Wiring my basement. I've got 20 amp circuits using 12/2 wire. The rough
wiring passed the town's inspection. I need to wire two troffer lights.
Due to their location, I need to use the armor cable to wire the lights to a
junction box. Since I don't have the tools for the armor cable, I found a
pre-wired 6 ft whip at HD. The wire in the whip is 14/2.

Questions: Can I use this whip to connect the light to the 20 amp circuit at
a junction box? Are there such things as 20 amp light fixtures? I had to
use 20 amp plugs and switches, but I've never seen such a thing as a 20 amp
light fixture.

Thank you for your time.
