NSL vs UltraPro 24 Inch Hardwired Under Cabinet Light

Q: Is hardwiring DIY?

Hardwiring should be done by a licensed electrician. Safety note: under-cabinet lights connect to power by plug, batteries, or a hardwired connection to a household circuit. Use the power supply or cord that comes with the light, look for a UL or ETL mark, and do not exceed the rating on the label. Hardwired fixtures should be installed by a licensed electrician with the breaker off. Keep cords, batteries, and small parts away from young children, and follow the manual.
