I believe they don't have a legal obligation to cover bulbs under warranty, but have done so in your case as a goodwill gesture. That's certainly the case over here with a UK light manufacturer I deal with - their terms state that batteries and bulbs are no covered under warranty, but that they will "look favourably" on claims within a few month of purchase. (And they did offer to replace my battery after just under a year).
Normal bulb failure is not covered since it is a wear and tear item. But that's not what my example addressed.
I was discussing abnormal bulb failure, i.e., infant mortality. That is covered under the guarantee that "SureFire warrants our illumination tools, edged weapons, and pen products to be free from defects in workmanship and materials, including any LEDs housed within, for the lifetime of the original owner." If a bulb burns out on first use fresh out of the package, I'd say the buyer has a very strong case that the product was not free from defect and thus is covered under warranty.
