I can't find the ul listing E236810 on their website, can I use these lights under KITCHEN cabinets according to ul/ nec

What lights? :confused:

The lights that have the ul listing . E236810 , They are the ones the home depot sells

I'm afraid the UL listing means nothing. That does not identify the lights.

If they are under cabinet lights then you are using them as intended.

Can you provide a link to the lights?
