What is the method by UL certification for terminating each LED strip?

I would like the Centric Daylight product at 5000K and might need more than 1 or 2 power supplies.

The sconce, for example, has a 17 & 3/4-inch existing PC board with 4000K LEDs currently. Which I will remove. The spine of the wall sconce is 18". I will ground the sconce structure to comply with NEC 2020 Code.

As this assembly will be only 1/24th the power needed, a 96W power supply seems way over spec. And I will need to power two independent sconces and therefore power supplies. 

If I cut the strip at 17" or 18", what do need to power these strips, please? What is the method, by UL certification, for terminating each strip- please?

Though we are unable to provide detailed assistance for retrofitting or adjusting third-party fixtures, we can confirm that an 18” length of our LED strip light would require 7.75 watts and 337.5 mA. 

Given that our own power supplies might be excessive for these installations, you may be able to acquire a lower-output 24V power supply for the fixtures. 

As extra low-voltage Class 2 components, we are not aware of any specific termination requirements for our LED strips once they are cut to length. For further recommendations or regulations regarding electrical code compliance, we would recommend reaching out to your local authorities (AHJ). 

We recommend using a pair of sharp scissors to achieve a clean cut, and taking care to ensure that loose wires and other objects do not come in contact with the LED strips.

Would you direct me to where these devices are identified by the IEC 61140 Class definitions, please? (I anticipate these are PELV, not SELV, and Class 1, not Class 0.)

As to the product- I was hoping to identify if the UL listing(s) cited from the sales page had an NRTL solution, not just components 

The 2020 NEC, which I plan to adhere to, is the most current version. Municipalities many times lag over two Handbook versions. As is the case with my installation site's jurisdiction.  

If these are only, say, the 2010 version of NEC applicable- why not just say so? As to the NEC- power supplies are to be Class 2 compliant. 12V DC drivers must be 60W and under. Or 24V drivers must be 96W and under. Power supplies that comply with the Class 2 regulation are always marked or labeled as so.

We have just confirmed that the product in question is categorized as ‘Class I’ per IEC 61140 definitions. We can also confirm that this product is rated to separate extra-low voltage (SELV), as can be noted in the attached product label below. Further, the product is marked as a Class 2 LED Power Supply and conforms to UL 1310 and UL 8750. 

We have also attached a link to the UL file listing for this power supply product below, for your reference.
