You're in the dark because the light bulb in the room has died and you're all out of spares. You head over to the local home or grocery store to get a replacement and you are face with an endless variety of shapes, sizes, wattage, lumens, incandescent, fluorescent, neon, and LED. The interesting thing is the prices are anywhere from $1.00 to $150.00 depending on the product's proximity to the front of the store and whether it is WiFi enabled and has multiple colors.
I do not remember when and if it's still enacted by incandescent bulbs were being taken out of circulation. And at the time of inflection the prices of the alternatives was crazy high. Now as things start to settle I have come to accept the fact that I will convert to LED. But there is one serious issue.
Look closely to the bottom left of the packaging above. "Last 22+ years" and "Lasts 10 years". There are 2 problems with this claim. [a] there is no way to guarantee the lifetime and in fact there is no such guarantee. [b] How would you know if it did not last 22 years? In the earlier model we accepted that the cheap price of the bulb meant that a replacement was $0.50 or less away. It was also reasonable to have a few dozen spares in storage. And in the case of an electrical storm replacing the bulbs would only cost $100 or less depending on the number of bulbs. My home requires 55 bulbs of different sizes, watts, and decor. At $5.00 a bulb that would cost about $300.
Still, the issue is that bulb lifetime is meaningless if there are no guarantees. So now what?
