They're fine, but any life span numbers I assume are inflated so shop accordingly. Small variance in numbers you can ignore but be wary if its dramatically shorter life that another model.
I used some Hella H3 bulbs on my brothers R6 Streetfighter over the summer. They seemed to last longer than the Sylvania basic ones that were dim and burnt out quickly, as well as the EVO brand ones I found on amazon.
The evo and the Hella were both exactly the same brightness with a photography light meter, but the hella gave much better night visibility due to the standard color. The evo did have a crazy green/blue light that looked sweet so I used it for the running light.
These are not the bulbs you need but you can use to compare I guess.
Walmart : Sylvania 55w H3, I probably had issues due to wattage
