7 Tips to Prevent Light Bulbs from Blowing Out

Light bulbs in some fixtures can blow out before their expected life span. Usually the source of the problem is easily detected and corrected.
The following are eight tips to maximize the lifespan of your light bulbs.

Tips to prevent light bulbs from blowing out:

  1.  Do not screw bulb in too tight.

    maximize the lifespan of your light bulbs.

  2.  Use better light bulbs.
  3.  Reduce the heat around the light fixture. Uncover or move the fixture. Using a bulb with a lower wattage may also work. Heat can blow a bulb.
  4.  Reduce the amount of vibrations around the light fixture or use a 130 volt light bulb. It is stronger and able to withstand more vibrating than other bulbs.
  5. Dimmers and timers blow out some fluorescent lights.
  6. Use an electrical meter to check that the electric current in the light fixture is a constant 120 volts. Electrical currents that are too high, low or fluctuate can blow out a light bulb. A difference of 5% between the voltage in the wires and the light bulb is enough to blow out a light bulb.If there is a steady current, use bulbs that match the voltage of your reading.
  7. If the flow is too low or is not constant, inspect the blown out bulb for indentations. If there are indentations then there is probably a loose connector in the fixture where the bulb is screwed into.

To tighten the connectors on the light fixture:

  1. 1. Unplug the lamp or turn the electricity off in the room off the fixture.
  2. If necessary unscrew the light fixture.
  3. Find loose any connectors, wires and gaps in the connectors.
  4.  Tighten the loose connectors and wires by tightening the connecting screws.
  5.  Screw the light fixture back into place.

How to Repair and Remove Conduit for Electric Wires

remove conduitsConduits for electric wires hold and protect electrical wires. To avoid damage to conduits and wires it is important to install conduits away from sources of heat and water. In event that conduits are damaged it is important to repair them promptly to avoid damage to wiring. Damaged conduits may be a sign of damaged wiring.

There are different types of electric conduits. Match the replacement electric conduit with the existing conduit. Ensure that the conduit is wide enough to hold and rethread all the wires.

Tools: Electric conduit, conduit connectors/fittings, pipe cutter/conduit saw, wrench, pliers and/or screwdriver, threading tool, electric tape, electric fish tape, electric pulling lubricant.

To uninstall conduits for electric Wires

1. Shut off the electricity flow.

2. Disconnect the wires as close to the damage as possible. This will reduce the amount of rethreading wires through the conduit later on.

3. Pull one end of the wires out of the conduit.
Note: In many situations it will be helpful to attach fishing tape to the wires and wrap electrical tape around them before the removal of conduit wires. You will need to separate the fishing tape from wires later on to get rid of conduits that were damaged and to install the new sections of conduit.

4. Unscrew or use pliers to remove conduit supports.

5. If the damaged area is part of a small section of conduit, use a wrench to unscrew the electrical conduit fittings on both ends of the damage.


If there is a large section of conduit, use a pipe cutter or conduit saw to cut out the damaged section of conduit. Cut a couple of inches extra into the undamaged parts of the conduit.
Get rid of conduit pipes that were damaged.

To install the new conduit for electric wires

6. Measure the size of conduit needed to replace the removed conduit.

7. Cut a piece of conduit piping with a pipe cutter or conduit saw according to your measurements.

8. If the wires in the original conduit are accessible, pull them out of the conduit opening.

9. Place the wire through the new conduit. If needed, detach the wires form the electric fishing tape.

10. If you did not push the electric fishing tape through the conduit (as recommended in step 3), push electric fishing tape through the conduit starting where the wires were disconnected.

11. Wrap the uninsulated end of the wires around the electric fishing tape head and wrap electric tape around them.

12. Put electric pulling lubricant on the electric tape that covers the head of the electric fishing tape.

13. With a wrench, screw electric conduit connectors over your cut piece of conduit and over the existing conduit on both sides. Make sure it is tight.

14. Screw the conduit supports back where they were.

15. Pull the wire though the conduit using a threading tool to feed the wires into the conduit and by carefully pulling on the fishing tape on the other end.

16. Reconnect the wires to there original place.

17. Turn the electricity back on.
