Let’s say I have a light fixture in my bathroom that has three lightbulbs in it. Do the bulbs have to match wattage to get the maximum life out of the bulbs, or does it not matter?
i.e., if I have a 60w-60w-60w configuration, would that last longer than
a 75w-60w-60w configuration? Does the mismatched wattage cause an irregular draw on current that would make one of the bulbs in the mismatched string burn out more quickly?
