It is a bit like, when you meet up with someone, and they take you to a shop, to buy three printer ink cartridges, for £19 each (price completely made up), almost £60. As they explain their printer needs them every couple of months, for the 100 pages they have printed. You explain that it is cheaper in the longer term, to buy a more expensive printer, but with considerably longer lasting, and cheaper (overall), supplies, such as toner. Yet, they say the printer only cost £29, so it MUST be the cheaper option, compared to the £200 printers, I'm suggesting, maybe they should have bought. I think part of the problem, is that people don't necessarily even see the mathematics, of £60 x 6 (if every 2 months) = £360 per year. Whereas a £200 Laser printer, or modern eco-tank printer, with the odd £10 .. £100+ toner/ink refill, every couple of years or so. Would be considerably cheaper in the longer term. Yet they keep on shelling out, £60 (or whatever the cost is), for three printer cartridges, until the next 100 pages are printed out, so around another couple of months. |

Tooki, you almost got it right, (which is why I pushed the 'thanks' button). However, we are going to need a good sweep, of corruption. Always always always there's gonna be some dumb-ass messing with and twisting the agenda...because that's the way things have been unfolding. I observed the push, to get Americans out of their cars (Pres. Obama 2009-2016.). Meanwhile local BUS services cut like mad, 2013 Alameda-Contra Costa counties. I noticed our US Transportation Secretary projects a sense of incompetence, (and how he talks), incompetent in the very expertise needed to declare technical things for us to follow. Yeah, 'not banned', it's just that,...wait, ... 'EU BANS 8k' that's the title of this thread. And I get to 'argue' that ? No thanks, I'm prioritizing my time, to some degree. |

They cost more to buy, produce adequate light initially, but their output falls off rapidly, radically reducing their useable lifetime. Contrast with conventional Fluorescent tubes, which still produce substantial levels of lighting, up until they start to flicker, then rapidly drop off, after a much longer lifetime than CFLs. The idea of somehow squishing a "fluoro" up to fit inside a "light bulb" was doomed from the start. The first LED bulbs were nice & efficient, but their light levels dropped off rapidly in service. More recently, this problem has been overcome, & the current generation deliver on the promises. |

They were not perfect by any means but for the most part I didn't have a lot of problems with them. The brightness does fall rapidly over the first 100 hours to around 90% of initial and then follows a much slower decline until they reach 70% at which point they are considered end of life. They worked particularly well for me in dusk to dawn lights outside where I regularly got over the rated lifespan of 6k-8k hours. LED is better, but CFL was hardly the worst thing, they worked well enough for me that I haven't used incandescent bulbs for general illumination in over 20 years. I have not seen the lumen decline of LED bulbs, even early ones. The Philips 8W LED in the porch light by my front door was installed in 2011 and runs dusk till dawn 7 days a week. It is indistinguishable from a NOS one I never ended up using. |

I have replaced most CFLs with LED a couple of years ago when LED had matured enough to be cost effective and work well. I had an early LED lamp but that was pretty crappy. My experience with CFL bulbs is that the more expensive, long life ones have a long lifespan but they tend to startup slow. The cheaper ones crap out quickly. I have replaced the CFL tube armatures I have with HF drivers. HF drivers make the tubes last almost forever. Though I have not found LED panels that have >90% CRI like the CFL tubes I have in my lab and workspace so I'll stick to CFL in there. All in all I must say that the modern LED lamps certainly are very good and offer a lot of lighting possibilities that are not possible with incandescent or CFL. |
