Apparently there were a lot of problems with the first wave of traffic light LED conversions in cold places because nobody considered that they didn't de-ice themselves any more, but that gets solved pretty quickly with heated glass or a nichrome wire in there somewhere.

Someone has to go around and wipe the snow off them in a city near me, or wait for the sun to shine on them.

I lived in a city that had snow six months of the year and the LED traffic lights had no problems because they all had sun visors on them which kept the snow off just fine. I'm not sure I've ever seen a traffic light that didn't have visors on it. Are there places where this isn't the case?

In my city they installed a single LED streetlight next to the city hall and put up a big sign about how it was a pilot program and how LED's would save the city so much money and be great for the environment and are generally fantastic and that was like 7 years ago and it's still the only LED streetlight in the city

The bottom cutout will keep the lights pretty visible during snow, but reduces the effect of the visor when the sun is just below the light.

It may have been said before, but I think it's pretty obvious what's so appealing about incandescents...the fact you can buy a shitload of them for 2 or 3 dollars! I've got CFLs and LEDs so don't think I'm some change fearing heathen, but I've got a few cheap rear end lamps here and there that are RARELY used that I just can't justify throwing a $30 LED bulb in. I've got 40 or 60w regular ol' electricity wasting bulbs in them and they work just fine the 3-5 minutes of use they get a year. I dropped $7 on a billion pack of incandescents eons ago and there are still about 1/2 a billion left. Same story with 40w bulbs for my fridge. I got a dozen pack who knows how long ago that I'll probably be using over the next 10 years. Sure I could probably save some major power over the course of a few months/years if I put an LED in there, but the ol 40 watters doing fine for now and has been for over 5 years since we got the fridge. I did however replace our 4 outside flood lights with LEDs (even though the old halogens worked fine and had for years) just because those suckers draw some serious juice, and I think the LEDs get better range/distance anyway.

LEDs aren't $30 anymore. The best 40- or 60-watt equivalent is around $10, less if you get a six-pack or wait for a sale. One question for me is what to do when you move. I live in NYC, so people move a ton, and I don't think anyone will want to leave $50ish in bulbs behind. When I upgraded to LEDs, I spergily set aside my old incandescents in the back of a closet.

Home Depot's running a sale right now with $5/2pk Phillips 60w bulbs. They're "only" 10 year life, so I don't know what the quality difference between those and the other Phillips, but if you're looking for some great priced bulbs, those are it.

Probably less change of counterfeit electronics inside the thing. At less cheaping out on every single aspect of the power supply. The difference between a binned Cree LED and some noname shitbox LED can be pretty extreme.

Baronjutter posted:If I bought a full-price LED at a shop here would it most likely perform better than my direct from china $10 "2000 lumen" bulb? More expensive bulbs have better ventilation, aluminum heatsinks, and even fans to keep temperatures down, which improves lifespan significantly. The general rule with electronics is that for every 10 degrees Celsius that the temperature goes up, lifespan is halved. Less expensive bulbs are rated for much shorter lifespans because of this. This may not matter so much if you're using the bulb in a cool, well-ventilated area, but if you stick a poorly cooled bulb in an enclosed fixture it won't last very long. Do keep in mind if you're chasing longer lifespans that the LEDs themselves are still going to shift in color and decrease in light output (and thus efficiency) over time, so after a certain point you might start to think about if keeping each bulb longer is really worth it. The quality of the electronics and their physical construction determines if any flicker is visible, and whether the bulb gives off a hum or whining noise while operating. The power from your wall is 60Hz AC, so without a smoothing capacitor you'd see the bulb flicker 60 times per second, like an old-style CRT monitor or ancient magnetic-ballasted fluorescent light. Even the cheapest bulbs have smoothing capacitors so flicker shouldn't typically be visible, but it will present and measurable on all but the most expensive bulbs. Similarly, coils are glued down with potting compound to keep them from vibrating in an audible way. The best bulbs have the electronics completely potted in blocks of glue and will have no measurable sound emissions, though even the cheapest bulbs have enough potting to keep the sound from being audible for most people. I own Cree 4Flow LED bulbs that are very cheap and have both measurable but not awful flicker and coil whine, but I can't see or hear anything. I'm pretty sensitive to flicker and was to coil whine in the past, but I'm over 30 now so can't guarantee I still have the high frequency hearing to pick it up. Dimmer compatibility is pretty obvious, if it doesn't say it's dimmable it likely isn't. Check out electronupdate on Youtube for sperg-level teardowns and reviews of LED lightbulbs, including flicker, noise, and temperature measurements. Here's his review of the Cree 4Flow bulbs, which I really like despite his low opinion (maybe my opinion will change if mine die prematurely: https://www.youtube.com/watch?v=0jtx7jhZLNM

The fact that incandescent light bulbs are designed with the understanding that they can get very very hot, makes them well-suited for use in ovens. I'm not sure if there are any LED oven lights that go inside the oven. Can an LED handle 550+ degrees F? nm posted:It bit the guy who mows his lawn. No. That guy went into the back yard with a friend of his, and the friend was the one who was bitten. So, the dog protected the property from an unknown stranger who hadn't been there before, who had no permission to be there, and was let in by the neighbor who regularly mowed back there but always with explicit permission.

