There are many good quality LED bulbs on the market that provide an excellent facsimile of an old fashioned tungsten lamp, and you can still get tungsten lamps for the niche applications they are really needed. Having not used one for general illumination in nearly 20 years I'm frankly always a little shocked to find that there are still people using them outside of special applications and nostalgia. They're as obsolete as oil lamps IMO, which are also still readily available for decorative and nostalgia uses just like tungsten lamps. There is no reason to use incandescent for illumination in a modern home or commercial building. --- End quote --- To avoid derailing the thread, I will keep it brief. I can believe there are better led bulbs out there now. In general (because if I, for example go into a shop, I've got no control over the leds they use), they can be too bright, wrong light colour, flicker (to some extent), and be annoying to my eyes. Similarly, modern street led lights (UK), although usefully bright when you need it, can be annoying at times, too bright, painful to look at the lights themselves, flickery or something, which at least a bit annoys me, bit of a funny light colour. Etc. tl;dr Just because you are 100% happy with something. Doesn't mean it can be rolled out to everyone else in the world, and expect 100% of other people, to also be 100% happy with them. Sadly, life is not like that. |

--- Quote from: james_s on July 26, 2020, 07:03:45 pm ---My friend was a stay at home dad for the first few years after his son was born while his wife worked full time to bring home the bread. He quite liked it, he always had plenty to do and it was his first "work from home" experience prior to his current corporate job where he also works from home full time. He has commented that there was a great deal of stigma though, many view a man who doesn't work a real job while his wife supports him as being a lazy bum, even if he's busy raising the kid(s) and keeping the house from falling apart. Now he spends a good bit of his salary hiring people to do the things he used to do himself when he didn't have a real job. --- End quote --- The plan with us was that I'd be the stay at home parent and Mrs EEVblog would go back to work. As she earned more than me at the time and had the "career" rising up the ladder, and I had my side kit businesses and consulting design stuff I could do from home. Made sense. But when the blog really started to take off and earn more than her, it became a quasi "kid share" thing where she only worked a few days a week instead. As she didn't want to give up the career, and I didn't want to give up this new fangled Youtube thing but had the flexibility to mind the kids when needed. That's how it still is today. |

The reason for making incandescent harder to buy is because many people used to get them because they were cheaper to buy, than CFL and LED. Environmental issues aside, the total cost of ownership of LED and CFL is less, than incandesant, due to the power savings. I've had mixed experiances with LED lamps. Most seem to last a long time, without any flicker. The worst ones have been those I purchased cheap off ebay, which tend to blow up fairly quickly, due to bad capacitors. The better ones are from a supermarkets, rather than online. The regulators need to do something about the cheap crappy kind which flicker and don't meet their specifications. |

I've got moderately expensive, Philips led lights, in the room I'm in. Around £4 each, for a pack of around 6, 100 watt equivalent. The light is reasonable. But does seem to be flickering. If I rapidly move my hand, it seems to get the characteristic strobing effect, of flicker. Doesn't seem particularly high frequency flicker, either. Suspect mains frequency. But I could be wrong. I'd better stop now, as off-topic, in this thread. |
