As your incandescents burn out, it's a good time to consider switching to LED bulbs. By now, you probably know that LEDs have an impressive lifespan (20-something years!) and are very cost-effective. You probably also know that they're a pricey investment that can run five times more expensive than incandescents.

Despite the cost, now's the right time to switch to LEDs. These bulbs have made significant advances over the last few years, finally delivering the warm light incandescents have comforted us with for decades.

More than ever, there is also an overwhelming number of LED varieties, and … Read more

I can't say I'm a fan of the "Star Trek" reboot, preferring the days when the franchise was so bad it was good, but I have to admire this marketing stunt for "Into Darkness."

We've seen LED quadrotor displays before, and there's no denying that lighting up the night sky with small flying machines has enormous potential.

Ars Electronica Futurelab, the same outfit that illuminated the skies over Linz, Austria, last year, launched 30 quadrotors near London's Tower Bridge and flew in a formation that any Trekkie would salute.… Read more

All so-called LED TVs are really just LCD TVs that use LEDs for their backlight. This backlight creates the light that allows the LCD to create an image. However, there are multiple ways these LED backlights can be arranged, and that arrangement can have a dramatic effect on picture quality.

So here's your guide to all the different versions, with some funky illustrations, too.… Read more

With the flip of a switch Tuesday night, the San Francisco Bay Bridge, already known as one of the world's most amazing bridges, will undergo an epic transformation.

Starting tomorrow evening, anyone looking at the San Francisco side of the Bay Bridge at night will be wowed by the ever-changing swirls, bursts, star fields, and other patterns of the Bay Lights Project, the world's largest LED art installation.

Created by artist Leo Villareal, the project features 25,000 1-inch LEDs strung for 1.8 miles along the bridge's cables that together make up the pixels on what … Read more

At CES in January, Sony announced several LCD TVs with "Triluminos," a new backlighting method that they promise offered "rich, authentic color, and excellent red and green reproduction." Digging deeper, it turns out Triluminos includes an optical component produced by QD Vision, Inc. called "Color IQ" which uses quantum dots to help create light.

OK, so what are quantum dots?… Read more

About 10 months ago, I paid $899 for a no-brand 55-inch TV. It was a roll of the dice, as I had only a handful of user reviews to rely on, but that was the best deal I could find at the time.

Through midnight tomorrow, and while supplies last, TigerDirect has the Proscan PLED5529A 55-inch LED HDTV for $499.99, plus around $50 for shipping. That's after applying coupon code EPE83551 at checkout.

(Note: The sellout risk here is huge. I apologize in advance if you're not able to grab this.)

That's the lowest price I'… Read more

Do movies look weird on your new TV? Does everything have a hyper-real, ultra-smooth motion to it? Are you sure something is happening with the TV's image you don't like, but you can't figure out what?

Chances are, what you're seeing is called the "Soap Opera Effect," as descriptive a moniker as we get in tech, in that this feature makes everything on your TV look like a cheap soap opera.

Here's what it is, what it does, and how to turn it off.… Read more

SAN FRANCISCO--I'm standing behind Leo Villareal, watching the well-known artist calibrate settings in the software running on his screen. Each time he moves a slider, one of the world's largest art installations -- mounted on one of the world's most-famous landmarks -- changes in an instant.

It's a gorgeous evening on the Embarcadero, San Francisco's eastern waterfront, with the San Francisco-Oakland Bay Bridge dominating the landscape in front of us, and a near-full moon doing its best to overcome the typical evening fog cover. Lights from the city, and from Oakland on the other side of the bay reflect brilliantly in the water. And with just the most subtle adjustments in his custom-designed software, Villareal makes thousands of LEDs strung out over the 1.8 mile-long western span of the bridge almost instantaneously change what they're doing, and how they're interacting with each other. … Read more
