Most people at the major stores do not know anything about the bulbs, you are right about that! You can check what bulbs they have and then do some research on the net to try and find the spectrums. The nm spectrum is far more important to the plants then the K temp is, but it's important to find bulbs that look good to you as well... You can find good name brand plant bulbs even in Canada for less than 50 bucks. The Geisman bulbs are great and can be had for 20 - 30 bucks a pop from a place like J&L aquatics in Vancouver for example.
