Light bulbs going out


I have 3 lights outside that i am replacing the bulbs maybe every other week. It's not the same light each time, it a different one abd it is getting expensive. Any idea what this could be? The tag on the fixture says no more than 100W, so I have gone with 100W. Would a lower wattage bulb solve this problem or would a short in the wires somewhere cause this?

Thanks,

Tim

Might be a loose neutral...do this lights dim or get brighter when loads are started?

No. I just get home, flip the switch and notice a light is out? Would the loose netral be at the panel or at any of the lights since they are on the same circuit?

Extremely cold weather?
An incandescent bulb's filament starts out with a very low resistance, which will drop as ambient temperature drops.
In colder weather, the inrush current on a 100W lamp may increase enough to cause premature burn-out.

Try replacing the bulbs with the new CCFL screw-in bulbs. These will take some time to come on in the cold weather, but I think they will last a lot longer.

Another factor could be the brand of light bulb. There is a lot of crap coming across the ocean from... you know where, and I am sure they don't make them as good as the old GE or Westinghouse (although, to be honest, I'm not sure even those guys don't have their bulbs made in the same place as the cheap ones)

there is a difference is quality.

one person mentioned "vibration". That is a big cause in some situations. A quality lamp will help. A rough service lamp will help even more.

Thanks. I use Westinghouse 100W bulbs. I just looked on the box and these are a "Value" bulb. They make a "Preferred" and a "Superior". They are $3.50 each and and I have tried an ACE Hardware bulb ($7) each, but will give a name brand higher end bulb a shot.

The other thing, are these fixtures on all night and day? you would be surprised how fast they seem to be going because someone forgets to turn them off.

See if your bulb says 120 or 130 volts if you only have the 120 volt bulb you should try the 130 volt bulb.

Three lights doing that is kinda odd.. But if the bulbs are all the same quality it may be the culprit.

As previously stated I would switch at least one bulb up to a quality long life or rough service bulb. Rough service has a shorter life but a heavier filament.

Swapping out the switch for a dimmer may help. It allows the light to come on slower rather than a "full on"

I have two outside photo lights that come on dim before going to bright and the bulbs last several years easily.

the problem with the CFL, is the light bulbs go in black lantern style fixture, so the bulb needs to be a candle looking style. Do they make those in CFL's?

What would 120v vs 130v accomplish? Don't know much about that so just curious.

I solve dthe problem. I went to Lowe's and they told me to flip the breaker and pull up the tab/spring that the bulb screws into. Did that abd it works like a charm

A loose connection causing more heat than a tungsten filament? Not very plausible.
Maybe the on/off intermittent contact, temp. cycling the filament.
Wait and see if the fix continues to work.
