Light bulbs are constanly burning out

Frequently, when I switch light-switches on, I burn out light bulbs and at times a breaker jumps.

I am preparing to purchase new tube amps, (I currently have a ss amp). I am worried that these surges may cause damage to the new tube gear.

I live in a newly constructed building (4yrs old) which is shared with 5 other tenants. Throughout the building in the hallways and such, there are always burnt out bulbs. Bulbs last less than 6 month on average (incandescent, halogen and fluorescent)

This seems to occur randomly, last time was in the evening 8pm, whereas the time before it was at 4:45 am.

Need I be worried?
What can be done to solve the root of the problem?
What can be done to mitigate the risks? I already have a surge protector but I only have my Pre-amp, TT & TV plugged into it. I find the amp sounds better straight in the wall.

Nick_sr,

I would suggest you contact the landlord or building manager.

The problem could be a loose service entrance neutral conductor.

Have you ever noticed all of a sudden some lights get brighter at times while other go dim?

First call should be to an electrical contractor. The electrician will check line to neutral voltages at the main service. The electrician will determine if the problem is on the load side or line side of the meter/s. And if on the line side of the meter/s he will contact the utility company's service department.

Heres an interesting side story: A few years ago I replaced all the switches and wall plugs in the house because we changed the color to white. This place was built in 1979, so the originals were a bit different than what is available today. I did not buy the "pemium" ones at home depot because I needed so many. Ever since this, it has been very common to blow a light bulb upon flicking the switch if you do it too fast. I can even blow them on demand if I use the switch accordingly. Turning it on gently... no problem.

Did they use less than good quality bulbs to save on construction costs?

I have this issue in Austin. My voltage is about 127 volts. I buy 130v bulbs from Home Depot....

127V is too high... For residential customers the utility company is supposed to keep the voltage with-in (+ or -) 5%. 120V being the base line.

You should contact your utility company and ask them to check your incoming voltage. It may be a simple fix of moving the taps on their transformer to lower the voltage.
