Something to do with UL. .
Here ya go...

UL doesn't issue warnings over "nothing". James has responded to the warning and tried to downplay the issue. UL could respond to James if they felt compelled to, but they haven't.
They had an issue with misuse of the UL label on one of their retrofit tubes. Not sure why CD has been poking at this here and there without providing any real info. The issue has been addressed and James continues to make decent fixtures. No reason to avoid them.
Here ya go...
On October 8, 2016, a fire erupted at the four-story Four Seasons Homeowners Association building, located in Beverly Hills, California. The fire and resulting smoke condition caused damage throughout the building and its cause is currently under investigation. The fire began in a James Industries' Direct Replacement Dual-Mode LED Tube (Model Number ZY-T8-18W1200 BIXX).
Another fire occurred on December 7, 2016 in Chelsea, Massachusetts at a large cold storage facility owned by State Garden, Inc. This fire again involved a James Industry dual-mode LED retrofit T8 tube.
The reason I mention this at all is because James is one of those companies that is shady about the figures that they report and this issue is just another example of their integrity.
I have no dog in this fight, just providing info for those that are considering what brands of products to buy.
