Potential fire hazard - do not use in salt lamps with dimmers

These lamps have a very short lifespan. When they fail, they sometimes trip the switch. I recently changed the lightbulb in my salt lamp which has a dimmer on the cord. I later noticed a burning smell and realized it was coming from the dimmer. The triac in the dimmer has blown due to overcurrent. This is because the bulb I just replaced had a section of filament that shorted and allowed the bulb to draw too much current. When I measured the DC resistance, this faulty bulb was 80 ohms. An unused lightbulb in the same packaging had a resistance of 100 ohms. Of course, many salt lamps have been recalled due to defective dimmer switches, and this is definitely one of them. The outages were probably caused by using those cheap lightbulbs! No fuse, circuit without overload protection combined with cheap lamps with a high failure rate is the perfect recipe. But everything is made in China, and that's the true cost of cheap labor and outsourced quality. I will fix the dimmer circuit on this lamp, maybe add a fuse. I'm also going to replace all those cheap bulbs with LEDs that should protect the other dimmers. In the attached photo, pay attention to the main filament on the left near the base. The excess reaches and touches the support wire (appears black) holding the other section of thread. This will short out the filament bypassing the other section and allow the lamp to draw more than 15 watts. Bad quality control.

Pros
  • Economical
Cons
  • Large and bulky
