Lifespan for a typical incandescent home use bulb is around 1,000 hours, but usually ranges between 700 and 2000 hours. Heat, vibration, mechanical shock, over voltage conditions, and on/off cycles are all a factor in bulb life. If you leave your lamp on 24/7, that is about 700 hours in a typical month. So if you’re getting a couple of months or more out of your bulbs, that’s pretty good indeed.
There are bulbs for high heat applications (oven bulbs) and/or or applications that experience vibration or mechanical shock (fan bulbs), but they are more expensive by a multiple. Most people will not need these special application bulbs, and so we’ve found that the inexpensive bulbs we sell are the best value for your salt lamp. Now that you understand the issues, you can experiment with more costly bulbs for different applications if you feel that you would benefit from that extra expense.
The incandescent bulbs used in Himalayan salt lamps are meant to be in a stationary position. If they are moved suddenly or are exposed to vibration, they can blow or have a diminished life Consider what happens to a flashlight bulb when the flashlight is dropped? (many now use LED bulbs to combat this type of failure)
High humidity can also cause bulbs to blow. This happens by creating corrosion on the contacts, which then creates higher resistance in the circuit, causing them to blow or wear out prematurely. All of this is also a factor in your dimmer or on/off cord circuits and bulb holder that is part of the power supply cord.
Power spikes or surges through your circuits in your home or office occur constantly. Your electric items are manufactured to tolerate this to some degree. But spikes mean problems for any electric item, and the cords & bulbs used in Himalayan salt lamps are sensitive to this as well.
If you have bulbs popping or blowing regularly, here are some things to take into consideration:
- The bulb is not quite screwed in firmly enough to touch both contacts. This causes more resistance which can wear the bulb & cord out prematurely.
- There is condensation on the bulb or electrics of the dimmer causing them to corrode and create higher resistance.
- The bulb is touching the inside surface of the lamp, or after a bulb has been changed, the cord and bulb has been pushed too far to the top of lamp and is touching the salt. This creates hot spots that concentrate too much heat on the bulb.
- The lamp is moved while or after the lamp has been on long enough to heat it.
- There is a large current drawing appliance on the same circuit that is turned on/off and there is a momentary power spike or fluctuation that reaches the bulb and dimmer cord electric components.
- There is excessive ‘micro vibration’ nearby ie: too close to a TV, refrigerators, etc.
- If the lamp has been turned off and sweated, salt may have leaked onto the bulb which will cause it to blow.
