So you agree this isn't the US company someone could easily confuse it
with.
I also question the listing for this being installed in a box the way
they describe. Knowing how the chinese abuse listing marks I might
even question the listing of the lamp replacement module and the lamp
holder they tossed in the box.
Are these at least halogram labels with control numbers?
**************** quoted text
UL marks come in many forms: it might be a label, or it may be
die-stamped, silk-screened or molded into a product. Whichever the
method of application, there are FOUR design elements that need to be
verified to make sure the UL listing is legit:
The UL trademark: the letters “UL” arranged diagonally (descending
left to right) within a circle, with a small ® symbol directly below
the U. If the “UL” letters are level with each other, side by side,
then you're looking at a phony symbol.
The word “listed” printed either below or beside the circle in all
capital letters: LISTED.
A 4-character alphanumeric control number, or a 4 to 6-digit issue
number. In the case of the issue number, it may or may not be preceded
by the phrase “Issue No.” as well as 1 or 2 letters.
A product identity phrase that concisely names what the product
is.
If any of these elements are missing or does not match the
configurations listed above, the UL mark is about as real as Santa
Claus, the Tooth Fairy and Snuffalupagus (sorry kids!

A common ploy is to use a listed part or two and imply that means the
whole product is listed. Lamps are famous for that. (Listed cord and
lamp holder but not the assembled lamp)
At any rate a suggestion in those instructions is far from a
requirement and I would defer to the manufacturer's instructions for
the wirenuts.
