How to view image in accurate lighting with CRI bulb

Hi - I know this is not an actual photoshop question but I need to match colors accurately in photoshop. I know that color is dependent on lighting. I would like to see a paint color swatch in a consistent daylighting that I can match by eye in photoshop.

From what I have read the light bulb needs to be a CRI of close to 100 and a color temperature of 5000-6000.

1) am I on the right track to viewing an accurate color indoors?
2) where can I find a bulb like this?

thanks!
 
I'm riding a train at the moment, so I can't respond, but I know something about this and will get back to you late tonight or early tmmrw.

I will say this: You are *absolutely* on the right track to be concerned about this.

You didn't say what type of bulb you want.
Bulb type and physical size matters.
My local supply house stocks the Philips TL90, F32T8/TL950, a 4 foot fluorescent T8 lamp.

An electrical supply house may have or could order these lamps for you.
 
I thought I could use a small screw in bulb or a cfl. I only need to look at paint swatches under this light but I need them to look as real as possible for outdoor light.

What would you recommend? Would an electrical supply house understand what I need or is the internet better?

I am just learning about this stuff.

Hiya, Puppy - Sorry for the delay in getting back to you, but this is the absolute worst time of year for me. I'm responsible for reviewing a huge number of projects, and I'm finishing one phase of a major photographic job in which my client is coming up on a deadline.

Anyway, the best I can do at the moment is point you towards some previous discussions that hopefully are relevant to your question:

WOW - this is getting complicated. I read the links a few times although written by pro's and a bit technical for me.

I phoned Solux, they have a 4,700k 98 cri MR-16 bulb. They don't have a 5500k. Sounds great but the problem is that I have to use their lamp which is expensive. I went to Lowes and they have MR-16 fixtures but snap in, not 2 prong.

I just found an adapter for the MR-16 that converts it to standard Edison base. I hope this is ok to use for it can solve a big problem.
