Alternatively, does anyone have a recommendation for a bottle dynamo?
The Velogical rim dynamo looks fun but it's only 1.5W.
Pretty sure 1.5w is fine, even if running rear light.
Nope. 2.4w is ok, 1.5 probably not.
IIRC the nominal output is 1.5W, but they do a couple of different versions (sport, special, touring) that produce more or less power at real-world speeds; I think they've been successfully used on the TCR &c.
