This seems to be quite typical for government consultations. There's very little in the way of rigorous process. I remember years ago in the UK there was some poll that showed people were worried about anti-money laundering laws and their effect on freedom and civil liberties (it was a poll about risks to civil liberties, Ithink). So the British government said they'd respond to this by ordering a consultation on how best to improve Britain's AML laws. They invited public comments, etc. 6 months later the consultation was published and it recommended making the laws even stricter. There was absolutely no evidence-based approach used at all.

I wonder how much of that is because of the way you're using them. They give a lifespan estimate, but that's making some very broad assumptions about how you use them. Those estimates about how many years they'll last are based on you using it for so many hours per day but only turning it on a few times per day. If you turn the light on and off many times per day, as you might in a bathroom or if you're using an occupancy sensor, the filaments will wear out a lot sooner than the projected lifespan. If you're really turning the lights on and off a lot, LEDs are probably a better choice.

Their energy savings is not that much better than CFLs...

That depends on what you consider "much better". The newer LED bulbs at big box retailers like Home Depot are now using around 1/3 less power than equivalent CFLs. That's not the same kind of savings you get from switching from incandescent to CFL, but it's still substantial. If power costs more than about $0.10/kW, they're probably worth the increased up-front cost.

+ - Tesla Battles Trademark Troll in China

Submitted by cartechboy
cartechboy (2660665) writes "Looks like Tesla is battling copyright issues over its name in China, as a single businessman there trademark trolls them. Zhan Baosheng has sued Tesla to stop the company from selling cars in China because he filed for the Chinese copyrights of the Tesla name in 2006 and was granted those trademarks in 2009. Baosheng had also set up a website and trademarked the Tesla logo--hoping to profit from Tesla's expected plans to sell in cars in China. Tesla, meanwhile, says its claim to the name has already been upheld by other Chinese authorities and that the lawsuit is without merit. The electric car company has actually considered using the phonetic name "Te Su Le" to sell its cars if needed. China drivers now buy more cars than those in any other country and the market is a key for luxury car sales."

Sometimes, the cheapest and most efficient LED bulbs are in the blue end of the spectrum, especially when the color temperature doesn't matter too much - like a flashlight.

In that case, it's not so much the color temperature as it is the spectrum. The color temperature tells you what temperature of blackbody radiation your light source most closely resembles, but it doesn't tell you how closely it resembles it. Our eyes work best with light that has a distribution similar to blackbody radiation, i.e. with a wide, smooth distribution of wavelengths. If the distribution has sharp spikes, it can cause things to look the wrong color compared to what they're expected to look like. This is most obvious if you get one of the LED lights that uses a mix of pure red, green, and blue to simulate other colors; you can get something that looks like white if you look directly at the lights, but nothing they shine on looks right. That color shift is what CRI (color rendering index) is supposed to measure.

Lights have to have a CRI of at least 80 to qualify for Energy Star, which means that most household lights are now fairly decent. Cheaper lights and ones not intended for general illumination may go for higher efficiency at the cost of lower CRI, which is what you're probably noticing in the light from flashlights. High CRI (90+) lights are available, but they're usually a bit more expensive and less efficient.

Generally speaking, anything with lots of parts has more points of failures.

Maybe that's true in general, but in the specific case of lighting, incandescent lights obviously have a much shorter life span than CFLs or LEDs. There's plenty of reason to think that incandescent lights do badly with power spikes. My experience is that they're a lot more likely to fail when you turn the light on than any other time, which suggests susceptibility to power surges. It's just that replacing dead incandescent lights is a regular activity, so the occasional failure due to power spikes is much less noticeable than for a light you expect to replace once or twice a decade.

I wouldn't be so sure that energy efficient lights a lot more sensitive to dirty power than incandescent lights. It's just that incandescent lights have such a high background failure rate. If a CFL or LED light dies, you assume there must be a problem with it because their rate of natural death is so low. With incandescent lights, you would have a hard time telling whether one died because of bad power or because it's just given up the ghost.

IMHO all this tech is basically good, but I should point out that I also consider a large wooden horses to be basically good things, too. (They can be neat works of art, or convenient sources of fire wood.) That doesn't mean I'm saying you should wheel all the ones you find, through your city gates! There are other issues besides the utility value of wooden horses. It's the tech that should be celebrated, not necessarily all the products that use it. Tech and products are two very different things, even if related.

There's a pretty easy way to judge the ads for this stuff: what protocols does the product speak? Do you already have software in your repo that speaks that protocol?

And of course, you don't necessarily have to use someone else's service to get the device to work, right? (I'm not even saying you necessarily shouldn't use their service, but if you have to then the product is almost certainly garbage.)
