  1. Re:It's the heat that kills LEDs/CFLs on The Great Lightbulb Conspiracy · · Score: 1

    LEDs don't throw off more heat than CFLs. That would violate the laws of thermodynamics. It's just that the LEDs themselves are sensitive to the heat generated by their support components, so they must be protected. For CFLs, the light-generating part is not a solid-state component, so it doesn't need protection. The LED and CFL ballasts both generate much (or most) of the heat.

  2. Re:electricity is expensive on The Great Lightbulb Conspiracy · · Score: 1

    LEDs are only expensive if your electricity is free.

    Clearly not. If my electricity is $0.01/kWh, then it will take 8.5 years just to pay for a $10 LED. Is anyone paying only a penny per kWh? No, but I just refuted your claim. FWIW, I'm paying about $0.10 a kWH-- including the delivery charges, which people forget about-- so it would take me about a year to pay for a $10 LED. A lot of people aren't getting even a year out of theirs, so you can see why they are upset.

  3. Re:bathtub curve applies on The Great Lightbulb Conspiracy · · Score: 1

    The mains switch at the panel, or the circuit fuse? If the latter, those LEDs seem to have a dangerous failure mode that causes a short circuit instead of an open. For the former, you have a problem with your service that is due to either power surges or an overload on the amp rating of your service. Either one is a bit unsafe and should be looked into.

  4. Re:Its not the CFL/LED on The Great Lightbulb Conspiracy · · Score: 1

    This seems feasible. There are already form factors designed for track lighting and small spots that use DC bulbs. Seems like if you replaced these (usually tiny, expensive halogens) with LEDs, they'd probably last forever.

  5. Re:I'm sold on LED bulbs... on The Great Lightbulb Conspiracy · · Score: 1

    That's the one funny thing I've noticed. Seems like the manufacturers should be slapped with a class-action lawsuit for their rating of CFLs per their equivalents. I've seen ~600 lumen bulbs labeled as "60-watt equivalent". Meanwhile, LEDs seem to be sandbagged; the best LEDs I've purchased so far were at Goodwill for a DOLLAR and even though they said 40-watt equiv, they were as bright as the 60 watt incandescents they replaced.

  6. Re:I dunno about LEDs, but CFLs don't last on The Great Lightbulb Conspiracy · · Score: 1

    I can agree that Sylvania makes a good CFL, for a CFL. Philips is OK, and GE is terrible.

    Philips look good, but they only seem to last slightly longer than an incandescent. GE bulbs die within a 1,000 hours if they aren't installed screw-down, and many of them have a disgusting pinkish hue at half brightness for the first 30 seconds.

  7. Re:I dunno about LEDs, but CFLs don't last on The Great Lightbulb Conspiracy · · Score: 1

    Many LEDs will work with conventional dimmers. CFLs, no. But CFLs stink for anything that isn't an indoor, non-fan, non-3-way, non-enclosed, fixture or lamp with a vertical screw-down socket.

  8. With incandescents, it's two out of three on The Great Lightbulb Conspiracy · · Score: 1

    While still a cartel that should have been broken up much earlier, with incandescents it's true that out of low cost, efficiency, and long life, you get to choose two. "Long life" (now pretty much outlawed in the USA) and especially "rough service" bulbs (which are sold through a loophole) use a thicker filament. A thicker filament remains intact longer, but is less efficient. The "low cost" part comes in with the halogen bulb. Its design rejuvenates the filament so that it lasts longer, allowing for a thinner filament, but it costs more to manufacture.

    No, you're not. Do you live in the woods? If you live in a town that has municipal trash collection, IT IS A MONOPOLY. Some communities contract a firm ostensibly to reduce traffic on roads, even.

  13. Question for Seattle on Seattle Passes Laws To Keep Residents From Wasting Food · · Score: 1

    Politicians and activists are so good at ignoring unintended consequences.

    Where are people supposed to keep all these separate bins in their kitchen? My count says they have four: paper products, aluminum/plastic (hopefully these can be commingled), unrecyclable plastics/cloth, food scraps. This doesn't even address the bins you have to have to hold "hazardous items", like your batteries, fluorescent bulbs, paint, etc. in other areas of your home.

    How do they separate this "compost" stuff from the plastic bags you have to keep it in? Or do they expect people to keep vermin-encrusted bins in their home?

    What's the answer?

    What makes you think people with municipal trash collection don't have to use it? You 100% have to use it, or you don't get your trash collected and I'm pretty sure hoarding trash in your house is also illegal.

    You're confusing them with socialists, I think. They're convinced they're so smart, they should make decisions for everyone else. Believing that I should allow other people to make their own choices seems to be the opposite of elitism.

    I'm not sure why you decided to be the poo-flinging primate in this discussion, but acting as if there are no facts behind the Bible is utter nonsense and anti-intellectual. I'm not asking you to believe that Elijah was carried up in a flaming chariot, but to realize that most of the people, places, and events recorded have been corroborated by archaeology and contemporary sources. Meanwhile, when you make sweeping statements like "isn't a single tale of religion that is substantiated by facts", it sets a pretty low bar for people to dismiss you.
