Expensive but a good idea. >> Bob, there's one other bulb in the package. I'll try that >Another model or brand is more likely to make the needed difference. You're right. I put the noisy LED bulb in the ceiling fixture and now it's about 5 feet from the radio and doesn't interfere at all. It's called "daylight" and at 100 eq. watts it gave a very strange appearance to the room. I'll probably get used to it. They didn't have anohter low-cost LED at HDepot and ... I'll probably get used to it. After all, it's "daylight". |

With LED devices, the CRI (Color Rendering Index) for such a (cheap) lamp will be somewhere between 50 and 80, or in other words, pretty wretched. LED lamps with both a high CRI and a high K tend to be costly relative to the cheapies. Strange appearance, indeed. Peter Wieck Melrose Park, PA |

vhm.14u2c@gmail.com: Jun 06 06:14AM -0700 I have the same problem, Sony reciever str-av570, that keeps going into protect mode intermittently, even when the reciever is off, will intermittently do relay click and loudness amber led(s) on the front will glow gradually, off, and repeat till I unplug it. Back in 2003-2004, I took my reciever to a authorized sony service center that did not know how to fix it, but charged me $35 to inspect device anyways. From the replies on this post, looks like a good place to start. Thanks for sharing! |

This makes it a PITA to get audio out if the set does not already have that feature. I needed to use small audio transformers and low pass filters to get the switching freq down. And after all that, there still was no bass, I had to find a hidden sub menu to change the audio mode to full range. mark |

First off, learn how to use your editor. There's absolutely NO reason what so ever to include the entire two previous posts. Secondly, wind is no more or less stable then the supply chains for gas and coal. As a matter fact, several major coal companies have either filed bankruptcy, or have shut down entirely. Natural gas ain't exactly fool proof either. <https://en.wikipedia.org/wiki/Aliso_Canyon_gas_leak> Wind farms are expensive, they tend to do a serious site survey as to the constant values of wind speed. I.e. 24/7 availability. Then, of course, you had clowns like Enron shutting down various facilities just to increase the spot pricing of electricity. But go ahead, keep finding fault in that which you don't understand. -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com |

"pfjw@aol.com" <peterwieck33@gmail.com>: Jun 06 04:14AM -0700 Jeff: Tabby gives clear and direct meaning to the term "invincible ignorance" as no matter how clearly they might be presented, he will not be confused by mere facts. The Iberdrola wind farm in Colummbia County, PA has a reliability record that matches Berwick Nuclear nearby. https://en.wikipedia.org/wiki/Locust_Ridge_Wind_Farm It will make 'nameplate' at any range from 7 mph to 54 mph wind-speed. And its site will deliver that 7 all day, every day. Peter Wieck Melrose Park, PA |

And its site will deliver that 7 all day, every day. > Peter Wieck > Melrose Park, PA Let's establish some actual facts if we can. Your link says: "The wind farm has a combined total nameplate capacity of 26 MW, producing about 68,328 megawatt-hours of electricity annually, 26MW x 8760hrs = 227,760 MWh if it ran at 100% capacity, which of course it can't. 68328/227760 MWh = 30% capacity. A conventional plant with only 30% capacity is a disaster if you need to rely on its output at times. With a wind installation at 30% the operator is not in control of its uptime, that is left to the vagaries of nature. Hence with such generation, to keep the lights on one must have duplicate controllable generation of the same capacity elsewhere - and that makes the wind farm a pointless spending of money. It is nothing more than a political appeal to ignorant greens. To say the windfarm is comparable to a coal plant shows a fundamental level of ignorance of power generation. NT |
"pfjw@aol.com" <peterwieck33@gmail.com>: Jun 06 04:52AM -0700 You need to get out of theory and into actual practice. Again, you seem to accumulate only those facts as fit your ignorance. Locust ridge is operating with 64 turbines at just under 67% of nameplate capacity. Which is entirely to be inspected as a group of those turbines are typically down for *planned* service & maintenance. The most efficient coal-fired plants on the planet operate at 40% energy-transfer efficiency, and are down, on average, about 30 days per year for maintenance, three times that about every 3-4 years. That is in actual practice. Not theory. As with LED drivers - just look at the typical RAB or CREE exterior LED lamp - and ask yourself where the heat-sink(s) is (are). On the driver? On the emitters? And, most of them make 130 lumens per watt, or more... right now. Peter Wieck Melrose Park, PA |
tabbypurr@gmail.com: Jun 06 05:24AM -0700 > You need to get out of theory and into actual practice. Again, you seem to accumulate only those facts as fit your ignorance. I see you're keeping up the bs. Let's look at some facts instead... > Locust ridge is operating with 64 turbines at just under 67% of nameplate capacity. the numbers you referred to show 30% capacity. No wind farm manages 67%. 30% is good going by wind standards. > Which is entirely to be inspected 67% of capacity would be an amazing achievement for any windfarm. Even if one day that can be achieved - and the theory indicates it can not - it still would not be able to replace conventional generation. > as a group of those turbines are typically down for *planned* service & maintenance. The most efficient coal-fired plants on the planet operate at 40% energy-transfer efficiency, their energy transfer efficiency has absolutely nothing to do with this. Zero relevance. > and are down, on average, about 30 days per year for maintenance, three times that about every 3-4 years. Every type of plant goes down for maintenance. Being able to plan that downtime is a lot more useful than being at the mercy of partially-predictable wind. > That is in actual practice. Not theory. Well, it isn't but hey. > As with LED drivers - just look at the typical RAB or CREE exterior LED lamp - and ask yourself where the heat-sink(s) is (are). On the driver? On the emitters? That you think the SMPSUs used are below 50% efficient shows gross ignorance of lighting products & PSU design. Discussing the heatsink question at the moment seems pointless. > And, most of them make 130 lumens per watt, or more... right now. > Peter Wieck > Melrose Park, PA Some may, and more has been achieved. But the average product in the shops here certainly doesn't. NT |

"bargain basement" was a commentary on the quality not the price, rather, they're not even that much cheaper as compared to competing products in the same class from e.g. Asus, IMO a better supplier in most respects based in Taiwan. |

Mostly a slam at their US-based service. Under IBM I'm sure it was pretty good for the product. this repair case was sent to their main US center and they can't even print up a replacement serial # sticker (for the one that was never affixed at the factory.) they're using marker. marker! you're using coconuts! - <https://www.youtube.com/watch?v=3XPnIUtcANg> |
