The thing is, most 100-watt incandescents have long been phased out due to rising efficiency standards.

We spent hours testing each light bulb in this roundup, first testing for qualities such as brightness, color temperature and efficiency and then moving on to our dimming and color quality tests.

The letter, sent in late-2016, called on camera makers to build encryption into their cameras after photojournalists said they face "a variety of threats from border security guards, local police, intelligence agents, terrorists, and criminals when attempting to safely return their footage so that it can be edited and published," according to the Freedom of the Press Foundation, which published the letter.

Trevor Timm, executive director of the Freedom of the Press Foundation, told ZDNet that it's "extremely disappointing the major camera manufacturers haven't even committed to investing resources into more research into this issue, let alone actually building solutions into their cameras."

Photos published online yesterday suggest that China may be testing a ship-mounted electromagnetic railgun.

In tests, prototype weapons shot projectiles at speeds around 7800 kilometres an hour – more than Mach 6 – with a range of around 150 kilometres. But after sinking $500 billion into the project, the US government pulled the plug last year.

Millions of new cars sold in the US and Europe are "connected," having some mechanism for exchanging data with their manufacturers after the cars are sold; these cars stream or batch-upload location data and other telemetry to their manufacturers, who argue that they are allowed to do virtually anything they want with this data, thanks to the "explicit consent" of the car owners -- who signed a lengthy contract at purchase time that contained a vague and misleading clause deep in its fine-print.

After being asked on multiple occasions what the company does with collected data, Natalie Kumaratne, a Honda spokeswoman, said that the company “cannot provide specifics at this time.”

While many iPhone users have experienced perceived slowdowns due to iOS updates over the years, it appears that there’s now proof Apple is throttling processor speeds when a battery capacity deteriorates over time.

“This fix will also cause users to think, 'my phone is slow so I should replace it' not, 'my phone is slow so I should replace its battery,’” says Geekbench’s John Poole.

It’s also clear that Apple, which makes its devices hard to open and repair, could do a better job helping consumers understand the benefits of battery replacement.

One hundred and seventy-one years after the first electrical message was transmitted down a line running alongside the railway between Brussels and Antwerp the final dispatch will be sent and received on 29 December.

So the world won't really change when Belgium finally pulls the plug on its telegram system, but it is another milestone in the long, slow death of a method of communication that once changed the world and which, in its glory days 100 years ago, seemed as though it would never stop.

When Amazon introduced its new $250 Smart Key system a few weeks back, most people were understandably skeptical. The product promises to securely let Amazon delivery folk unlock your front door and place packages inside, with an accompanying camera that tracks every move the deliveryman makes to ensure personal security.

Researchers at Rhino Security Labs demonstrated that by using a simple program within WiFi range, the camera can be not only disabled, but frozen -- presenting the image of a closed door while burglars happily pilfer your possessions.

Coming in 2020, the new Tesla Roadster is said to do the 0 - 60 sprint in 1.9 seconds and continue on through the quarter mile in less than eight seconds.

All that performance won't come cheap, though. The new Tesla Roadster will cost a whopping $250,000, making it Tesla's most expensive car ever. Those who pre-order now (with an at least $50,000 deposit) will get their cars in 2020 -- or thereabouts.
