I encounter that a lot in this forum. If you take moderate position on something, you immediately get slotted into the camp that is the polar opposite of their opinion. I think some people just like hearing the sound of their own voice. |

You're mincing words. --- Quote from: james_s on February 08, 2019, 09:45:04 pm --- "but what about this edge case?" --- End quote --- Geez I'm so picky for wanting to light my living space to suit my needs which, by the way, didn't use to be a problem. To me it is a downgrade. Sue me. --- Quote from: james_s on February 08, 2019, 09:45:04 pm --- "I tried a 99 cent unbranded Chinese bulb and it crapped out after a week --- End quote --- You're not gaining any credibility with fabrications like this. I specifically mentioned branded bulbs. --- Quote from: james_s on February 08, 2019, 09:45:04 pm --- so LED bulbs are all junk thought up by some kind of liberal conspiracy!" --- End quote --- And here perhaps your motivations are peeking through. Is this a political issue for you? |

--- Quote from: james_s on February 08, 2019, 09:45:04 pm ---What I see are people making blanket statements that lamps with these specs don't exist when in fact they do. Need 100W equiv? --- End quote --- That's just the the thing "equiv" doesn't just mean the same output. If it doesn't mean "able to fill the same role", then it is something less than equiv. --- Quote from: james_s on February 08, 2019, 09:45:04 pm ---Philips makes a 1600 lumen A21 LED bulb, they're available at Home Depot among other places and they work fine, I have one in one of the few applications I have for such a bright lamp. --- End quote --- All of the bulbs I have tried that have failed were purchased at HD. These were not crap brands like "Feit" (though I have tried that, too.) I've had failures inside 1 year with Cree, GE, and Philips. --- Quote from: james_s on February 08, 2019, 09:45:04 pm ---No need to get new fixtures, there are retrofit bulbs that will tolerate most types of existing fixtures, for example these are rated for use in fully enclosed fixtures https://creebulb.com/60-watt-replacement-soft-white I have some of the previous generation in small enclosed ceiling globe fixtures and have yet to see a failure. --- End quote --- I was not aware of this bulb, but I was in HD today and saw it. Om your recommendation, I bought two and will revive this thread in a year to report back. --- Quote from: james_s on February 08, 2019, 09:45:04 pm ---There are many poorly designed LED retrofit bulbs out there, and many that work well in some types of fixtures but are not appropriate for other types. It's not as simple as it used to be where you'd go out and buy a pack of bulbs of a given wattage and they would just work, but bulbs that work are available for a majority of applications, it's not as if they don't exist or have not yet been developed. --- End quote --- No, it's not as simple as it used to be, and it seems the bulb manufacturers are not doing much to help. For example, here is a photo I took today of a GE product: Spot the section where they mention it can't be used in an enclosed fixture? It's there. --- Quote from: james_s on February 08, 2019, 09:45:04 pm ---Also yes I will concede there is some arrogance, but also I see the same attitude as pops up in nearly any EV-related thread of "Well it doesn't work for my use case so it's a silly idea that is completely pointless all around and will never work" or "but what about this edge case?". Or the old "I tried a 99 cent unbranded Chinese bulb and it crapped out after a week so LED bulbs are all junk thought up by some kind of liberal conspiracy!" --- End quote --- A few points: - first, the problems do not all come from 99 cent unbranded Chinese bulbs. And in fact, probably all the bulbs are Chinese in origin - your edge case is my normal case. For your EV example, I drive crappy, utilitarian cars, like a Honda Fit, which I bought new for $16.5k about ten years ago. It can go 250 miles on a tank and gets about 20 locally and 40 on the freeway. Is there an EV that fits that niche? Not even close. Is it an important niche? To me it is. Are there awesome EVs? Of course there are. Will there be an EV soon that fits my mission profile? Dubious. - the lightbulb industry just so happens to have a documented history of criminal conspiracy: https://en.wikipedia.org/wiki/Phoebus_cartel |

--- Quote ---- first, the problems do not all come from 99 cent unbranded Chinese bulbs. And in fact, probably all the bulbs are Chinese in origin --- End quote --- A lot of western companies produce nowadays in China. The big difference is that they supervise these factories, have strict requirements about the brand components they should use, etc. Your statement says nothing. Still as I already stated even brand producers are nowadays selling cheap products that have dubious lifetime because the market demands those products. For some applications as an attick where you come twice a year that might be very acceptable. But a lot of people make the mistake putting these bulbs in sensor switched fixtures where they might well get 5000 switch on/offs or more per year. They are not designed for that. If you want that you should as an exaple use a Dali sensor that sends a Dali message to a Dali driver that is mains powered on 24/7 and is always in low power standby. But as said earlier hard to explain to grandma Jones, hell it is obvious from this topic that even EEs sometimes have no clue and start brabbling all kinds of nonsense from their statistical experiment with n=1. :palm: |

All bulbs I buy at my local home improvement store should be able to withstand being switched on and off, many times per day. I think that is a reasonable expectation. |
