Sounds like a waste of money IMO, I would just use them... color spectrum isn't extremely important...IMO stay away from the "Bright Effects" brand they sell at Lowes. I believe they are made by Feit for Lowes. I can not find any information on the Kelvin spectrum of the bulbs I bought. I dont trust them. I am going to replace all 12 with something I know is correct spectrum.
I was never happy with those bulbs when I used them. Used them on two grows and threw them away and got others and been happy ever since.
Iyou can clearly tell the difference between a veg bulb and a flower bulb .

Exactly... Not sure why dude would return them when all you have to do is turn it on and look...
Mainly because I could but aside from that I wanted to be sure of the spectrum as the bright white bulbs emit in the 4000k range and that wont work well for budding or veg. My eyes are not sensitive enough to distinguish between 3000k and 4000k but my plants will notice the difference. No harm, returned the bulbs and got bulbs that will work better for me. Now me and my plants are happy again.
I'll agree with your thinking. Having piece of mind on something is sometimes worth a few extra bucks.
