Why aren't my lights lasting as long?
For starters, light bulbs that are handled roughly, jarred or shaken, and especially worst so if it happens while they're turned on, will get damaged at the filaments inside, which will start burning brighter than their rated lumens it will soon burn right out. Turning on the light frequently will also affect the life span of the light bulb, because every time the voltage is applied to the filament, it causes a sudden surge on the delicate filament and causes more wear and tear every time it goes on. Loose wires within the circuit which would make the connection intermittent would also have the same effect in the end. If that doesn't solve the problem, try using a better brand light bulb before blaming faulty wiring in the fixture or the circuit.