He may be telling the truth, but I'm taking it with a grain of salt. Yeah, that "explicit permission" thing is bullshit. There's no way they OK'd every time he'd mow the yard once it became a regular thing. My neighbor's little kids always end up with a ball or frisbee or something in my yard, I usually toss it back over the fence if I notice. I've told them to feel free to come into the yard and grab it themselves, just peek over the fence and make sure the dogs aren't out. The thing is the dogs would never attack, but I don't want the neighbor to worry about it (although the whole family of them has met the dogs). Plus they're *never* out if I'm not home and have no way of getting out.

The thing is the dogs would never attack, but I don't want the neighbor to worry about it (although the whole family of them has met the dogs). Plus they're *never* out if I'm not home and have no way of getting out. The lawnmower guy can easily make a (legal) argument that he had permission to access. On the other hand, he presumably knew about the dog. He also presumably knew the owners weren't home. And, as a homeowner, you do not have a responsibility to make sure that your dog can't bite someone who comes onto your (fenced-in) property and who you don't know. I mean, think about how ridiculous a standard that would be? People own dogs in part specifically to guard their property! And it's not like the dog ripped the guy's throat out, either. It bit his leg and then retreated when threatened. I think the landowner had an excellent case for refusing to pay medical expenses for someone who was trespassing, although probably not standing to actually prosecute for tresspassing (because like I said, the actual neighbor clearly had permission to enter based on previous lawnmowing arrangements). It all goes out the window though when she erected a fence and painted it garish colors, only on the neighbor's side, just to piss him off. Now instead of her explanation of the lawnmowing and dog-guarding arrangements being those of a reasonable neighbor (and see the emails, she was being polite and reasonable after the incident too), they're the word of someone who clearly isn't acting like an adult in the situation, so the judge can discount them. This is a matter for small claims court, there's no jury, and most likely if legalities come into play it'll be each side's lawyers strenuously advising them to settle the matter out of court. So we're all just armchairing here. I'm just saying: you bring a stranger with you to someone's property where you know there's a dog, and you can see they're not home, then it's on you to make sure your buddy is safe.

I have no idea if this is how it works, but I would assume the incandescent bulb will continue to stay lit when the batteries are drained more. I have no proof/evidence or facts to support that claim it is just speculation based on the fact that the voltage the batteries output drops as they die and an old fashioned incandescent probably cares less about the voltage drop than a high tech LED. That said, everything I see on Amazon for LED headlamps claims 50+ hours of life on AAA batteries, either you got something brighter than the sun or it's old an inefficient.

That's awesome I didn't realize how cheap LEDs had gotten. Any suggestions on what to use in say a fancy bathroom light fixture? I think the proper term is makeup table, like this: Keep in mind this isn't mine, but the wife and girls have something that's basically the top 2/3 of that. I'd consider myself a borderline CFL expert but I'm dreadfully behind the times LED wise and all of the CFLs we've tried in the past just didn't look right (the various CFLs were put to good use elsewhere so no worries)

I use them in my kitchen and it's really neat. That's just considering the aesthetics of the light, though. The aesthetics of the bulb are a different story, because they probably aren't going to love the look of a dozen exposed LED bulbs. I have a similar strip, and I actually stocked up on those incandescents before they were discontinued, because I don't think anything else looks right. I always do daytime makeup by natural light, though.

They are indeed enclosed in a "square can" style fixture from the 50's. It's the worst loving thing - a 12-inch square that's flush with the ceiling. Inside is an asbestos box and a curved reflector that sits right above the bulb. Unfortunately it does little since there's a frosted/textured plate of glass that prevents half of the light from escaping. The place was dark and dismal with 60w bulbs, so I popped in 100w LED equivalents. I figured since they produced so little heat the enclosure wouldn't matter, but I guess these things are delicate with heat.

Perhaps by restaurant they meant atrium bar and grill in a 30+ story hotel? And the bounce back to ugly-architecture chat for a moment, a couple alums of my tiny liberal arts college got together some funds to build a new art building back in the eighties, with the biggest contributor insisting on choosing the architect. Said wunderkind created a sleek, white stucco building that looks like the love child of Minas Morgul and the Hoover drat. The rest of the college is typical 19th century brick and stonework. It took the college six months to raise funds to build a wall around the thing.
