Some customers claim that there is something wrong with the lightbulb because when you turn on the flashlight, it flickers and then goes out. This is NOT a lamp problem! Some flashlights that originally came with incandescent bulbs have a cut-off circuit when the battery is low to avoid destroying the battery (nickel-cadmium batteries). I know of two examples: Milwaukee 49-24-0155 and 49-24-0165. When you turn it on, it powers the bulb, but when the power is low, it turns it off. If you have a lightbulb that draws very little current (like these LEDs), the circuit will think the battery is low and turn it off. Hence the flash. I bypassed the low battery circuit (I'm an alien) and now it works great with this LED bulb. That. Very convenient for camping.
