It's not well suited for LEDs of the same power as incandesces. --- End quote --- Agreed, but the difficulty there is the ubiquity of ES and BC variants, in domestic settings. I have found 2D LED replacement lamps to be of pretty good quality and longevity on the whole, but all the new fittings that would have had 2D lamps in them are fully integrated now, often with crappy microwave sensors that introduce yet another failure mode that leads to a whole-fitting replacement. Just for shits and giggles, here's what a chandelier looks like when populated with CF lamps :palm: |

It's a pretty shit conversion regardless of the lamps, I don't see why they even dangled the bulbs. CFLs don't make it much worse. |

Is there anything in this thread that is rational or actually thought out? This is one of the biggest BS threads at EEVBlog. |

I agree with PlainName here, that sounds exactly like what a company would do. If they were going reduce the brightness, they'd just reduce the number of discrete LEDs to save on cost, and still run each element at a power level that will target a certain lifespan. This is why I have moved towards separate LED arrays and drivers. Commercial grade lighting is a good way to get off the shelf components as you can get passive LED fixtures then choose a driver which runs the LEDs conservatively. It also opens the possibility for dimming, external control and automation etc, but is still simple enough for a sparky to do a regular light switch install. |

--- Quote from: tooki on August 06, 2023, 03:08:32 pm ---If we implemented a ban like you suggest, the ultimate result would be that the maximum wattage of the LED lamps would be cut dramatically, forcing people to use lamps that are not bright enough for their needs; warm white would disappear; and flicker would increase as manufacturers switched even more lamps to simple capacitive droppers. I don’t think this is a viable solution. --- End quote --- Flicker is usually counter productive to efficiency due to the massively non-linear characteristics of LEDs, buying on (fixture/instrument) lumens per watt is a pretty good guide. |
