CRI = Color Rendering Index. It's basically a measure of how accurately the light reproduces an objects color. It doesn't mean a whole lot for growing outside of photographing your grow. I believe CRI=100 means the light remains faithful to an objects natural color while lower numbers mean the color will be skewed.
What you're probably looking for is the color temperature in degrees Kelvin. A typical HPS bulb is in the 2100K range which is good for flowering and less good for vegging.

What lamp are you referring to anyhow?
Like I said, a run of the mill HPS bulb is about 2100K. I'd bet 50 to 1 whatever HPS lamp you're looking at (16000L so that must be a 150w?) is about 2100K just like nearly all of these HPSs: http://www.e-conolight.com/Product/EProducts.asp?ProductFamilyID=22
If it's not 2100K it's a specialty HPS bulb.

i know but i cant use it due to the size of area my grow ops in, and besides in only growing small amounts at a time (1-3 small plants)
and plus heat problems is another reason.

Thanks for the info <3
So do you think 150m3 per hour intake fan and a cool tube will handle it , and if so what distance from tops should i put it ? Cous my box is 105 cm tall :/
What should i go for 250w hps or 400w in my space .
Atm only with fan working the temp is 19C and RH is 50%
Its a basement so i think the temp will stay constant trough the summer.
My space is 60cm deep 105cm high and 90cm wide.
Atm i'm waiting for my seedling to pop , have 6 seeds of Hashberry wich acording to mandala is very heat resistant plant it's also most of it indica so i thing i can keep it low at high.
