I don't think the darkness of the thc strip has a thing to do with how much thc you have in your urine. I posted a pic yesterday where I tested a new bottle of QF and the thc line was real faint just like my own urine is when I'm clean.
The directions also say that the brightness of the line is not important. A line is a line no matter how faint.
