The Product Description and Details are both inaccurate. The description

electronic 60W 12v 'transformer' (300 to 450ms is more like it - about as
quick as a T12 tube in a Quickstart ballasted fitting) and their claims
for versatility in 'any room' and 'any situation' are far from the truth
unless we assume they had a particular 'idiot' customer in mind when they
wrote that "copy".

they always do. Sales material writers are also routinely clueless themselves.
