How to figure out the Kalvin Temp of a CFL lightbulb?

Okay, so i have like a million CFL's kickin around my place but they all seam to be of the same type. Most say Nomad on them and list the wattage and ect, but they do not say the Kalvin temperature and i would like to have 6400-6500k for in my veg. I would like to avoid going out to buy new ones as they are a bit pricey and im really fuckin broke. Is their anyway that i could find out the kalvin temp maybe by comparison or a site online that list brands and specs? Does it really even matter that much to have it of the right spectrum? I found one lightbulb that listed the kavins on the bulb and it was 2700k FML!
i could use that for flowering... if only i wernt growing mother and wont be growing buds inside. Can anyone please hep me?

Also, all the lightbulbs are 13 watt, i only found 3 light sockets and have put them in a amplifier converted into a growbox, the size of a large computer. would 3, 13watt lightbulbs be enough?

Anyone please?

Any CFL lights that don't say its Color Temp (kelvin) (k), its prob 3000k or 2700k more than likely. If its a 5000k or above, it will say either Cool Blue on the pack or Daylight (CFL), and these are a bit higher (in price) than the 2700k CFLs. The 2700k CFLs are everywhere, so just look for the word Daylight on the pack. Hope this helps!

It does, but do i really need 6400-6500k? what will happen if i use 2700k?

If you use the 2700k you will get more stretch to your plants. 6400k is recommended in veg because it will keep the plants stockier with tighter nodes. Also when you plug the bulbs in 3000k and under will have more of a redish orange glow vs the 6400k which will seem blueish clear.

okay thanks alot
