If you're buying a TV this year — and it's a good year to buy a TV — then you have only a few choices to make before you've picked out a great screen. As well as working out whether you want 4K or HDR, and what screen size you're after in the first place, and what inbuilt smart features you want, your main choice is what TV backlighting technology you want your new big-screen telly to use. We're here to tell you the difference between edge-lit and back-lit LED, LCD and OLED, quantum dot and local dimming, and more.

Cities beefing up their smart infrastructure have tapped the ubiquitous streetlamp to track traffic data and measure pollution. Now, in Los Angeles, some streetlights will help keep the communications network intact after an emergency.
The coolest water slide in the world and perhaps the universe is this black hole water slide in Bremerhaven, Germany's Bad 1 Water Park. The slide starts off completely dark and then lights up with colourful LEDs throughout the journey that make it seem as if you're travelling through some trippy wormhole or teleportation tunnel or something.
Los Angeles recently converted 140,000 of its street lights to energy-efficient LEDs — the largest such upgrade in the world. Now a new partnership with lighting giant Philips will allow the city's Bureau of Street Lighting to wirelessly manage all those street lamps, similar to the way its Hue system allows you to control the mood lighting in your home.
Christmas lights are a uniquely American tradition. That's not just because the first electric Christmas lights appeared in America. The tradition embodies a certain American-ness, an ingenuity and hunger for innovation, that's easily overlooked. America doesn't just make things. America makes things spectacular.
If you're buying an LED lightbulb, you often have to pick between splurging on a fancy one or saving money by buying whatever's cheapest. Cree's original LED bulb is one of the rare LED lightbulbs that works well and costs next-to-nothing, and now the company is offering an even cheaper version.
It's the Star Trek-inspired future we were promised — walls that glow and change colour, perhaps with just a gentle voice command. And it's finally (almost) possible thanks to a series of advances in OLED sheets. This new lighting solution also uses half as much energy than existing fluorescent lights. It is, however, pretty expensive.
There's pretty good chance you have a piece of this year's physics Nobel prize-winning invention in your pocket. The blue light-emitting diode (LED) is found in the screens of millions of phones as well as our bright, new energy-efficient LED lightbulbs. Today, the Nobel Prize in physics was awarded to the three scientists who made this revolutionary discovery.
Chicago, Illinois, isn't exactly a major player in US food production anymore, but that could soon change if companies like Green Sense Farms continue to sprout up. With the help of next-gen LED grow lights, the biggest indoor commercial vertical farm in the US can produce masses of produce regardless of the weather outside.
