Unless the brand manufacturer has its own factory, it may get bulbs from several different sources. Also, tiny unavoidable variations in the materials and components of bulbs can cause them to fail at different times, even with similar application and use.

Does the shape of a light bulb matter?
It most certainly does. For one, there is the matter of aesthetics. Different shapes are used for different decorative applications. Round ("G" for globular) are often used in light fixtures in baths and dressing rooms as opposed to the most common "PS" or "pear shaped" light bulbs. Some light fixtures and portable lamps will only accept "T" (tubular) light bulbs such as picture and piano lamps. Certain shapes are determined by the electrical characteristics of the light bulb. Fluorescent light bulbs are tubular as a result although the tube may be wrapped or formed into different overall shapes, it is still a tube. Compact fluorescent light bulbs are simply fluorescent tubes that have been folded or wrapped into a compact shape. Light bulbs using reflectors have to be of a certain shape in order to properly reflect light in a certain direction and pattern.
