re: Remember when they told us LED bulbs would last 20 years?

First or close to first generation. Newer ones are designed to fail. They had to have a reason for people to adapt in the roll out phase. Now they are that are readily available. Lamp manufacturers have been in the business of intentionally designing products with a shorter than necessary life expectancy since the beginning of the lamp industry...it is well known and well documented.

Just about all lamp types last longer when used continuously than when they are being turned on and off regularly. Starting and stopping is detrimental to all electrical and electronic components.

Another dirty little secret is they lose their brilliance very fast...no matter how good a driver they have all LEDs degrade very fast...so that 100 watt lamp equivalent that is supposed to last 5 years and use the same amount of energy as a 30 watt lamp will only be 100 watt equivalent for a few hours...they start to degrade immediately. Depending on the quality of the LEDs and the driver they may lose up to half the light in 6-8 months...most sold in big box stores are designed to do so. All lamps do this, none at the speed that LEDs do it. It is noticeable from the time you turn them on...they will all be noticeably dimmer when they have been on a while. Once turned off and back on they will be slightly dimmer than they were when they were turned on last time.

I put some 60w equivalent ones in my living room ceiling fan last week and you need sunglasses in there now with the light on.

We have some Phillips L prize bulbs from 2012 that are still bright and going strong. This is the bulb that won the competition the DOE held for a led bulb. They were about $60 each here. Flew through Denver and ended up walking through a Lowe’s during the layover. SUBSIDIZED price was $5 each. Filled a cheap duffel bag and brought it as a carry on.

LED headlights are a big reason I drive with sunglasses at dusk..most driving with their brights.

Bedside table lamp bulbs probably only ones that track that usage rate in my house.

Even if incandescent bulbs were free I would not use them. A 60 watt bulb used 2 hours per day costs $6.50/year to power (at 15 cents/kwh). If you have any bulbs that stay on all day or all night it would cost $40/year to run. And that is per bulb. Or $80/year if on 24/7. I don't think most people quite appreciate how much money LED bulbs save, probably because most of us just replaced them a handful at a time over the years. They save about 80%.
If you switch back to incandescent bulbs throughout your whole house right now, your power bill will be in the neighborhood of $100/month higher. I have 8 exterior flood lights that stay on all night every night. They were 120W bulbs that were costing about $600/year in electricity. I put in some "expensive" ($10/bulb) LEDs that are just as bright but only draw 14 watts. That $600/year now only costs about $100/year in electricity. I'm saving damn near $50/month just on exterior lighting.
Soooo I should turn off my floodlights during the day?
They've been on for 3+ years I think

I use brand name outdoor LED lights on a timer so they are on 10-12 hrs a day. They last about 2 -3 years. That’s all I got.

I bought Home Depot store brand of a 6 pack of BR30 indoor floods. Am keeping tabs on when and where I replaced the Incandescent bulbs just to keep up.
The standard style GE and Phillips LED bulbs stink. Flickering, last nowhere near as long as the old style.

Early edition LED light bulbs suck arse.
Posted on 2/12/24 at 2:46 pm to AndyJ
I don’t know about twenty, but I changed about 120 incandescents for LEDs and have only lost one in the 7 years since. I used to change a dozen or two per year.

Very few things piss me off more than going to buy light bulbs and realizing/wondering (1) how cheap they used to be; (2) how overpriced they are now; and (3) how many people are making millions off the scam "science" that precludes the rest of us from just buying some cheap fricking light bulbs.
It has already been mentioned but the savings are big on the back end. This is a post I wrote in November:
quote:
I have had a far different experience. I replaced all the incandescent bulbs in our house with LED bulbs in September of 2017. We have a chandelier in our great room that I put 6 of these bulbs in:
The first bulb failed last month so they all lasted over 6 years.
That light stays on about 15 hours a day so the dogs have one bright room while we are at work. We travel a good bit so very conservatively that were on 275 days a year. After I looked it up on Amazon and saw they lasted 6 years I was curious how much electricity they saved. I honestly didn't care the main reason I got them was to avoid having to get the 16' ladder out at least once a year because the incandescents were going out all the time.
The 6 incandescents drew 360w compared to the 54w of the 6 60w equivalent LED bulbs. So I rounded to a savings of 300w.
15 hours of 300w savings is 4.5kWh per day x 275 days per
year x 6 years times a very conservative .10 per kWh comes out to a savings of $742.50 over those 6 years.
The pack of 8 bulbs cost me $23.00 total so $17.25 for 6. Outside all the time I would have spent changing incandescent bulbs over the 6 years I still saved over $700 over the time.
I replaced over 100 other bulbs around the house and that one is the only one that has failed. The electricity I saved just in the one fixture paid for all those bulbs more than 2 times over.
My experience is obviously very different than some, it may be the bulbs I bought or I might just be incredibly lucky but my experience has left me in a place that I would not use incandescent bulbs even if I got them for free even if someone paid for the extra electricity just based on the trouble I have saved replacing bulbs in fixtures that are in high ceilings.
I absolutely love LED bulbs, I have several dozen incandescent ones left over and wouldn't even think about using any of them. Some people are more sensitive to the high frequency flicker but it doesn't bother me. Not dragging out the 14' step ladder and setting it up to change bulbs at least once a year is worth the price of admission to me. At least buying the quality of bulb I do and in our use case they save far more money than the extra cost and they are easily repairable but they lose a proportional amount of light output.
This is one technology that unless you are unusual and the flicker of quality bulbs bother you (cheap bulbs have cheap driver boards) I really don't see any downside unless you are using them in a manner where the heat produced is desired. For normal light bulb usage they save money and time replacing them.

Well written as usual. 
People generally have no concept of true cost anymore. It's been that way for a while but it seems to be getting worse. It's no longer just people not knowing the value of their vehicle outside of the monthly note. Maybe it never was but I just didn't notice.
