If the maximum run length of the tape is exceeded, the copper busses will be overloaded and 
will heat up more than they are supposed to.  In the long run, this will defeat the heat-sinking 
function and so fatigue the mounted components.  In the short run, the heat will raise the 
impedance of the copper and contribute to operating problems.  Heat stressed-copper can 
increase in impedance permanently.  As the copper is heat-corrupted, the added impedance 
increases the heat generated and the copper is damaged further, which increases the heat, 
which increases the impedance, which increases the heat, which increases the impedance,… 
 
Exceeding tape run length with single color LED tape can result in the following problems: 

1.  Excessive heat from the overloaded busses on the tape 
2.  Heat based component failure 
3.  Loss of output 
4.  Difference in brightness between the beginning and the end of the Tape 
5.  Permanent damage of the tape 

 
Exceeding Tape run length with RGB LED tape can result in the following problems:  

6.  Excessive heat from the overloaded busses on the tape 
7.  Heat based component failure 
8.  Loss of output 
9.  Difference in brightness between the beginning and the end of the Tape 

a.  Interaction between the R,G and B Channels, resulting in flickering or strobing at 

dimmed levels 

10. Permanent damage of the tape
