colorimeter is put in the same spot and the same readings are taken. The software figures out the differences between the 2 (spectro being the reference meter and assumed correct) and makes an offset table that is then used from that point on with the colorimeter on the current display. This offset is only accurate for the display you make it on.
I thought I would be happy with the C6 Colorimeter, it is a nice meter and fairly accurate on some light sources and will give you a way better image in the end than out of box.. BUT once you get it and get your set calibrated, you start to wonder.. is it really accurate? I now have an i1pro to profile it with and know it is as good as I can get for what I can afford.
Please note: The i1pro will work just fine as the one and only meter and can be found used for less than the C6 or D3. If I didn't have a projector and was only going to be doing direct view sets for myself, I would just go with the a used i1pro for DIY. This is my hind sight, but as it is, I do have a projector so now that I have both I am content with the C6/i1pro and Calman.
Hope that help... it's an investment in tools or gear for a hobby just like a new set of golf clubs would be..
