The correct answer to this question is A, The same. The reason why they would have the same brightness is that the bulbs are connected to the same power source, which is the Geneon. Being that they are connected to the same source, the bulb will have the same brightness based on that source.

For example, if two phones were connected to a speaker, the sound would be based on the speaker itself and not the capacities that the devices have. Even if these bulbs could go brighter, it will be based on what the power source is set to.
