(1) Minimum wire size requirements in section 6 of UL 588; the external wire must meet the requirements of UL588 standard, the wire size of the series lamp is 22AWG ; the parallel lamp is smaller than 20AWG.

(2) Sufficient strain relief requirements in sections 15, 71, 79, and SB15 of UL 588; do a power cord pull test according to UL588

(3) Overcurrent protection requirements in section 7 of UL 588. For overcurrent protection, the product needs to have a fuse!
