Bought E27 11W ES and then discovered it says not to be used with
dusk- to-dawn sensors.

Put lamp in anyway, and it works.

Why wouldn't it work and am I shortening the life of the lamp by using
it with a d2d?

I've got an exterior light outside with a 11w es lamp and a d2d sensor.
Been there 3 - 4 years, got it from Wickes.
