Some at least attempt but only get it about 70%. I have a bunch of Philips Hue RGB bulbs and those do a pretty good job but the red is an orange-red rather than a true deep red so yellow is kind of a sickly greenish. --- End quote --- They exist, using neutral white and very warm white LEDs, blending as needed. Very different (superior) effect than RGB bulbs. --- End quote --- Can you point us to some references? At a reasonable price point? --- End quote --- Remote control dimmable: https://www.ikea.com/gb/en/p/tradfri-led-bulb-b22-1055-lumen-smart-wireless-dimmable-white-spectrum-globe-70517641/ TRIAC dimmable: https://www.amazon.co.uk/Philips-Classic-WarmGlow-Dimmable-Filament/dp/B073FMGQ4X I guess you can find comparable examples in your country's stores. |

--- Quote from: tooki on April 09, 2023, 12:12:33 am ---It stems from the fact that we consistently find right-leaning media to report more falsehoods than left-leaning media. (Neither side is perfect. One is just consistently worse.) --- End quote --- That's a joke. It's obvious your bias is at play here. There's nothing wrong with that of course, but it's important to be aware of ones biases, even though it is difficult. --- Quote from: Simon on April 09, 2023, 06:43:07 pm ---As for everything else we are happily offshoring our footprint. We don't make very much in rich nations, we import it so our emissions have simply migrated. Yes lots will argue that this is not their problem, well to every sensible reasoning their will be hundreds of stupid retorts. Let me see, has international trade gone down or up over the last few decades? Who are we trading with and how do they make our junk? yes junk. If a throwaway society is how you want to fuel economic growth then lets hope those developing nations are getting their faster than they are churning through the natural resources or by the time their are "rich enough to care" they will only be caring because they have to anyway. --- End quote --- Yes that's true. Originally it started because labour is cheaper in less developed countries and they often have the raw materials too. Environmental protection laws in developed countries have actually made it worse, by making it more more expensive to manufacture goods domestically, so importing makes even more sense. Net zero will only make it even worse. |

--- Quote from: 5U4GB on April 13, 2023, 05:57:48 am ---The problem is that people go out and buy the cheapest lights they can find off Aliexpress and then wonder why they're getting blue-tinted flickering. I must admit I was surprised by these ones given how much junk is out there, but they've got good-quality diffusers to get an even colour spectrum and don't flicker at all. They've also got a massive heatsink that's bigger than the entire rest of the luminaire, good-quality electronics... and a price to match. Another problem with many cheap LED lights is that you're getting the raw LED output, or close to it, so they can be advertised as 6.023e23 lumens rather than sacrificing a small amount of output to get better-quality lighting. And then throw in some Gluxon capacitors... and the metal cap on the end is fine for a heatsink, right? --- End quote --- That's the problem with everything, many/most people shop almost purely by price. Two things look almost the same even though they're not, so people buy the cheapest one, then complain that it sucks. I don't really know how to fix that other than education but that's easier said than done. I try to avoid it when I can, I've bought quite a few Hue LED bulbs which are certainly not cheap and they're quite good, but they could be better, incorporating some true red emitters for example. So far I've only had one of those fail and thankfully it was a relatively cheap 2700k white one and not one of the tunable CCT or RGB bulbs. |

LED lights for general applications could have mandated CRI, flicker levels, and efficiency, and be required to pass various accelerated aging tests to improve reliability. You could also mandate both long warranties and long-term compatible replacements (I'm looking at integrated fittings, especially downlights, here. With some anger.). |

I haven't heard this. although it wouldn't surprise me in some of the People's Republics. --- End quote --- Of course, in some parts of the world, it seldom gets dark enough during the day to need the use of headlights! |
