New High-Efficiency White OLED Lamp has 10,000-hour Life Span

The Electronics and Telecommunications Research Institute (ETRI), a government-funded think tank, has developed a new organic light emitting diode (OLED) lamp, which has an electricity consumption efficiency four times higher than that of typical incandescent electric lamps.

The ETRI-developed white OLED lamp has an efficiency of 70 lumens per watt, more than four times higher than the typical 15 lumens per watt of incandescent lamps. Remarkably, the new OLED lamp is also an environmentally-friendly invention in which no mercury is used.

In a lab environment, the OLED lamp has a lifetime of 10,000 hours, 20 percent longer than existing fluorescent lamps’ 8,000-hour lifetime. The OLED lamp market is expected to be worth about W3 trillion (US$2.4 billion) by 2015.

How to format the microSD card on Tapo security cameras

One of the most compelling features of Tapo products (like the Wire-Free 2K Outdoor Cam and Indoor/Outdoor Cam) is support for local storage. Many Tapo security cameras let you install a microSD card, so you don't have to rely on cloud storage to save all your videos – instead, they're neatly stored right on your camera. Before you can start using local storage, however, you'll need to format your microSD card. Tapo has some pretty strict requirements for how this works, but the process itself is remarkably simple.

Ready to start saving all your video clips locally? Here's how to format the microSD card on your Tapo security camera.

Blink Mini 2 vs. Ring Stick Up Cam Pro: Which is the best security camera?

The Ring Stick Up Cam Pro on display the 2023 Amazon Fall Devices and Services event.

The Blink Mini 2 is one of the cheapest security cameras you can buy. It's pretty well-rounded too. It's capable of filming in HD and offering support for outdoor use when paired with an optional accessory, making it a great choice for shoppers on a budget. That makes it wildly different from the Ring Stick Up Cam Pro, which carries a hefty price tag and supports both indoor and outdoor use right out of the box without the need to purchase a secondary accessory.

But is the Ring Stick Up Cam Pro a better investment than the affordable Blink Mini 2? From pricing and video resolution to the installation process and additional features, here's a look at the Blink Mini 2 and Ring Stick Up Cam Pro to help you decide which is the best choice for your home.
