Why don't all light bulbs use premium parts?

Asked by RedDeerGuy1 (10405points) 1 month ago

Like the famous firehall lightbulb that is on constantly for 100 or more years? Sorry that I can’t find a link I’m on my smartphone. What is keeping it from burning out?

One reason that lightbulb has lasted is that it hasn’t been switched on and off. That makes it hard on the lightbulb. And, the bulb was handblown glass And premium parts cost a lot more.

People don’t want to put out $50 for a lightbulb, even if it will last 20 years. I’d rather spend $2.50 a year for twenty years than spend $50 now. And the lightbulb maker would rather have a stream of $2.50 income going forward than a one time profitable year and no sales for 20 years.

It also glows at a much lower light intensity.

If light bulbs last too long, they can’t sell more light bulbs. They are deliberately designed to have a limited life.

Manufacturing cost. Build a cheaper product, have a lower market price, sell more product. If product fails to deliver a certain lifespan, no problem: More product sold.

This is the first I have heard of this light bulb. I found a Wikipedia article on it. The article says the bulb is currently only drawing 4 watts of energy. It does not say for how long this has been the case.

Against the claim that planned obsolescence is the reason light bulbs don’t last very long is the recent introduction of longer lasting LED light bulbs.
