Hello POOL PROFESSIONALS!!!

I would like to know about the cord size of Hayward swimming pool light model LPCUS11030,LPCUS11050,LPCUS11100. Are they different from one another if we consider the voltage drop? E.g. 30ft = 8.0 sq.mm THHN; 50ft= 14 sq.mm THHN; 100ft = 22 sq.mm THHN

If no, what's their cord size?

Also, have you experienced installing Hayward LFGUY1000 niche? Is it easy to install? Do you have any problem/issue with it?

 

Thanks in advance.
